Will probably be a spoof of all those artsy, foreign, and independent movies that have been really popular. Like Across the Universe, Atonement, Amelie, Little Miss Sunshine, The Last Kiss, Elizabethtown, Juno, La Vie en Rose, The Motorcycle Diaries, Garden State, etcetera, etcetera, etcetera...
Of course, it wasn't so much this last year as it has been the last few years that these indie movies have grown in popularity.
I heard there's gonna be a superhero one, but I also wouldn't be surprised if they did a comic book one. There's been quite a few comic book movies: Ghost World, V for Vendetta...OK those are the only ones that come to my head that don't really have a "superhero" so maybe not
