Agree on Resident Evil, not a bad film as a standalone thing but nothing like it could have been. Most videogame adaptations have been real dissapointments, anyway (Mario Bros springs to mind!).
Here's a very controversial one, because it's such an untouchable classic. A British version of Battle Royale, if well made and faithful to the original, could be great. The conditions are right with this climate of people being afraid of the youth, with chavy yobs put on a remote Scottish island along with the rest of their class represting a mix of the many and various youth cultures out there (that group that hung out by the beach could be hip-hop types, we already have those nerRAB who hack into the system and make the bomb, our heroes are of course the indie kiRAB, and we can kill off the Emos quite early!), all battling it out to the death. Nice.
