Trivia: Guy Williams never became a movie star despite his good looks and a charismatic screen presence, but on television he was a star twice over, in the 1960s as Professor John Robinson on the Irwin Allen-produced series Lost in Space and, for those with longer memories, in the title role of the Walt Disney-produced series Zorro; he also cut a memorable presence in a series of episodes of Bonanza during the early '60s, as a cousin of the Cartwrights from south of the border. Born Armando Catalano in New York City, he was the son of one of Italy's champion swordsmen, and he was an expert fencer himself by the time he was in his teens. His good looks made him a natural as a model, and he appeared in numerous newspapers and magazines during the early to mid-'40s. In 1946, at the age of 23, he was signed to MGM, but the studio's declining postwar period proved a dead end of tiny bit roles that went nowhere. He studied acting with Sanford Meisner and was serious about being more than a model who could read lines, but it wasn't until the 1950s that he got his chance. In 1952, Williams was signed to Universal-International, where he finally began getting some respectable screen time, once he got past his initial Universal appearance, in Bonzo Goes to College and a thankless role in Nathan Juran's swashbuckler The Golden Blade. In The Mississippi Gambler (1953), The Man From the Alamo (1953), and The Last Frontier (1956), Williams played small to medium-sized supporting roles that showed him off to good advantage as an actor. His career seems to have stalled at the point where he appeared in American International Pictures' release of I Was a Teenage Werewolf (1957). In 1957, however, Williams became a star on television when he was chosen to play the title role in the Disney television series Zorro. It was only in production for two seasons, but Disney's perpetual presence on television brought Williams' dashing heroic figure into households for years after the initial run had ended. Williams was subsequently pegged by the producers of Bonanza as a potential replacement for Pernell Roberts in the series, and he was tried out in the role as the Mexican-born cousin of the Cartwrights across numerous episodes. In 1963, he also starred in the German-made international film Captain Sinbad, directed by American adventure film specialist Byron Haskin. In 1964, Williams was cast in the most familiar role of his career, as Professor John Robinson on the series Lost in Space (1965-1968); although he was a co-star with June Lockhart, he came to be partly overshadowed by Billy Mumy and Jonathan Harris in the story lines. Nevertheless, he provided a firm dramatic anchor for the series. As with most of the cast of Lost in Space, work was relatively hard to come by once it was canceled, but Williams evidently had no worries about money, having done well in his own investments and various business ventures. He also discovered on a visit to South America that he was very much a pop culture hero in most of Latin America, where Zorro had been an enormous success on television and was seemingly being rerun in perpetuity. He moved to Buenos Aires, enjoying a very comfortable retirement from the mid-'70s, and died of a heart attack there in 1989.

Trivia: The son of Lebanese parents, American actor Tige Andrews, born Tiger Androwaous, has played supporting roles on television and in films where he is usually cast as an amiable bad-guy. He is best known for his television work; he was a regular on the 1970s series Mod Squad.

Trivia: A third-generation actor, Harold J. Stone made his stage debut at age six with his father, Jacob Hochstein, in the Yiddish-language play White Slaves. Stone had one line--"Mama!"--which he managed to forget on opening night. He didn't act again until after his graduation from New York University. After gleaning valuable experience in radio, he returned to the stage in George Jessel's production of Little Old New York at the 1939 World's Fair. Stone made his Broadway bow shortly afterward in Sidney Kingsley's The World We Make, and thereafter was seldom unemployed. In 1952, he began the first of many TV-series gigs when he replaced Philip Loeb as Jake on The Goldbergs; within a decade, he was averaging 20 TV appearances per year. In films from 1956, the harsh-voiced, authoritative Stone was most often seen as big-city detective (as in Hitchcock's The Wrong Man), generals, and gangsters (he was Frank Nitti in 1967's St. Valentine's Day Massacre). Usually billed at the top of the supporting cast, Stone enjoyed a rare above-the-title starring assignment when he played investigator John Kennedy in the 1959 syndicated TV series Grand Jury. His other weekly-series roles included Hamilton Greeley (a character based on New Yorker maven Harold Ross) in My World and Welcome to It (1969) and Sam Steinberg in Bridget Loves Bernie (1972). In the latter stages of his career, Harold J. Stone unexpectedly found himself a favorite of Jerry Lewis, co-starring in Lewis' The Big Mouth (1967), Which Way to the Front? (1970) and Hardly Working (1980).
