Yesterday we told you that the first trailer "The Incredible Hulk" starring Ed Norton was debuting Wednesday night on MTV. We also told you that it was strange that it took this long to get our first glimpse of one of the summer's most anticipated movies. Now we know what may be causing the delay.

Deadline Hollywood Daily is reporting that Norton and Marvel Studios are battling over final cut on the film.

That's right, Ed Norton -- star/producer/writer of the movie, NOT the director Louis Leterrier, is locking horns with the Marvel folks over final editing. Apparently Norton was promised all kinds of access and control when he was brought onboard for the reboot of the Hulk franchise. Now he's putting his foot down over how the final version of the film should turn out.

The article quotes several sources, some who say Marvel should never have let the star of its movie write it. Another says Norton is genuinely passionate about the film and he has a strong vision for it.

Hey, sometimes a little creative conflict is good. Many a good film has been found or lost in the edit room. I just hope whatever differences both sides have are worked out in time to make this a better Hulk movie than the first one.

"The Incredible Hulk" opens June 13. Here's the promo for the trailer:
