Trivia: Born Leonard Rosenberg, Randall moved to New York at age 19 and studied theater with Sanford Meisner and at the Neighborhood Playhouse. His stage debut was in The Circle of Chalk (1941). From 1942-46 he served with the U.S. Army, following which he acted on radio and TV. He began appearing onscreen in 1957 and was a fairly busy film actor through the mid '60s. He is best known for his work on TV, particularly for his portrayal of fastidious Felix Unger on the sitcom "The Odd Couple." He also starred or costarred in the series "One Man's Family," "Mr. Peepers," "The Tony Randall Show," and "Love, Sidney." He frequently appears on TV talk shows, where he is witty, erudite, and urbane. In 1991 he created the National Actors Theater, a repertory company; its purpose is to bring star-filled classic plays to broad-based audiences at low prices.

Trivia: Commenting on his notorious on-set irascibility in 1977, Jack Klugman replied that he was merely "taking Peter Falk lessons from Robert Blake," invoking the names of two other allegedly hard-to-please TV stars. Klugman grew up in Philadelphia, and after taking in a 1939 performance by New York's Group Theatre, Klugman decided that an actor's life was right up his alley. He majored in drama at Carnegie Tech and studied acting at the American Theatre Wing before making his (non-salaried) 1949 stage-debut at the Equity Library Theater. While sharing a New York flat with fellow hopeful Charles Bronson, Klugman took several "grub" jobs to survive, at one point selling his blood for $85 a pint. During television's so-called Golden Age, Klugman appeared in as many as 400 TV shows. He made his film debut in 1956, and three years later co-starred with Ethel Merman in the original Broadway production of Gypsy. In 1964, Klugman won the first of his Emmy awards for his performance in "Blacklist," an episode of the TV series The Defenders; that same year, he starred in his first sitcom, the 13-week wonder Harris Against the World. Far more successful was his next TV series, The Odd Couple, which ran from 1970 through 1974; Klugman won two Emmies for his portrayal of incorrigible slob Oscar Madison (he'd previously essayed the role when he replaced Walter Matthau in the original Broadway production of the Neil Simon play). It was during Odd Couple's run that the network "suits" got their first real taste of Klugman's savage indignation, when he and co-star Tony Randall threatened to boycott the show unless the idiotic laughtrack was removed (Klugman and Randall won that round; from 1971 onward, Odd Couple was filmed before a live audience). It was but a foretaste of things to come during Klugman's six-year (1977-83) reign as star of Quincy, M.E.. Popular though Klugman was in the role of the crusading, speechifying LA County Coroner's Office medical examiner R. Quincy, he hardly endeared himself to the producers when he vented his anger against their creative decisions in the pages of TV Guide. Nor was he warmly regarded by the Writer's Guild when he complained about the paucity of high-quality scripts (he wrote several Quincy episodes himself, with mixed results). After Quincy's cancellation, Klugman starred in the Broadway play I'm Not Rappaport and co-starred with John Stamos in the 1986 sitcom You Again?. The future of Klugman's career -- and his future, period -- was sorely threatened when he underwent throat surgery in 1989. He'd been diagnosed with cancer of the larynx as early as 1974, but at that time was able to continue working after a small growth was removed. For several years after the 1989 operation, Klugman was unable to speak, though he soon regained this ability. He continued working through 2011, and died the following year at age 90.

Trivia: Though frequently cast in Jewish roles, actor Michael Constantine was actually of Greek extraction. The son of a steel worker, Constantine studied acting with such prominent mentors as Howard DaSilva. The prematurely balding Constantine was playing character roles on and off Broadway in his mid-twenties (he was the Darrow counterpart in the original production of Compulsion), supplementing his income as a night watchman and shooting-gallery barker. In 1959, slightly weary of being ignored by callous Broadway producers and casting directors, Constantine appeared in his first film, The Last Mile (1959), thereby launching a cinematic career that has endured into the mid-1990s. Michael Constantine is perhaps best known for his extensive TV work, notably his four-season (1969-1974) stint as long-suffering high school principal Seymour Kaufman on Room 222 and his starring appearance as night-court magistrate Matthew J. Sirota on the brief 1976 sitcom Sirota's Court.

Trivia: An alumnus of the Indiana University Law School, Herbert Vigran gave up the legal world to become an actor. Making his 1935 film debut in Vagabond Lady, Vigran had a few lean months after his first flurry of Hollywood activity, but began getting stage work in New York on the basis of a portfolio of photos showing him sharing scenes with several well-known movie actors (never mentioning that most of his film roles were bit parts). After his first Broadway success in Having Wonderful Time, Vigran returned to L.A., accepting small parts in movies while keeping busy with plenty of lucrative radio work; among his hundreds of radio assignments was the title character on the wartime sitcom "The Sad Sack." In films, the harsh-voiced, heavily eyebrowed Vigran could usually be seen as brash reporters and Runyon-esque hoodlums; his favorite role was the rumpled private eye in the 1954 Dick Powell/Debbie Reynolds comedy Susan Slept Here. During the 1950s, Vigran was most active in TV, essaying half a dozen bad guy roles on the Superman series and appearing regularly as Monte the Bartender on the Dante's Inferno episodes of the anthology series Four Star Playhouse. In the early '70s, Herb Vigran found time during his hectic movie and voice-over schedule to play the recurring role of Judge Brooker on Gunsmoke.

Trivia: To younger generations, the slightly diminutive and balding American character actor Richard Stahl was probably best known as Howard Miller, the deadpan, stone-faced chef (and indifferent receptor of Marian Mercer's affections) on the long-running syndicated sitcom It's a Living. Stahl inherited the position from fellow supporting player Bert Remsen, and sustained it for four seasons, until the program wrapped in September 1989. But Stahl's visage graced a much broader spectrum of films and television shows than his behind-the-counter presence at the Above the Top restaurant -- and if viewers have trouble making a list, this is only a reflection on Stahl's ability to blend in successfully with fellow cast members and settings. Such is the essence of a gifted character player. Stahl made his first bow in 1966, as Steve Parsons on the "Dear Sally Rogers" episode of The Dick Van Dyke Show (its final season). He subsequently became a mainstay on the television airwaves, and his resumé reads like a laundry list of '70s and '80s hit prime time series, including but not limited to: That Girl, The Partridge Family, Love American Style, Bonanza, Columbo, All in the Family, Good Times, The Odd Couple, Maude, Happy Days, The Facts of Life, Murder, She Wrote, Hill Street Blues, and a handful of particularly memorable turns on Newhart. He reinforced his small-screen presence (and audience familiarity) with feature film appearances in such motion pictures as Five Easy Pieces (1970), High Anxiety (1977), The Flamingo Kid (1984), The American President (1995), and The Ghosts of Mississippi (1996). Stahl landed his last role with a bit part in Garry Marshall's 1999 flop, The Other Sister. He spent his final seven years in retirement, battling Parkinson's Disease, and eventually succumbed to the illness on June 18, 2006. Stahl was seventy-four.
