What book/game/story do you want to see made into a feature-length film?

I would love to see an Assassins Creed movie and I'm surprised no one has made an attempt at a Zelda movie.

EDIT: Check out this Wikipedia Link - films based on video games.

A lot of the popular suggestions like Assassin's Creed, Pokemon, and Metal Gear Solid already have some form of movies made. Not necessarily big-budget Hollywood films though.
