See Bizarro Marty McFly...

Eric Stoltz shot for five weeks on Back to the Future until they recast MJ Fox in the role. CNN has the first glimpse of that footage that will be part of the blu-ray release of the three movies.

wow. that was pretty cool. i wish the clip showed him speaking the lines but I'm guessing I need to pick up the Blu-ray for that...

I love how he says it....
"so luckily I was able to convince the studio to let me re shoot five weeks worth of film"...

Very strange to see someone other than MJF in those settings - Stoltz would have been okay, but most likely the film would not have become such a classic. (IMHO, of course.)
