It’s common knowledge that Eric Stoltz was originally cast as Marty McFly in ‘Back to the Future’. After four weeks of shooting the iconic movie, Robert Zemeckis felt as if something wasn’t working and ultimately recast the role with Michael J. Fox.
While all the scenes were reshot, it looks as if a couple of frames featuring Stoltz punching Biff Tannen remained in the final cut. Too Old to Grow Up, the YouTube channel dedicated to all things 80s nostalgia, noticed this and pointed out the part where you can see Stoltz’s fist.
Take a look!
