Sam & Max developer Telltale Games is currently working hard at developing an episodic Back to the Future video game. After months of silence following the game’s announcement, the developer’s released two behind the scenes video clips focusing on Doc and Marty McFly’s characters, respectively.

Marty McFly apparently has a new voice actor, as they couldn’t get Michael J. Fox (the actor who played Marty in the movies) on the game. Fear not, though, as his voice actor is as genuine as Fox himself. Don’t believe me? Check out the clip. It’s scary accurate.
