Edward Norton is reportedly in disagreement with Marvel Studios over the editing of his new movie The Incredible Hulk.

According to Deadline Hollywood Daily, "there's a lot of posturing going on between Edward's camp and Marvel over how you edit the final version".

Norton agreed to play the role of Bruce Banner, a scientist who transforms into the giant green Hulk, in the comic book sequel on the grounds that he was allowed to rewrite Zak Penn's script.

However, an insider claimed that Marvel is blocking Norton from the editing process: "There's a problem. Marvel won't listen to Norton about the cut."

Norton had previously clashed with director Tony Kaye on American History X. Kaye was eventually fired from the movie and Norton cut a new version of the film.

"Never let an actor write a script," a source added. "Marvel made a mistake letting the wolf into the hen house."

Norton is allegedly negotiating with Marvel's David Maisel and Kevin Feige and director Louis Leterrier in an attempt to resolve the dispute.

A source said: "At this stage you always have discussions about what's in the film and what's not going to be in the film. Everyone's very passionate, and Edward is very opinionated."
