Trivia: Big, burly Dan Blocker only did a handful of movies in his 17-year acting career, but he became one of the most beloved and popular television stars of the 1960s for his portrayal of Hoss Cartwright on the Western series Bonanza. Weighing 14 pounds at birth, Blocker was the largest baby ever born in Bowie County, TX. At 18, he stood 6'3" and weighed close to 300 pounds, and was legendary for his physical prowess. Blocker attended the Texas Military Institute and studied for his B.A. at Sul Ross State College, where he initially majored in athletics. His build accidentally led him to the drama department for a production of Arsenic and Old Lace -- a stage hand was needed who was big and strong enough to quickly remove the dummies representing corpses on the set, between acts. While working on the production, Blocker was bitten by the acting bug and switched his major to drama. He pursued his theatrical aspirations in earnest after graduation, working in one season of summer stock before he was drafted. Blocker served in combat during the Korean War, after which he earned a master's degree, married, moved to Los Angeles, and settled down to raise a family, earning his living as a high school teacher. It was his successful audition for the small role of a cavalry lieutenant on Gunsmoke during the 1956 season, in the episode "Alarm at Pleasant Valley," that rekindled Blocker's interest in an acting career. Over the next three years, he took any work that he could get, on programs like Sgt. Preston of the Yukon, Cheyenne, Tales of Wells Fargo, Zane Grey Theater, Wagon Train, Colt .45, Zorro, Maverick, and Richard Diamond, Private Detective. Blocker also got some movie work, portraying a bartender in the offbeat murder mystery The Girl in Black Stockings and an android in Outer Space Jitters, a very late Three Stooges short. His career took an upturn when he got a guest-starring role in an episode of the series The Restless Gun, starring John Payne, in 1958; his work was good enough to catch the attention of the producer, David Dortort. A year later, Dortort was putting together a new, hour-long Western series called Bonanza and cast Blocker in the role of "Hoss" Cartwright, the big-boned, good-natured middle son in a ranching family near Virginia City, NV, set in the mid- to late 19th century (the time frame of Bonanza was always vague, with stories shifting between the early 1860s to the 1870s and 1880s). Blocker's character's real name, incidentally, was Eric, but Hoss -- a nickname from his mother's Norwegian language that meant "friend" -- was what he was known as to everyone on the series and all viewers. Despite the weaknesses in the scripts during the early seasons, the role was a dream part for the actor, who got a chance to display his gentle, sensitive side as well as his gift for comedy, and also work in a serious dramatic context as well on many occasions, and show off his brute strength as well. It is arguable that Blocker was the most popular member of the cast during the 1960s; he was especially beloved of younger viewers, in part because his character was always very sympathetic to children. In contrast to the other stars of the series, Blocker's big-screen career wasn't halted by his work on Bonanza. He appeared in The Errand Boy, playing himself in an uncredited cameo, and played a role in the Frank Sinatra movie Come Blow Your Horn. Blocker got his first major movie part five years later in the Sinatra film Lady in Cement (1968), playing Waldo Gronsky, a burly, potentially murderous thug who hires private detective Tony Rome (played by Sinatra) to find his missing girlfriend. By the end of the 1960s, Blocker was taken seriously enough as an actor to star in two features, Something for a Lonely Man, a beautiful and poignant Western/comedy-drama, and the broader comedy The Cockeyed Cowboys of Calico County. Some of Blocker's television appearances separate from Bonanza also reflected his personal side -- his politics were essentially liberal Democratic (in sharp contrast to the conservative Republican sympathies of his co-stars Michael Landon and Lorne Greene), and he appeared in several public service announcements promoting brotherhood and racial tolerance, as well as on one television special that gently satirized American popular culture, starring Henry Fonda. He was also part of the liberal contingent in the 1971 John Wayne-hosted patriotic special Swing Out, Sweet Land. In 1972, Blocker was chosen for what could have been the breakthrough role to a major movie career, when he won the part of Roger Wade, the has-been author in Robert Altman's revisionist detective movie The Long Goodbye. In May of that year, however, he went into the hospital for routine gall bladder surgery, and during recovery he died suddenly of a blood clot in his lung. Sterling Hayden replaced Blocker in The Long Goodbye, which was dedicated to the actor's memory. Blocker's passing, immediately before the shooting for the 1972-1973 season of Bonanza was to begin, signed the death knell for the series. The cast and crew were genuinely shaken by his sudden death; scripts had to be hastily rewritten to explain the passing of Hoss Cartwright, and Blocker's absence and the reason behind it removed any element of lightheartedness that the series had displayed. The final season, despite the best efforts of surviving stars Lorne Greene, Michael Landon, and David Canary, was characterized by grim, downbeat stories and a dark mood that seemed to repel longtime viewers. Coupled with this change in tone, the NBC network moved Bonanza from its longtime Sunday nighttime slot to Tuesday nights, where it died a quick death, cancellation coming halfway through the 1972-1973 season. Blocker left behind a wife and four children, among them actor Dirk Blocker and director/producer David Blocker. He also left behind a legacy of good will that survives to this day, as Bonanza is in perpetual reruns on various cable channels, decades after its cancellation. Significantly, the final season, in which he did not appear, is the body of episodes that is shown (and requested) the least of its 14 years' worth of programs.

