'Michael J. Fox Show': See the 'Back to the Future' Reunion (Exclusive Photos)

The Michael J. Fox Show Christopher Lloyd EXCLUSIVE - H 2013
Great Scott! NBC's The Michael J. Fox Show is going Back to the Future in the spring when guest star Christopher Lloyd will reunite with the former Marty McFly -- and The Hollywood Reporter has the exclusive first look.
Lloyd, who played bumbling genius Dr. Emmett Brown in the three Universal features, will guest-star as the eccentric principal at the high school where Annie (Betsy Brandt) teaches and will go toe-to-toe with Mike (Fox).
From the early preview, it looks like the old friends could wind up working side by side in what appears to be a wicked game of laser tag. Check out the first-look photos above and below and hit the comments with your thoughts. The series airs Thursdays at 9:30 p.m. on NBC. A formal air date for Lloyd's appearance has not yet been announced.
