Full-length Simpsons Movie

Nancy Cartwright, who is the voice of Bart on The Simpsons, says preliminary production has started on a movie based on the Fox hit TV show. Animation and production is expected to take two years before the movie can be released.

"They are working on hammering out a script, but there's no title or production date or release date," studio spokeswoman Antonia Coffman told E! Online Wednesday.

"We always wanted the show to end first but it just keeps going. Now they've worked out a team to simultaneously do [both the film and show]."
