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: Before becoming a character actor, Tiger Joe Marsh was a world heavyweight wrestling champion who won his title in 1937. He continued wrestling through 1954 to play opposite Burgess Meredith in a Chicago theatrical production of Teahouse of the August Moon. Later that year, Marsh played a thug in Kazan's classic film On the Waterfront. It was his third movie appearance. Marsh continued working on screen and stage through the late '70s.

Trivia: Dee Hartford was a model turned actress who became the third wife of director Howard Hawks. Born Donna Higgins in 1927, she was the older sister of Eden Hartford, who married Groucho Marx in 1954. Dee Hartford initially achieved fame in the late '40s as a model for Vogue magazine -- a tall brunette with beautifully etched features, she could stop traffic or conversation in a room by entering it, and cut a startling figure in photographs. Hartford chalked up exactly one big-screen credit in her early career, with a role in the 1952 Groucho Marx vehicle A Girl in Every Port, directed by Chester Erskine. She married Hawks -- who was more than 30 years her senior -- the following year, and did no acting during the six years that they were together. The two divorced in 1959, but the director gave her a small uncredited role in his 1965 film Red Line 7000. She had already resumed her acting career by then, on Gunsmoke, Perry Mason, Burke's Law, The Outer Limits ("The Invisibles"), and The Twilight Zone ("Bewitchin' Pool"). Her later work included appearances on Batman, Time Tunnel, Land of the Giants, and Lost in Space. Her work on the latter three series likely came about in part as a result of Hartford's sister Eden's marriage to Groucho Marx -- Marx was one of the primary investors in Irwin Allen's production company, which was responsible for all three programs. Her performance as the android Verda in the 1966 Lost in Space episode "The Android Machine" led to her return in the same role in a sequel, "Revolt of the Androids." Hartford brought an engaging warmth and sincerity to the role of an android who finds herself turning into a human, and is no longer content to allow herself to be treated like a piece of property, with no rights. As a result of "Revolt of the Androids," Hartford became one of the most popular female guest stars in the three-year run of the series. Her last screen role to date was in Michael Campus' 1976 thriller Survival.

Trivia: Diminutive, raspy-voiced German actor Fritz Feld first gained prominence as an assistant to Austrian impresario Max Reinhardt. Feld came to the U.S. in 1923 in the touring company of Reinhardt's The Miracle. Once he reached California, Feld formed the Hollywood Playhouse in partnership with Joseph Schildkraut; here he staged hundreds of productions featuring up-and-coming L.A. talent, including his future wife, actress Virginia Christine. In films on a sporadic basis since the 1920s, Feld began working onscreen regularly around 1936, eventually toting up over 400 movie appearances (not to mention his more than 700 TV stints and 1000-plus radio programs). He was cast as Viennese psychiatrists, Italian duellists, Teutonic movie directors, Russian orchestra leaders, and French maitre d's. It was in 1947's If You Knew Susie that Feld developed his signature "schtick": the sharp "Pop!" sound effect created by smacking his open mouth with the flattened palm of his hand. In the 1960s and 1970s, Feld was a favorite of moviemakers who'd grown up watching his vintage screen appearances; he was virtually a regular at the Disney studios, appeared in many of Jerry Lewis' projects, was given fourth billing in Gene Wilder's The World's Greatest Lover (1977), and was seen in Mel Brooks' Silent Movie (1976) (where his trademarked "Pop!" was conveyed via subtitle) and The History of the World, Part One (1981) (as the head waiter at the Last Supper). Among Fritz Feld's least characteristic screen appearances were his performance as a hearty Northwoods trapper in the 1976 "four-waller" Challenge to Be Free and his poignant cameo as the alcoholic who offers down-and-out Faye Dunaway a match in Barfly (1987).
