I'm somewhat excited about the upcoming Batman film -- not as much anticipation as I had for Avengers, but still want to see it -- but I'm kind of getting tired of the megablockbuster aspect of comic book movies.
You know what would be really cool? Take $30 million of Warner Bros money and offer it to half a dozen or more filmmakers to make 10-20 minute short films about Batman (or Gotham City). It would be the equivalent of the Batman: Black and White comics anthology but on film. (Those are 1-5 page stories by leading comic book writers and artists, many of whom would never otherwise be hired to write or draw a "regular" Batman comic.) Share the same actors for the same characters -- or don't.
Instead of taking a comic book and painting it on screen with CGI, use filmmaking ingenuity to make cool shorts. You could even tick off the genres: horror movie, detective movie, heist movie (starring Catwoman?), street level human interest movie, a film strictly from Alfred's POV, a story from Batman's retirement.
All the films would be different styles. Imagine a Tarantino, or John Woo Batman. Or a Michael Mann Batman. A Lena Dunham Gotham city girl obsessed with Batman? A Wes Anderson Alfred cleans up the Batcave ( through stop-motion animation?)!
Do it with a relatively low budget, shoot them down and dirty, and release the best 90 minutes in theaters, include the rest on DVD. Will it make a billion dollars? No, but a profit would be guaranteed.
Couldn't do worse than Green Lantern.
