Hollywood Elsewhere says that Hood left the set for a brief period of time only to return and see a large set for the film had been completely repainted to make it brighter and give it less of a dark and somber vibe. I would think that with the success of THE DARK KNIGHT and the Comic-Con footage (which featured Wolverine telling Sabretooth he was going to rip his “goddamn head” off), that they might opt for a darker feel.
Now keep in mind that rumors of turmoil between Fox and Hood have been swirling for some time now and this is just one of the first leaked incidents to support those rumors. I’m sure as the project continues through editing and post-production we’ll hear even more. Hopefully Fox will invite a few select journalists to some kind of pow-wow with Hood (perhaps in the edit bay) to help straighten all this out…
