Michael J. Fox Goes Back To 'Back To The Future' In New Teaser Trailer

In case the just-released footage of Eric Stoltz as the original Marty McFly wasn't enough to get you screaming "1.21 gigawatts!," here's some more "Back to the Future" awesomeness: a newly shot "Back to the Future" teaser trailer starring the man who replaced Stoltz behind the wheel of the time-traveling DeLorean, Michael J. Fox.

The new clip was shot to hype the "Back to the Future" reunion taking place at Spike's 2010 Scream Awards on October 19. Cast members Fox, Lea Thompson (Marty's mom Lorraine) and Elizabeth Shue (Marty's girlfriend Jennifer... from "Back to the Future: Part II" and "Part III," but not the original) will gather on stage to celebrate the original film's 25th anniversary.

The new teaser is basically a shot-for-shot remake of the film's original 1985 trailer... but with one very big difference at the end... which you can check out for yourself.

Seeing Fox in the Marty getup after all this time is enough to make one nostalgic for the film. Luckily the "Back to the Future" Trilogy 25th Anniversary collection is traveling onto Blu-ray and DVD October 26. Until then, cross your fingers that Crispin Glover's George McFly, Christopher Lloyd's Doc Brown and Tom Wilson's Biff Tanen show up for the Scream Awards. A reunion without those guys might make us want to make like a tree and get the hell outta there.

What do you think of the new "Back to the Future" teaser trailer? Are you psyched for the movie to special edition on Blu-ray and DVD?
