RADA alumnus Donald Moffat made his London stage debut in 1954, playing the First Murderer in MacBeth. On stage, the wiry, angular Moffat excelled in the plays of Ibsen and Moliere; on screen, he has since carved his niche in eccentric, unpredictable roles. He has also sparkled in authoritative characterizations, both bombastic (a tantrum-tossing LBJ in 1981's The Right Stuff, a fascistic Colonel Ruppert in the 1991 TV movie Babe Ruth) and cool-headed (the fictional U.S. president in 1993's A Clear and Present Danger, Kennedy in-law Hugh Auchincloss in the 1982 video presentation Jacqueline Bouvier Kennedy). In addition, Moffat has brightened many a Robert Altman production, most prominently as the ubiquitous bike-riding tax collector in Popeye (1980). Donald Moffat's TV-series resumé includes such roles as an immigrant Scandinavian minister in The New Land (1974), a lovable android in Logan's Run (1977), and all-knowing Dr. Marcus Polk on the ABC daytimer One Life to Live.