Trivia: Square-jawed, mellow-voiced character actor David Canary achieved his greatest prominence on television, in roles that typecast him as a "man's man" with an unmistakably tough edge but a smooth demeanor and approach. Born in Elwood, IN, Canary grew up in Ohio as the son of a JC Penney manager. He took to musical performance (as a baritone vocalist) during adolescence, then after high school attended the University of Cincinnati on a football scholarship and concurrently took classes at the Cincinnati Conservatory of Music, qualifying as the first person to combine studies at both institutions, graduating as a music major in voice from the university. During that period, the university theater director, Paul Rutledge, observed Canary's innate dramatic gifts and strongly encouraged the student to try out for roles in numerous productions, many of which he landed with great ease, thereby opening himself up to a talent all but unrecognized and untapped, and paving the way for a prestigious foray into acting that commenced with several years of summer stock. Canary began his professional acting career on-stage, in musicals, but he made his Broadway debut in the play Great Day in the Morning, opposite Colleen Dewhurst. His career was put on hold for a time when he was drafted into the U.S. Army and stationed at a base in Texas, but he made the most of it, entertaining the troops and winning the All Army Entertainment Contest for best popular singer. When his service time was completed, Canary returned to the theater, but it wasn't long before he moved into filmed work.As a professional actor, Canary divided his time between big- and small-screen outings, but placed his strongest emphasis on television. He is best known for two ongoing, multi-season series roles: Candy, a wanderer hired onto the Cartwright property as a ranch hand, on the immensely popular Western saga Bonanza (a part held from 1967 through 1970 and again during the final season of 1972-1973), and -- on a much different note -- long-running portrayals of twins Adam and Stuart Chandler on the ABC daytime drama All My Children. Canary retired from acting in 2013; he died in 2015, at age 77.

Trivia: Though typecast as a dull-witted brute, Austrian-born Mike Mazurki was the holder of a Bachelor of Arts degree from Manhattan College. During the 1930s, he was a professional football and basketball player, as well as a heavyweight wrestler. His clock-stopping facial features enabled Mazurki to pick up bit and supporting roles in such films as The Shanghai Gesture (1941) and Dr.Renault's Secret (1943). Larger parts came his way after his indelible portrayal of psychotic brute Moose Malloy in 1944's Murder My Sweet. His trademarked slurred speech was reportedly the result of an injury to his Adam's apple, incurred during his wrestling days. While villainy was his bread and butter, Mazurki enjoyed working with comedians like Jerry Lewis and Lou Costello; he was particularly fond of the latter because the diminutive Costello treated him with dignity and respect, defending big Mike against people who treated the hulking actor like a big dumb lug. Mazurki's many TV appearances included a regular role on the short-lived 1971 sitcom The Chicago Teddy Bears. In 1976, Mike Mazurki was effectively cast as a kindly trapper in the family-oriented "four-waller" Challenge to Be Free, which ended up a cash cow for the veteran actor.

Trivia: A distinguished Canadian stage, radio, film, and TV actor, Eric Christmas is probably best known to American audiences as Mr. Carter in the two Porky's films of the 1980s, or as Senator Polk in The Attack of the Killer Tomatoes! (1980), or Roland the Butler in Warren Beatty's Bugsy (1992). Christmas also played Morten Kill in Steve McQueen's courageous adaptation of Henrik Ibsen's An Enemy of the People (1979). Eric Christmas' TV-series assignments in America have included the roles of Ben Hampton in The Sandy Duncan Show (1972) and Harry "The Hunchback" Schanstra in Wiseguys (1987-1988 season).

Trivia: One of the youngest "old codgers" in show business, Arthur Hunnicutt left college when funds ran out and joined an acting troupe in Martha's Vineyard, Massachusetts. His first important New York engagement was in the Theatre Guild's production of Love's Old Sweet Song. Hunnicutt entered films in 1942, specializing in grizzled western sidekicks even though he was only in his early 30s. When Percy Kilbride retired from the "Ma and Pa Kettle" series in 1955, Hunnicutt, still a youngster in comparison to Kilbride's sixtysomething co-star Marjorie Main, filled the gap in The Kettles in the Ozarks (1955). And when director Howard Hawks needed someone to play a Walter Brennan-type role when Brennan wasn't available for The Big Sky (1952) and El Dorado (1967), Hunnicutt was the man of the hour (his work in Big Sky won him an Oscar nomination). Arthur Hunnicutt was last seen in 1975's The Moonrunners, at long playing someone closer to his own age.

