Paul Reiser is probably best known for his work in stand-up comedy and his starring role on the long-running sitcom Mad About You, which helped launch Helen Hunt’s career. Reiser’s first major film role was in the 1982 movie Diner, which co-starred Kevin Bacon, Steve Guttenberg and Mickey Rourke. Reiser also appeared in Beverly Hills Cop and Beverly Hills Cop II, but his most memorable role in my eyes was definitely as Carter Burke in Aliens. Other notable Paul Reiser credits include Crazy People, Bye Bye Love, and Curb Your Enthusiasm. He also appeared in the documentary The Aristocrats, telling one of the less filthy versions of the infamous joke. Paul Reiser turns 56 today.
