Fallout could work well as a movie.
There are 113 confirmed, canon vaults, scattered about the US. There's no mention that this is an absolute number and not all the vaults that are confirmed have been given a back-story/purpose. There's plenty of room to move about and make an original script within the Fallout Universe that doesn't totally balls up the games thus far.
The setting would probably be New York, the only US city marketable to filthy foreigners that hasn't already had a Fallout set in it. The plot would be fairly linear, probably your mutants Vs humans scenario, with our plucky young Vault Dweller being forced to emerge, due to a robot uprising in the vault, at just the right moment to shift the balance in power to the humans, who then proceed to wipe out the filthy mutants, before vanishing off into the wastes after blasting half the flesh off the overseer when he returns to his Vault with really big guns to blast the robots new service panels, discovering that the overseer is totally a robot.
Yeah, sounds shit now, but give it a few exploding cars, giant robots, plasma rifles and super mutants and the movie going public will gladly fork over their download time to pirate the thing.
