My vote is for the classic Roger Zelanzy series
The Chronicles of Amber. There have been some rumors of making a movie for some time (at one time, the guy who wrote the Battlefield:Earth screenplay was supposed to be writing it, but I seriously hope that was just a 'rumor'.)
I know they were set to begin filming one of my favorite classic series being made into a movie. This from the creator of Tarzan, Edgar Rice Burroughs, and is his Martian Chronicles with John Carter. Specifically, the first book,
A Princess of Mars. I remember back in middle school when I discovered these novels and fell in love with ERB's Mars. Anyway, screenwriter Ehren Kruger (
Arlington Road,
The Ring 1 & 2) wrote a script for the film for Paramount Pictures, but the movie has had alot of setbacks. It has gone thru several directors, including Robert Rodgrigez, Steven Summors, Kerry Conran (his Sky Captain movie made him my fav. pick) and now its been handed to Jon Favreau (after he finishes the Iron Man movie).
