A power-struggle seems to be brewing on the set of X-Men Origins: Wolverine, if rumor is to be believed. According to Hollywood Elsewhere there are differences of opinion over the tone of the film between Gavin Hood, who is directing the film, and Fox co-chairman and CEO Tom Rothman.

The struggle seems to center over whether or not the film should be dark, somber and gritty (as Hood would prefer) or if the film should be a little brighter and lighter, in order to draw a wider audience, which seems to be Rothman's view.

Specifically, the latest blow-up between the two involves the rumored repainting of one of the X-Men Origins: Wolverine sets, which had been repainted under Rothman's orders while Hood was away from the set for a few days.

We'll see how this rumored friction between the director and the Fox co-chairman will affect the final fate of X-Men Origins: Wolverine when the film hits theatres in May 2009.
