Trivia: Famed for his ratchety voice and cold-fish stare, William Demarest was an "old pro" even when he was a young pro. He began his stage career at age 13, holding down a variety of colorful jobs (including professional boxer) during the off-season. After years in carnivals and as a vaudeville headliner, Demarest starred in such Broadway long-runners as Earl Carroll's Sketch Book. He was signed with Warner Bros. pictures in 1926, where he was briefly paired with Clyde Cook as a "Mutt and Jeff"-style comedy team. Demarest's late-silent and early-talkie roles varied in size, becoming more consistently substantial in the late 1930s. His specialty during this period was a bone-crushing pratfall, a physical feat he was able to perform into his 60s. While at Paramount in the 1940s, Demarest was a special favorite of writer/director Preston Sturges, who cast Demarest in virtually all his films: The Great McGinty (1940); Christmas in July (1940); The Lady Eve (1941); Sullivan's Travels (1942); The Palm Beach Story (1942); Hail the Conquering Hero (1944); Miracle of Morgan's Creek (1944), wherein Demarest was at his bombastic best as Officer Kockenlocker; and The Great Moment (1944). For his role as Al Jolson's fictional mentor Steve Martin in The Jolson Story (1946), Demarest was Oscar-nominated (the actor had, incidentally, appeared with Jolie in 1927's The Jazz Singer). Demarest continued appearing in films until 1975, whenever his increasingly heavy TV schedule would allow. Many Demarest fans assumed that his role as Uncle Charlie in My Three Sons (66-72) was his first regular TV work: in truth, Demarest had previously starred in the short-lived 1960 sitcom Love and Marriage.

Trivia: Mississippi-born Roscoe Ates spent a good portion of his childhood overcoming a severe stammer. Entering show business as a concert violinist, the shriveled, pop-eyed Ates found the money was better as a vaudeville comedian, reviving his long-gone stutter for humorous effect. In films from 1929, Ates appeared in sizeable roles in such films as The Champ (1931), Freaks (1932) and Alice in Wonderland (1933), and also starred in his own short subject series with RKO and Vitaphone. Though his trademarked stammer is something of an endurance test when seen today, it paid off in big laughs in the 1930s, when speech impediments were considered the ne plus ultra of hilarity. By the late 1930s Ates's popularity waned, and he was reduced to unbilled bits in such films as Gone with the Wind (1939) and Dixie (1942). His best showing during the 1940s was as comic sidekick to singing cowboy Eddie Dean in a series of 15 low-budget westerns. Remaining busy in films and on TV into the 1960s, Roscoe Ates made his last appearance in the 1961 Jerry Lewis comedy The Errand Boy.

Trivia: Born in Oklahoma of Cherokee-Irish stock, Ben Johnson virtually grew up in the saddle. A champion rodeo rider in his teens, Johnson headed to Hollywood in 1940 to work as a horse wrangler on Howard Hughes' The Outlaw. He went on to double for Wild Bill Elliot and other western stars, then in 1947 was hired as Henry Fonda's riding double in director John Ford's Fort Apache (1948). Ford sensed star potential in the young, athletic, slow-speaking Johnson, casting him in the speaking role of Trooper Tyree in both She Wore a Yellow Ribbon (1949) and Rio Grande (1950). In 1950, Ford co-starred Johnson with another of his protégés, Harry Carey Jr., in Wagonmaster (1950). Now regarded as a classic, Wagonmaster failed to register at the box office; perhaps as a result, full stardom would elude Johnson for over two decades. He returned periodically to the rodeo circuit, played film roles of widely varying sizes (his best during the 1950s was the pugnacious Chris in George Stevens' Shane [1953]), and continued to double for horse-shy stars. He also did plenty of television, including the recurring role of Sleeve on the 1966 western series The Monroes. A favorite of director Sam Peckinpah, Johnson was given considerable screen time in such Peckinpah gunfests as Major Dundee (1965) and The Wild Bunch (1969). It was Peter Bogdanovich, a western devotee from way back, who cast Johnson in his Oscar-winning role: the sturdy, integrity-driven movie house owner Sam the Lion in The Last Picture Show (1971). When not overseeing his huge horse-breeding ranch in Sylmar, California, Ben Johnson has continued playing unreconstructed rugged individualists in such films as My Heroes Have Always Been Cowboys (1991) and Radio Flyer (1992), in TV series like Dream West (1986, wherein Johnson was cast as frontier trailblazer Jim Bridger), and made-for-TV films along the lines of the Bonanza revivals of the 1990s.

Trivia: The son of an English-immigrant clothier, Mike Kellin decided to become an actor in the second grade, after watching a school production of A Christmas Carol. The restless Kellin briefly attended three colleges before serving in the Navy in World War II. After flunking out of Yale Drama School, Kellin headed to New York, where he studied acting under Lee Strasberg, Sanford Meisner and Stella Adler. Denied leading-man assignments because of what he described as his "lived-in face," Kellin's big Broadway break came in the role of the abrasive sergeant in the 1949 Broadway comedy At War with the Army; he would reprise his role in the 1950 film version, which starred Martin and Lewis. Kellin went on to win the Tony award for his performance in the 1956 Rodgers and Hammerstein musical Pipe Dream. In 1960, Kellin was cast as slovenly Chief Mate McCarthy in The Wackiest Ship in the Army; when this film was adapted into a TV series in 1965, Kellin came along for the ride in substantially the same role, though the character was rechristened as Chief Petty Officer Willie Miller. Mike Kellin's most celebrated movie appearance was his Oscar-nominated role as the father of the imprisoned protagonist in Midnight Express (1978).
