Christopher Nolan is reportedly considering using previously unseen footage of Heath Ledger in the new Batman movie.

The director confirmed he would be helming the third instalment of the popular franchise, entitled The Dark Knight Rises, earlier this year. He called the movie "inevitable", and admitted he is excited to start work on it.

Late actor Heath Ledger won a post-humous Oscar for his portrayal of the Joker in 2008 film The Dark Knight, and it has been suggested Christopher is keen to pay tribute to him.

"The idea is to use these fragments of cut scenes and use CGI to have The Joker appear one last time," a source explained. "Chris wants some continuity between movies and for the franchise to pay tribute to Heath and his portrayal of the Joker."

It is thought only a snippet of footage will be used, although the plan is only in the early stages at the moment. If it goes ahead it is likely to be a hit with fans and industry professionals alike, as Heath's portrayal of the Joker has gone down in film history as one of the most intense depictions of a character ever seen.

"It would only be a fleeting moment in the movie and would only be included with the full consent of Heath's family," the source added.

Heath died in January 2008 of a prescription drug overdose.
