I'd like to see a series of short adaptions of HP Lovecraft that are true to the originals. His were short stories, they should be short movies. Done that way, they could be really scary. Something like "Trilogy of Terror" but with all Lovecraft. A whole series of such trilogies would be awesome.
Also, a decent film about really early jazz. I hear a movie is in production called "Bolden", which sounds promising. One on King Oliver would be great too, if done right (which would almost be impossible... very few movie makers would get the music or the ambiance close to correct).
Marty Reisman's "The Money Player".
A decent depiction of Bobby Fischer (also not likely, but some bad ones are certain to be made -- one already has).
