If I had to guess I'd say no, especially since comics have been continuous stories since the 60's if not sooner (at least the current Marvel Universe). Perhaps there are temporary sales boosts here and there with collected volumes, as the term "graphic novel" has become more and more relevant, but I doubt that monthly sales in general have increased substantially due to the films. Otherwise there wouldn't be a need for constant relaunching of even major titles. At this point the only thing that's keeping the industry afloat is a hardcore fanbase and the revenue generated from the films themselves. I think the industry is still damaged from the unsustainable overproduction of the 1990's that destroyed collectability. That and the advent of technology like video and computer games that attract the attention of young kids. Perhaps the fact that comics are tailored more to teenagers and adults hurts.
