Nancy Cartwright's work is widely heard and well loved, but not many people know it's her. She's the voice of Bart Simpson on TV's The Simpsons — and in the long-awaited feature film that hits theaters this week.

Al Jean knows Marge, Homer, Bart and the gang better than almost anyone. He's executive producer and writer for The Simpsons, and he's been with the show since it began. The new Simpsons movie, he's been heard to say, is about "what happens when a man doesn't listen to his wife."

Before The Simpsons, Jean worked on TV's A.L.F. and It's Garry Shandling's Show.

German filmmaker Werner Herzog discusses his new film Rescue Dawn, a Hollywood adaptation of his 1997 documentary Little Dieter Needs to Fly. Both the movie and the documentary are based on the true story of Dieter Dengler, the only U.S. pilot to successfully escape from a North Vietnamese-controlled prison.
