Back to the Future - Eric Stoltz as Marty McFly Footage?

[Sussudio]

Anyone ever seen this? I've searched all over the internet and haven't been able to find them. I know there was talk of the scenes being released on the DVDs but the studio decided they didn't want to "embarrass" Stoltz (hence why none of it is probably online anywhere) and the footage has long since been forgotten. Even though MJ Fox was perfect casting, it would still be interesting to see Stoltz' performance..

Here's a Wiki excerpt if you don't know what I'm referring to:

[Eric Stoltz was initially cast as Marty McFly since first choice Michael J Fox had scheduling conflicts]. Four weeks into filming, Zemeckis decided Stoltz was miscast. Although he and Spielberg realized reshooting the film would add $3 million to the $14 million budget, they decided to recast. Spielberg explained Zemeckis felt Stoltz was too humorless and gave a "terrifically dramatic performance". Gale further explained they felt Stoltz was simply acting out the role, whereas Fox himself had a personality like Marty McFly. He felt Stoltz was uncomfortable riding a skateboard, whereas Fox was not. Stoltz confessed to director Peter Bogdanovich during a phone call, two weeks into the shoot, that he was unsure of Zemeckis and Gale's direction, and concurred that he was wrong for the role.
