Most everyone who went to high school in Livingston, NJ, with Newark-born Jason Alexander knew that the lad was destined to become a major actor. Though inclined to stoutness -- and baldness -- from age 16 onward, Alexander had such a commanding stage presence that he was invariably cast as the star in school plays, in roles ranging from romantic leads to elderly character parts.
While attending Boston University, the 20-year-old Alexander was cast in the lead of the Stephen Sondheim Broadway musical {+Merrily We Roll Along}, which might have made him an overnight star had it not closed almost as soon as it opened. Alexander's first film role was in 1981's The Burning; that same year he made his TV-movie bow in Senior Trip. By 1989, Alexander had two major industry awards to his credit: the Tony and Grammy, both for his participation in {+Jerome Robbins' Broadway}. In 1990, he was cast as clueless loser George Costanza in the popular sitcom Seinfeld (the character was allegedly based on series co-creator Larry David). And in 1994, his voice could be heard each week on the USA cable network as the web-footed, sex-obsessed private eye hero of the animated cartoon series Duckman. Though still best-known for his portrayal of George Costanza, Alexander's feature film career picked up speed during the '90s as both a character actor in major comedies such as Dunston Checks In and a voice-over artist on such animated Disney features as Aladdin and The Hunchback of Notre Dame. In 1997, he played a more dramatic role as an AIDS-afflicted drag queen who finds romance in Love! Valour! Compassion! (1997). After a disappointing blink-and-you-miss-it comeback to the small screen as a self-help guru in Bob Patterson, Alexander leapt back to the big screen opposite Jack Black in the Farrelly brothers' Shallow Hal. ~ Hal Erickson, All Movie Guide.
