Just imagine if someone other than Lucas was allowed to make a Star Wars film. I think it would be awesome. Just consider what's happened with the Batman and Star Trek franchises. Seriously, I think if they could find the right filmmaker, they could make some damn good Star Wars films. But I doubt Lucas would allow it.
If they did make one, I'd love to see a film that takes place after Revenge of the Sith but well before Star Wars. There's 20 years worth of stuff that happened between those films!
