Michael J.Fox is returning to the franchise we know him for best… the “Back to the Future” series. Fox isn’t reprising the role of skateboarding time-traveler Marty McFly for a new film, but for the popular Telltale video game series – in particular, for the fifth and final episode.

The games, which have featured the voices of original “Back to the Future” cast members Christopher Lloyd and Claudia Wells,have Fox sound-a-like AJ LoCascio voicing Marty McFly; needless to say, Telltale weren’t going to fire LoCascio and bring in Fox to revoice the character, instead they’ve cast Fox as one of McFly’s ancestors (you’ll recall Fox played Marty’s way-back-when ancestors in “Back to the Future Part III”) for the episode. I’m sure it was only a couple of hours work for Fox – and rightfully so; he’s not a well man – but great to have him involved in this all the same.

Here’s a behind-the-scenes promo featuring Fox’s cameo :
