Eric Stoltz as Marty McFly in Back to the Future?

That's exactly what the film's braintrust of Steven Spielberg, Robert Zemeckis and Bob Gale reveal in this clip. Not only was Stoltz the first choice to play McFly, but the team shot five weeks of material with him before deciding to change course and bring in some TV actor named Michael J. Fox.

And now, courtesy of Back to the Future 25th Anniversary Trilogy (out on Blu-ray and DVD Oct. 26) you can see never-before-seen footage of the Caprica actor in the iconic role of the time traveling, DeLorean-driving pal of Doc Brown.

It's kind of like going back to the past....or would that be future? Check it out.