Trivia: The son of a Jewish movie-publicist father and an Irish Catholic musical-comedy actress, Michael Landon grew up in a predominantly Protestant New Jersey neighborhood. The social pressures brought to bear on young Michael, both at home and in the schoolyard, led to an acute bedwetting problem, which he would later dramatize (very discreetly) in the 1976 TV movie The Loneliest Runner. Determined to better his lot in life, Landon excelled in high school athletics; his prowess at javelin throwing won him a scholarship at the University of Southern California, but a torn ligament during his freshman year ended his college career. Taking a series of manual labor jobs, Landon had no real direction in life until he agreed to help a friend audition for the Warners Bros. acting school. The friend didn't get the job, but Landon did, launching a career that would eventually span nearly four decades. Michael's first film lead was in the now-legendary I Was a Teenage Werewolf (1957), widely derided at the time but later reassessed as one of the better examples of the late-'50s "drive-in horror" genre. The actor received his first good reviews for his performance as an albino in God's Little Acre. This led to his attaining the title role in 1959's The Legend of Tom Dooley, which in turn was instrumental in his being cast as Little Joe Cartwright on the popular TV western Bonanza. During his fourteen-year Bonanza stint, Landon was given the opportunity to write and direct a few episodes. He carried over these newfound skills into his next TV project, Little House on the Prairie, which ran from 1974 to 1982 (just before Little House, Landon made his TV-movie directorial bow with It's Good to Be Alive, the biopic of baseball great Roy Campanella). Landon also oversaw two spinoff series, Little House: The New Beginning (1982-83) and Father Murphy (1984). Landon kept up his career momentum with a third long-running TV series, Highway to Heaven (1984-89) wherein the actor/producer/director/writer played guardian angel Jonathan Smith. One of the most popular TV personalities of the '70s and '80s, Landon was not universally beloved by his Hollywood contemporaries, what with his dictatorial on-set behavior and his tendency to shed his wives whenever they matured past childbearing age. Still, for every detractor, there was a friend, family member or coworker who felt that Landon was the salt of the earth. In early 1991, Landon began work on his fourth TV series, Us, when he began experiencing stomach pains. In April of that same year, the actor was informed that he had inoperable pancreatic cancer. The courage and dignity with which Michael Landon lived his final months on earth resulted in a public outpouring of love, affection and support, the like of which was seldom witnessed in the cynical, self-involved '90s. Michael Landon died in his Malibu home on July 1, 1991, with his third wife Cindy at his side.

Trivia: White-haired, patriarchal Canadian actor Lorne Greene attended Queen's University in pursuit of a chemical engineering degree. Amateur college theatricals whetted his appetite for the stage, and upon graduation he decided upon a performing career. He started out on radio, eventually emerging as Canada's top newscaster, designated "the voice of the CBC" (For a while, Greene managed a mail-order announcer's school; one of the "pupils" was Leslie Nielsen). Moving to New York in 1950, Greene became a stage, film and TV actor, co-starring on Broadway with Katherine Cornell in Prescott Proposals and in films with the likes of Paul Newman, Ginger Rogers and Joan Crawford, generally in villainous roles. In 1959, Greene was cast as Ben Cartwright, owner of the Ponderosa ranch and father of three headstrong sons, in TV's Bonanza. He would hold down this job until 1972; during the series' run, Greene unexpectedly became a top-ten recording artist with his hit single "Ringo." Upon the cancellation of Bonanza, Greene vowed he'd retire, but within one year he was playing a private detective on the brief TV weekly Griff. Five years later, he starred on the network sci-fier Battlestar Gallactica. Active as chairman of the National Wildlife Foundation, Greene put forth the organization's doctrine in his popular syndicated TV series Lorne Greene's Last of the Wild. His final weekly television appearance was on the 1980 adventure series Code Red. In 1987, Lorne Greene was all set to recreate Ben Cartwright for the 2-hour TV movie Bonanza: The Next Generation, but he died before shooting started and was replaced by John Ireland.

