I know this list seems all over the place, but I wanted to find some local (Buffalo and Rochester), some not so local (Atlanta), some internationally famous (Siggraph and Annecy), and some genre special (can you actually believe there is a "Drunken Zombie Film Festival?" And it's famous for finding distributors for the movies screened there!).
Making this list has helped to pump me up (especially finding the zombie film festivals). I think I might just actually get this thing finished after all.
