The actor reprises his role as Batman/Bruce Wayne for the third time in The Dark Knight Rises, and his co-star Matthew Modine hinted that he may not be sorry to leave the role behind.
"I think Christian may have had enough," Modine told E Online. "You don't want to become a sort of parody of what it is."
Modine went on to compare Bale's role to Sean Connery's tenure as James Bond, saying: "There was a point when you wished that Sean Connery would have stopped.
"He was just getting too old and the toupees were getting too big. They're going to go out winning."
Bale has stated that he would be open to doing further Batman films with Nolan.
His ex-publicist Harrison Cheung has made several claims about Bale in a new tell-all book, including a reported rivalry with Leonardo DiCaprio.
The Dark Knight Rises is released on July 20. Watch a trailer below:
