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: 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: Coleman attended a Virginia military school before studying law and serving in the army. While attending the University of Texas, Coleman became attracted to acting, and headed to New York, where he studied at the Neighborhood Playhouse. After stage experience and TV work, Coleman made his movie debut in 1965's The Slender Thread. Minus his trademarked mustache for the most part in the mid-1960s, Coleman specialized in secondary character roles. He began to branch into comedy during his supporting stint as obstetrician Leon Bessemer on the Marlo Thomas sitcom That Girl, but his most memorable role would come in 1980 as the nasty, chauvinistic boss in 9 to 5. He would go on to appear in other films, like On Golden Pond [1981], The Beverly Hillbillies [1993], You've Got Mail [1998], and Moonlight Mile, but the actor found more success in television, appearing on a few cult hits that were tragically cancelled, like Drexell's Class and Madman of the People, as well as The Guardian, Courting Alex, Heartland, and Boardwalk Empire.

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: American actor Bill Zuckert's long career included appearances on stage, screen, radio, and television. He made his acting debut on radio in 1941. During the 1970s, he made frequent television appearances on programs ranging from Dynasty to The Mary Tyler Moore Show to Little House on the Prairie. Zuckert made his last appearance in two films of 1994, Ace Ventura, Pet Detective and Naked Gun 33 1/3: The Final Insult. Zuckert was an active member of the Screen Actors Guild and the American Federation of Television and Radio Artists. For the latter, he played a key role in developing a new member program. Zuckert also launched the practice of holding casting showcases for members of both guilds. Zuckert died of pneumonia in Woodland Hills, CA, at age 76.

Trivia: American actor Chick Chandler was an army brat, the son of a much-travelled military surgeon. Chandler was groomed for a career in uniform, but he dropped out of military school and headed for Hollywood. He worked as a prop man and gopher before making his first film appearance in 1925's Red Love. Polishing his craft in vaudeville and legitimate theatre, Chandler was much in demand once the movies began to talk in 1929. He starred in his own series of two-reelers at RKO, and also made feature-film appearances in such RKO features as Melody Cruise and Murder on a Honeymoon. By the mid-1930s, Chandler was an accomplished monologist and hoofer, enabling him to attain a 20th Century-Fox contract. Perhaps too brash and abrasive to make it as a leading man, Chandler nonetheless thrived as a supporting actor. Once in a while he'd play the romantic lead, but it was usually in poverty-row items like PRC's Seven Doorways to Death (1943). While he remained in films until the late 1960s, it was television that afforded Chick Chandler his most substantial latter-day assignments: he co-starred with John Russell on the 1955 syndicated adventure weekly Soldiers of Fortune, and was a regular as the hero's father on the 1961 "newlywed" sitcom One Happy Family.

Trivia: A top-flight character actor and sometime leading man, Gregory Walcott managed to bridge the tail-end of the studio system, the heyday of series television, and the boom years of the post-studio 1970s, and carve a notable career in the process. He was born Bernard Mattox in 1928 (some sources say 1932) in Wendell, NC, a small town about 10 miles east of the state capitol of Raleigh. After serving in the Army following the end of the Second World War, he decided to try for an acting career and hitchhiked his way to California. He managed to get work in amateur and semi-professional theatrical productions and was lucky enough to be spotted in a small role in one of these by an agent. That resulted in his big-screen debut, in an uncredited role in the 20th Century-Fox drama Red Skies of Montana (1952). With his 6'-plus height, impressive build, and deep voice, Walcott would seem to have a major career in front of him, but the movie business of the 1950s was in a state of constant retrenchment, battling the intrusion of television and the eroding of its audience. For the next three years, he had little but bit parts in films, some of them major productions. His performance as the drill instructor in the opening section of Raoul Walsh's Battle Cry (1955) was good enough to get him a contract with Warner Bros. He subsequently played supporting roles in Mister Roberts (1955) and in independent productions such as Badman's Country (1958), and also started showing up on television with some regularity. And with each new role, he seemed to gather momentum in his career.As luck would have it, however, Walcott's most prominent role of the 1950s ended up being the one he received the lowest fee for doing, and that he also thought the least of, and also one that, for decades, he was loathe to discuss, on or off the record: as Jeff Trent, the hero of Plan 9 From Outer Space. Walcott's work on the magnum opus of writer/producer/director Edward D. Wood, Jr. amounted to less than a week's work, and he was so busy in those days that one can easily imagine him forgetting about it as soon as his end of the shoot was over. And the movie was scarcely even seen on its initial release in the summer of 1959 and went to television in the early '60s in a package that usually had it relegated to "shock theater" showcases and the late-night graveyard (no pun intended). But the ultra-low-budget production, renowned for its eerily, interlocking values of ineptitude and entertainment, has become one of the most widely viewed (and deeply analyzed) low-budget movies of any era in the decades since.As this oddity in his career was starting to gather its fans (some would say fester), Walcott had long since moved on to co-starring in the series 87th Precinct and guest-starring roles in series television. Across the 1960s, he remained busy and had a chance to do especially good work on the series Bonanza, which gave him major guest-starring roles in seven episodes between 1960 and 1972. In one of these, "Song in the Dark" (1962), Walcott even had a chance to show off his singing voice, a talent of his that was otherwise scarcely recognized in a three-decade career. By the late '60s, he had also moved into production work, producing and starring in Bill Wallace of China (1967), the story of a Christian missionary. During the 1970s, Walcott finally started to get movie roles that were matched in prominence to his talent, most especially in the films of Clint Eastwood. He remained busy as a prominent character actor and supporting player -- part of that category of performers that includes the likes of Richard Herd and James Cromwell -- into the 1980s. He had retired by the start of the 1990s, but was called before the cameras once more for an appearance in Tim Burton's movie Ed Wood. Walcott died in 2015, at age 87.

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: A former pro baseball player, Bing Russell eased into acting in the 1950s, appearing mostly in westerns. Russell could be seen in such bonafide classics as The Horse Soldiers (1959) and The Magnificent Seven (1960), and not a few bow-wows like Billy the Kid vs. Dracula (1966). From 1961 through 1973, Russell played the semiregular role of Deputy Clem on the marathon TV western series Bonanza. When time permitted, he also dabbled in screenwriting. The father of film star Kurt Russell, Bing Russell has acted with his son on several occasions, most memorably in the role of Vernon Presley in the 1979 TV-movie hit Elvis.
