SEGA and Paramount didn’t have much luck keeping the Sonic Movie 3 and Knuckles TV show secret. First, they’ve had a number of animated scripts that have found their way online, and secondly, it looks like some of Knuckles will take place in Reno, Nevada. Now it has been revealed that the voice behind the controversial Shadow the Hedgehog in the third Sonic film will be none other than Hayden Christensen. Both Sonic Movie 3 and Knuckles will debut later this year.