Trivia: Though best known to modern filmgoers as a horror star, cadaverous John Carradine was, in his prime, one of the most versatile character actors on the silver screen. The son of a journalist father and physician mother, Carradine was given an expensive education in Philadelphia and New York. Upon graduating from the Graphic Arts School, he intended to make his living as a painter and sculptor, but in 1923 he was sidetracked into acting. Working for a series of low-paying stock companies throughout the 1920s, he made ends meet as a quick-sketch portrait painter and scenic designer. He came to Hollywood in 1930, where his extensive talents and eccentric behavior almost immediately brought him to the attention of casting directors. He played a dizzying variety of distinctive bit parts -- a huntsman in Bride of Frankenstein (1935), a crowd agitator in Les Miserables (1935) -- before he was signed to a 20th Century Fox contract in 1936. His first major role was the sadistic prison guard in John Ford's Prisoner of Shark Island (1936), which launched a long and fruitful association with Ford, culminating in such memorable screen characterizations as the gentleman gambler in Stagecoach (1939) and Preacher Casy ("I lost the callin'!") in The Grapes of Wrath (1940). Usually typecast as a villain, Carradine occasionally surprised his followers with non-villainous roles like the philosophical cab driver in Alexander's Ragtime Band (1938) and Abraham Lincoln in Of Human Hearts (1938). Throughout his Hollywood years, Carradine's first love remained the theater; to fund his various stage projects (which included his own Shakespearean troupe), he had no qualms about accepting film work in the lowest of low-budget productions. Ironically, it was in one of these Poverty Row cheapies, PRC's Bluebeard (1944), that the actor delivered what many consider his finest performance. Though he occasionally appeared in an A-picture in the 1950s and 1960s (The Ten Commandments, Cheyenne Autumn), Carradine was pretty much consigned to cheapies during those decades, including such horror epics as The Black Sleep (1956), The Unearthly (1957), and the notorious Billy the Kid Meets Dracula (1966). He also appeared in innumerable television programs, among them Twilight Zone, The Munsters, Thriller, and The Red Skelton Show, and from 1962 to 1964 enjoyed a long Broadway run as courtesan-procurer Lycus in A Funny Thing Happened on the Way to the Forum. Though painfully crippled by arthritis in his last years, Carradine never stopped working, showing up in films ranging from Everything You Always Wanted to Know About Sex But Were Afraid to Ask (1972) to Peggy Sue Got Married (1984). Married four times, John Carradine was the father of actors David, Keith, Robert, and Bruce Carradine.

Trivia: Ivor Francis began his entertainment career as a teen appearing on the radio in his native Toronto, Canada. During WW II he served in the RAF and afterward emigrated to New York where he landed a job on a daily serial Me Perkins. This led him to appear in several Broadway shows and from there to feature films such as I Love My Wife. During the '70s he frequently worked as an actor in Disney films, including World's Greatest Athlete. Francis also appeared frequently on television series and in made-for-TV- movies; he was a regular on Room 222. Later in his career he began teaching stagecraft in Los Angeles and New York. His daughter Genie Francis has played "Laura" on the television soap General Hospital for many years.

Trivia: "A very funny guy -- funnier than most gave him credit for," as one director described him, lanky, slow-moving Guy Wilkerson is fondly remembered for playing comedy sidekick Panhandle Perkins in the 1942-1945 PRC Texas Rangers film series, a low-rent competition for Republic Pictures' popular Three Mesquiteers Westerns. As Panhandle, Wilkerson's comedy was never intrusive and often used merely as a slow-witted counterpoint to the action. In Hollywood from at least 1937 (some sources claim he appeared onscreen as early as the 1920s), Wilkerson had honed his skills in minstrel shows, burlesque, and vaudeville, but away from his sidekick duties at PRC, he was usually seen playing less humorous characters, notably ministers or undertakers. Appearing in hundreds of feature films and television series over three decades, Guy Wilkerson was last seen in the crime thriller The Todd Killings in 1971, the year of his death from cancer.

Trivia: Bald, cadaverous, hollow-eyed, doom-voiced actor Milton Parsons began appearing in films in the late 1930s. In an era wherein being typecast in Hollywood assured an actor a steady paycheck, Parsons fattened his bank account by playing dozens of undertakers and morticians. He was also an effective psychotic type, most notably as the lead in 1942's The Hidden Hand. Parsons entered the "film noir" hall of fame in the tiny role of the jury foreman in 1947's They Won't Believe Me; the film's unforgettable final image was a screen-filling close-up of Parsons, gloomily intoning an all-too-late "Not Guilty." Active into the 1970s, Parsons showed up in TV series ranging from Twilight Zone to The Dick Van Dyke Show, his morbid appearance enhanced by the addition of a satanic goatee. Even in his last roles, Milton Parsons adhered strictly to type; in the 1976 TV movie Griffin and Phoenix, for example, he portrayed a guest lecturer at a support group for terminally ill cancer victims.
