A while back I wrote about lost performances, and referenced the fact that Eric Stoltz was the original Marty McFly. After several weeks of shooting, the film’s creators decided that they’d made a casting mistake - ultimately giving the role to Michael J. Fox.

Part of the footage, along with commentary from Director Robert Zemeckis and Producer Steven Spielberg will be included on the film’s upcoming 25th Anniversary DVD. Have a look (you'll have to watch an ad first):
