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: Al Ruscio played character roles since his film debut in Al Capone (1959). His best-known roles included crime boss Leo Cuneo in The Godfather: Part III (1990) and a recurring role on Life Goes On; he also appeared in the pilot episode of Seinfeld as the manager of Monk's Café. Ruscio worked as an acting teacher for years and regularly appeared in stage productions in Los Angeles. He passed away in 2013 at age 89.

Trivia: Tough-talking American character actor Perry Lopez played "ethnic" roles from the time of his his stage debut in the early 1950s. Signed to a Warner Bros. contract in 1955, Lopez lent support to such studio projects as Mister Roberts (1955), The McConnell Story (1956) and The Violent Road (1958). He is best remembered as police officer Lou Escobar in Roman Polanski's Chinatown (1974). Perry Lopez reprised this uniformed character (now promoted to captain) in the 1990 Chinatown sequel The Two Jakes. Lopez died of lung cancer in February 2008.

Trivia: Wisconsinite John Litel was a graduate of the University of Pennsylvania. When World War I broke out in Europe, Litel didn't feel like waiting until America became officially involved and thus joined the French army, serving valiantly for three years. Returning to America, Litel studied at the American Academy of Dramatic Arts and entered into the peripatetic world of touring stock companies. His first film was the 1929 talkie The Sleeping Porch, which starred top-hatted comedian Raymond Griffith. He settled in Hollywood for keeps in 1937, spending the next three decades portraying a vast array of lawyers, judges, corporate criminals, military officers, and even a lead or two. Litel was a regular in two separate "B"-picture series, playing the respective fathers of Bonita Granville and James Lydon in the Nancy Drew and Henry Aldrich series. On television, John Litel was appropriately ulcerated as the boss of Bob Cummings on the 1953 sitcom My Hero.
