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: Supporting actor Mark Goddard first appeared onscreen in the '60s. He is now an agent.

Trivia: Instantly recognizable for his sophisticated and grim-visaged manner of speech and his sharp, expressive features, popular character actor Jonathan Harris' villainous role on the beloved series Lost in Space earned him both a noted spot in the annals of television history and a warm place in the hearts of TV viewers everywhere. Born Jonathan Charasuchin in November 1914, the son of impoverished Russian-Jewish immigrants worked as a pharmacy box boy in his early teens, later pursuing a pharmacology degree from Fordham University. Though successful in his early career, the young pharmacist couldn't resist the lure of the stage, and after changing his surname, Jonathan Harris began making frequent appearances on the local stock company stages. Though his talent was undeniable, Harris felt that his thick New York accent impeded his ability to pursue the roles he wanted. Taking to British film as a means to remedy this, Harris took in as many British movies as possible in order to re-create their speech patterns, an ability he used to striking effect on both stage and screen -- so effective, in fact, that it became his trademark, with many of his fans failing to realize that offscreen, Harris' accent was pure "New Yorkese." Eventually drawn to the bright lights of Broadway, Harris became a fixture in the office of the Henry Miller Theater. Introduced to Gilbert Miller by Miller's sympathetic secretary, Harris' Broadway career subsequently took off following a small role in The Heart of a City. After finding a steady career on the stages of New York and on live television, Harris packed his bags for Hollywood and made his feature debut in 1953's Botany Bay. Television roles in The Twilight Zone and Bewitched followed in short succession, and in 1965 Harris received the biggest break of his career when cast in Lost in Space. Crediting producer Irwin Allen with giving him free rein regarding character interpretation, Harris quickly became the biggest draw of Lost in Space due to his unique comic villainy. Despite his co-stars' rumored aggravation over his breakout performance, Harris' utter professionalism and genuinely friendly demeanor won over cast and crew as effectively as his villainous persona did the viewing public. Also appearing in such popular television series as Zorro, Sanford and Son, and Night Gallery, Harris would frequently lend his distinct voice to numerous cartoons (Darkwing Duck, Freakazoid!) in addition to the infrequent theatrical release (A Bug's Life [1998] and Toy Story 2 [1999]). Married to high school sweetheart Gertrude in 1938, the couple's marriage endured to Harris' death in late 2002 resulting from a blood clot in his heart. He was 87.

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).

Trivia: Stage actor Peter Brocco made his first film appearance in 1932's The Devil and Deep. He then left films to tour in theatrical productions in Italy, Spain and Switzerland. Returning to Hollywood in 1947, Brocco could be seen in dozens of minor and supporting roles, usually playing petty crooks, shifty foreign agents, pathetic winos and suspicious store clerks. His larger screen roles included Ramon in Spartacus (1960), The General in The Balcony (1963), Dr. Wu in Our Man Flint (1963), and the leading character in the Cincinnati-filmed black comedy Homebodies (1974). The addition of a fuzzy, careless goatee in his later years enabled Brocco to portray generic oldsters in such films as One Flew Over the Cuckoo's Nest (1977), The One and Only(1977), Throw Momma From the Train (1989) and War of the Roses (1983). In 1983, Peter Brocco was one of many veterans of the Twilight Zone TV series of the 1950s and 1960s to be affectionately cast in a cameo role in Twilight Zone: The Movie (1983).

Trivia: Chuck Roberson was a rancher before serving in World War II. Upon his discharge, he sought out film work as a stunt man. While under contract to Republic Pictures, Roberson doubled for John Wayne in Wake of the Red Witch (1948). Thereafter, he worked in virtually all of Wayne's films as stunt double, action coordinator, second-unit director and bit actor. His best speaking part was Sheriff Lordin in the Duke's McClintock (1963). Chuck Roberson's career served as the inspiration for the Lee Majors TV series The Fall Guy (1981-86).
