Some friends and I were discussing possible (but ill-chosen) live-action film versions of video games, and we decided that -if only because it is a prerequisite for the Apocalypse- a live-action version of "Sonic The Hedgehog" must be made!
After some discussion, we concluded that the only logical choice for Dr. Robotnic would of course be Will Farrel. (Although if it were a Dark Knight rip off then Philip Seymour Hoffman would also make sense.) My question is, who would be your choice to slip into a blue costume and play Sonic? Not to mention the actor to portray Tails, Knuckles, etc.
