The 51-year-old actor says he believes his movie career has been a "complete failure."

"I'll tell you why," he says. "The goal of moviemaking is to star in a film where your performance drives the film, and the film is either a soaring critical or commercial success, and I never had that."

Baldwin says he also thought about giving up acting in 2007, after a voicemail of him angrily railing at his daughter went public.
