Bale open to another 'Batman' movie

Christian Bale would "love the challenge" of playing Batman for a fourth time.

The actor portrays the Caped Crusader and his alter ego Bruce Wayne for the third time in 'The Dark Knight Rises' and though it is expected to be the final film in director Christopher Nolan's series, the 38-year-old star hasn't ruled out returning to the character again in the future.
