London (ANI): While the Batman movie The Dark Knight was a box office hit, a much expected sequel to it may never be made. The reason for the movie not having a sequel is because director, Christopher Nolan, does not think he can do it without late Aussie actor Heath Ledger.

When Ledger passed away, it had looked like American actor Aaron Eckhart would be the new villain, but he has revealed that Nolan has been having second thoughts about it. "Chris hasn't said he's going to make a third film. I think he wants to make other movies," News of the World quoted Eckhart as saying.
