This list over at Gamma Squad is pretty good.  “The Rocketeer” was an amazing movie, and I’d love to see what could be done with the concept with a huge budget.  Something I’d never considered before, though: Dick Tracy.  Yes.  Get some weird, dark-minded director, a Nicolas Winding Refn or some other David Lynch-type to really bring out the bizarre in the thing.  That could really work.  Full list here.
