Trivia: Pennsylvania-born actor Don Keefer enjoyed a 60-year-plus career on stage and screen that saw him range freely across character parts and leading roles in both fields. An actor from his youth, he started early playing leads, portraying the title role in The Adventures of Marco Polo for a production of the Child Study Association. He won the Clarence Derwent Award for his early work on Broadway, and spent his early career working alongside the likes of Ethel Barrymore, Helen Hayes, and José Ferrer, and under such directors as Moss Hart, Elia Kazan, and Margaret Webster (including the famed production of Othello starring Paul Robeson). Keefer was a charter member of the Actors' Studio, and originated the role of Bernard, the studious neighbor son-turned-lawyer in Arthur Miller's Death of a Salesman. He was the only actor to remain with the production for its entire Broadway run, and subsequently made his screen debut in 1951 in the movie adaptation of the play produced by Stanley Kramer and directed by Laslo Benedek. From that beginning, he went on to appear in more than 130 movie and television productions, in between theatrical work on both coasts (including a stint at the Theatre Group at UCLA under John Houseman). Highlights of his stage career include a highly acclaimed touring production of Anton Chekhov: The Human Comedy, focusing on the lighter side of Chekhov's work. On screen as on stage, Keefer played a wide variety of parts -- he made a fine villain-turned-neutral in "Winchester Quarantine," an early (and very powerful) episode of Have Gun Will Travel, but was equally good as Ensign Twitchell, the comically (yet tragically) over-eager and officious junior officer in Joseph Pevney's Away All Boats, during this same period. Don Keefer was still working in the late '90s, in movies such as Liar Liar and an episode of Profiler. But amid hundreds of portrayals, Keefer's single most memorable role for most viewers -- other than Bernard in Death of a Salesman -- is almost certainly that of Dan Hollis, the doomed neighbor whose birthday celebration comes to a hideous end (his head popping out of a giant jack-in-the-box) in the 1961 Twilight Zone show "It's a Good Life."

Trivia: Raised in New Orleans' French Quarter, Ray Walston relocated to Houston, where he first set foot on stage in a community production of High Tor. Walston went on to spend six years at the Houston Civic Theater then three more at the Cleveland Playhouse. Moving to New York, he worked as linotype operator at the New York Times before landing small parts in theatrical productions ranging from Maurice Evans' G.I. Hamlet to The Insect Comedy. He won Theater World's "Most Promising Newcomer" award for his portrayal of Mr. Kramer in the original 1948 production of Summer and Smoke. In 1950, he was cast as "big dealer" Luther Billis in the touring and London companies of South Pacific, and it was this that led to a major role in Rodgers & Hammerstein's 1953 Broadway musical Me and Juliet. Two years later, he was cast in his breakthrough role: the puckish Mr. Applegate, aka The Devil, in the Adler-Ross musical smash Damn Yankees. He won a Tony Award for his performance, as well as the opportunity to repeat the role of Applegate in the 1958 film version of Yankees; prior to this triumph, he'd made his film debut in Kiss Them for Me (1957) and recreated Luther Billis in the 1958 filmization of South Pacific. A favorite of director Billy Wilder, Walston was cast as philandering executive Dobisch in The Apartment (1960) and replaced an ailing Peter Sellers as would-be songwriter Orville J. Spooner in Kiss Me, Stupid (1960). Having first appeared on television in 1950, Walston resisted all entreaties to star in a weekly series until he was offered the title role in My Favorite Martian (1963-1966). While he was gratified at the adulation he received for his work on this series (he was particularly pleased by the response from his kiddie fans), Walston later insisted that Martian had "ruined" him in Hollywood, forever typecasting him as an erudite eccentric. By the 1970s, however, Walston was popping up in a wide variety of roles in films like The Sting (1974) and Silver Streak (1977). For the past two decades or so, he has been one of moviedom's favorite curmudgeons, playing such roles as Poopdeck Pappy in Popeye (1980) and officious high school teacher Mr. Hand, who reacts with smoldering rage as his class is interrupted by a pizza delivery in Fast Times at Ridgemont High (1982). He would re-create this last-named role in the weekly sitcom Fast Times (1985), one of several TV assignments of the 1970s and 1980s. In 1995, Ray Walston reacted with schoolboy enthusiasm upon winning an Emmy award for his portrayal of irascible Wisconsin judge Henry Bone on the cult-fave TVer Picket Fences.

Trivia: Prior to his first TV appearance on a 1961 episode of Dobie Gillis, Bill Bixby had been a college student (he dropped out of UC Berkeley in his senior year), a lifeguard, a male model, and a regional stock-company actor. Bixby went on to play small roles in films like Lonely Are the Brave and Irma La Douce, and was featured in the Broadway comedy Under the Yum Yum Tree. In 1963, he graduated to TV stardom with the role of Tim O'Hara on the popular sci-fi sitcom My Favorite Martian. Anxious to change his "wholesome" image after Martian ended its three-year run in 1966, Bixby accepted a small but flashy role as a cowardly villain in the big-screen Western Ride Beyond Vengeance (1966). Like it or not, however, Bixby's future lay in sympathetic parts on episodic television. In each of his subsequent starring series -- The Courtship of Eddie's Father (1969-1972), The Magician (1973), The Incredible Hulk (1978-1982), True Confessions (1984), and Goodnight Beantown (1983) -- Bixby frequently did double-duty as actor and director. He also directed such made-for-TV movies as Barbary Coast (1974), Another Pair of Aces: Three of a Kind (1991), and the Roseanne/Tom Arnold vehicle The Woman Who Loved Elvis (1993). Long one of Hollywood's most eligible bachelors, Bixby finally took the marital plunge with actress Brenda Benet; the union ended tragically when Benet, distraught over the death of her son, Christopher, committed suicide. Bixby's second wife was Judith Kliban, daughter of magazine cartoonist B. Kliban. At the time of his death from prostate cancer, Bill Bixby was principal director of the TV series Blossom.

Trivia: Supporting actress Britton usually played sweet, ditzy blondes.
