The movies have absolutely nothing to do with interest in comics. If that were the case then Iron Man, Captain America, and Thor would be 1, 2, and 3 every month.
Hulk's death didn't cause his sales to sky rocket either. Immortal Hulk didn't start off beating Batman. It hasn't been out for just a couple of months. It took great writing and positive word of mouth for it to reach the level of success it has.
