With principal photography on the "Fantastic Four" film about to wrap, Cinescape now reports that the entire third act of the film has undergone extensive changes as a result of Pixar's CGI family film "The Incredibles". Seems after seeing the stretching effects of Elastigirl, the final battle sequence of FF needed to be beefed up, especially the similarly stretchable Mister Fantastic (Ioan Gruffudd).

20th Century Fox apparently stepped up to the plate and coughed up more dough, anywhere up to an alleged $20 million in fact so Mister Fantastic could have more screen time to stretch across and some of the other characters may get some more action as well. On top of this, the third act has had to undergo a major rewrite. Writers and producers have been working overtime all through November and December as they thought about ways to better build up the film's final battles and the resolution.

This has lead to almost daily script changes in order to distance the FF ending from that of "The Incredibles". The changes aren't expected to affect the release date however with things still proceeding on course for a July 4th holiday weekend opening.

Thanks to 'Patrick'.
