Pretty funny reading back through this thread, considering some of the things that were going to happen but didn't (Buffy reboot, Dark Tower) and things people wanted to see that actually did (more direct adaptations of comic book storylines, 3001).
Then there's stuff like Hyperion, which Scorsese and DiCaprio were talking about years ago but nothing ever came of it. Last I heard was that Bradley Cooper (yup) was taking a crack at the script but that was a couple years ago.
As for Dune, well, I'm surprised there hasn't been any talk of getting James McAvoy back for a God Emperor of Dune miniseries.
I'd also like to see more original, not-based-on-anything movies as someone in the thread suggested.
