Jason Alexander

Jason Alexander may have split his career between Tony Award-winning musical performances and playing the voice of many animated characters, but mainstream television viewers were hard-pressed to remember him as anyone other than the worrisome, bespectacled sidekick of Jerry Seinfeld on the landmark 1990s sitcom, "Seinfeld" (NBC, 1989-98). The plum role of over-the-top George Costanza was indeed a superb showcase for Alexander's physical comedy and punch line timing, but attempts at headlining his own sitcom with "Bob Patterson" (ABC, 2001) and "Listen Up" (CBS, 2004-05), were short-lived. Like his fellow "Seinfeld" cast members, he found it nearly impossible to recreate the once-in-a-lifetime critical and popular success of his breakout series, but Alexander remained steadily employed as a television and theater director, stage actor, and regularly resurfaced in guest TV roles as nebbishy, neurotic types akin to the character that made him famous.
