Alec Baldwin's commanding onscreen presence won him big screen acclaim in "The Hunt for Red October" (1990), "Glengarry Glen Ross" (1992), "The Cooler" (2003) and "The Departed" (2006). Offscreen, however, his outspoken liberal politics and his impatience with the Hollywood system initially limited the gifted actor's leading man potential at its youthful peak. His tempestuous courtship and marriage to actress Kim Basinger - coupled with the view by many in the industry that both were "difficult" - only helped dull the luster of a promising career as sexy movie hero. Once his profile lowered, Baldwin divided his time between character film roles of varying size, New York stage productions, and political activism until the sitcom "30 Rock" (NBC, 2006-2013) offered him an ideal outlet for his cocky, breezy charm. After repeatedly threatening to quit showbiz, Baldwin suddenly found himself with numerous acting awards and watched as his former leading man image - with the help of many classic hosting appearances on "Saturday Night Live" (NBC, 1975- ) - morphed him into that of a peerless comic actor. For years, he had shown hints of comedic timing few actors possessed, but between his fearless "SNL" appearances and the revered role of network exec Jack Donaghy on "30 Rock," even established comedians were reluctant to get in the ring with Baldwin, who could more than hold his own.
