Here is the list of the Marvel movies, with their domestic gross and the total theatres in their opening: http://www.boxofficemojo.com/franchises/chart/?id=marvelcomics.htm And here is the list of the movies with more theatres, in order: Spider-Man 3Sony 4,324 Iron Man 2Par. 4,390 Spider-Man 2Sony 4,166 Iron ManPar. 4,154 X-Men Origins: WolverineFox 4,102 ThorPar. 3,963 X2: X-Men UnitedFox 3,749 X-Men: The Last StandFox 3,714 X-Men: First ClassFox 3,692 Fantastic FourFox 3,619 X-MenFox 3,112 And if you look at the domestic gross of these movies, the ones with more theatres ended with a better gross. * So the questions are: - Why First Class had less theatres than X2, X3 and Wolverine? - If it would have had 200-400 theatres more, could it have a bigger domestic gross?
