I'd be up for Elric or Fafhrd and Gray Mouser. More Discworld on the screen? Sure, sign me up!
As for Dune, I also didn't completely hate the movie, I own the theatrical and extended cuts. I am, however, not a big fan of the continual VO by the characters. My wife loves it when I watch the film and scream at the screen, "WHY CAN I HEAR YOUR THOUGHTS?!!?" Didn't mind this as much in original Blade Runner, which is often criticized for the same reason. It was like Deckard was reading his police report and I could take it or leave it, but I sure did hate it in Dune!
