The real reason why James Franco and other actors were called back onto the set of Spider-Man 3 to conduct re-shoots is because the film was lacking action and test audiences were not pleased.RUMOR!
Spider-Man 3 actor James Franco has debunked those rumors by informing the public of the fact that the actual test screenings have not even taken place as of yet.
As of September 14th, 2006, he has not yet been back on the set to do any reshoots. "That’s actually much ado about nothing about some test screenings that never took place, and the fact that there wasn’t a lot of action -- that was all boloney. I think I was asked what I was going to be re-shooting and I said 'some action scenes' scenes that were already in it. I actually haven’t gotten back to it yet."
