Why he rules: If you saw a cool giant machine or floating city in Star Wars episode II or III, there's a good chance it was designed by Ryan Church. His designs for Revenge Of The Sith included a new generation of giant AT-AT walkers with longer legs, giant robot tanks, and a whole gaggle of dinosaur/dragon mounts for the Jedi and soldiers to ride on. And he designed the alien invaders from Steven Spielberg's War Of The Worlds movie, including the fiery concept paintings we've marveled at before.
What he's working on: His in-development credits read like a listing of the most-eagerly-awaited science fiction films of the next few years. They include the vikings-vs-aliens movie Outlander, J.J. Abrams' Star Trek film, James Cameron's 3-D motion capture film Avatar, the animated Escape From Planet Earth, Transformers 2 and John Carter Of Mars.
