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 early on, short, pugnacious American actor Gerald S. O'Loughlin dreamed of becoming a lawyer, the prohibitive cost of law school forced him to steer toward engineering as a career. O'Loughlin was deflected from this ambition by an increasing interest in the theatre. After a long stint with the Marines, O'Loughlin used his GI Bill money to finance his participation at the Neighborhood Playhouse in New York. Working steadily on stage and in live TV drama, O'Loughlin made an inauspicious debut as the romantic lead in the Manhattan-filmed turkey Lovers and Lollipops (1956); one year later, he was shown to better advantage re-creating his stage role in the filmization of Michael Gazzo's play A Hatful of Rain (1957). For many children of the '70s, Gerald O'Loughlin will always be the tough-but-tender Lt. Ryker on the long-running cop series The Rookies. Even in his subsequent TV series assignments (Automan [1983-1984], Our House [1986]) one half expected O'Loughlin to drop character and start barking out "Hey! Danko." Gerald O'Loughlin was married to casting director Meryl Abeles.

Trivia: Lead actor, onscreen from the '60s.

Trivia: Most 1970s-era couch potatoes first saw lissome leading lady Christine Belford when she portrayed insurance investigator Carlie Kirkland during the second season (1973-74) of the George Peppard TV series Banacek. It would not be the last time that Christine would appear as a series regular: In chronological order, she played Aunt Emily in Married: The First Year (1979); Jackie Willow, wife of Richard Masur in Empire (1984); and sheriff Maggie Randall on Outlaws (1987). She also co-hosted (with Steve Edwards) the 1983 daytime-magazine series Personal & Confidential. Christine Belford's feature-length films include Pocket Money (1972), The Groundstar Conspiracy (1972), and the made-for-TV Kenny Rogers as the Gambler (1980).

Trivia: Diminutive American actor Phil Leeds has been trafficking in comedy character roles for well over 50 years. When not showing up on Broadway or on tour, Leeds has been a regular visitor to television. He was seen on a weekly basis as an ensemble player on the DuMont Network's 1950 variety series Front Row Center; as Moscow apartment dweller Vladimir in Ivan the Terrible (1976); as delicatessen habitue Lou Gold in Singer and Sons (1990); and as "The Kid," a 75-year-old con man, in Double Rush (1995). A relative latecomer to films, Phil Leeds has made up for lost time with a steady stream of select character roles; notably his poignantly amusing cameo as the long-dead husband in the hospital emergency room in Ghost (1990), eagerly anticipating a reunion with his about-to-die widow.
