Fringe is going Back to the Future.
The Fox drama has booked veteran actor Christopher Lloyd for an appearance on the season's 10th episode. Look for the man forever known as Doc Brown to play Walter's musical hero, reports TV Guide.
"We all know how much Walter loves music, right? Well, this fellow was one of his icons," said John Noble of Lloyd's character.
The actor last showed up on the small screen on an episode of Chuck in May.
