And that's a good thing. GameTrailers has put up a couple behind-the-scenes vids of Telltale Games' upcoming Back to the Future game, and the guy they got to voice Marty McFly does a virtuoso Michael J. Fox.

It's one thing to do an impersonation, it's another to apply that voice to real acting. It's just a few clips, but A.J. LoCascio, McFly's voice, really does seem to pull it off. Quite a serendipitous casting.

Here's another video, released Friday, featuring Christopher Lloyd and the game's creative staff setting up the premise of Telltale's game.
