That's hi-larious. Most movies are already based on comics, tv shows, and books, because Hollywood has no more fresh ideas. Or if they do, they're unwilling to take risks on actually going forth with something potentially good and original. All they've got now are adaptations, sequels, and remakes. REMAKES!!! The epitomy of filmmaking laziness. b-(
Tell that to Pixar. Or DreamWorks Animation. Or LucasFilm. Or Aardman Animation. Or...
Anyway "Hollywood" is not the be all and end all of movies.
