An Eric Stoltz Back to the Future role almost happened when he was cast as Marty McFly, the role that eventually went to Michael J Fox. Stoltz’s time playing Marty McFly was cut short, partially due to his interpretation of the Back to the Future ending as a tragedy. Back to the Future's ending is bleak, and the movie ends with Marty McFly returning to 1985 from his trip to 1955. Along the way, Marty adjusted his own future, returning to a version of 1985 where his family members were better versions of themselves. The Eric Stoltz Back to the Future interpretation was that this was a tragic ending, which wasn't how director Robert Zemeckis saw it.

Before Michael J. Fox was cast in the iconic role of Marty McFly, the Eric Stoltz Back to the Future character began the movie’s production. Stoltz was fired from Back to the Future — replaced by Fox after the creators opted to go another route with Marty’s character approach. One of the reasons Stoltz was let go was because of the intense way he interpreted and portrayed Marty. In an interview for Netflix’s The Movies That Made Us, the Back to the Future creators said how his depressing reading of Back to the Future’s ending was part of what lost him the role. Stoltz’s interpretation was Marty returns to the future with an entirely new life, making him an outsider in his family.

Why Back To The Future's Ending Is Secretly Heartbreaking

Marty is essentially a stranger to his own life when he returns home; he knows that his family isn’t who they were before, and while he can put the pieces together, he doesn’t know what his new life has been like for the past 17 years. The life Marty knew before Doc Brown took him back to 1955 was sad — his father was a timid push-over, his mother a crass alcoholic. After Marty used time travel to return, Back To The Future's McFly family was loving and connected, all of them thriving and confident. Marty's life appears better now that he fixed his parents’ relationship in the 1950s, but he never got to experience a better upbringing in the Back to the Future ending.

Not only that, but Marty's time would be short living with this new version of his parents because he's almost out of high school. Considering that his life is altogether unrecognizable, there are no guarantees he would have ever met Doc or Jennifer, nor would he have turned out to be the same chipper Marty McFly. Essentially the Back to the Future ending is depressing because it has Marty's time-traveling adventure end by having effectively removed all the family that he loved. He makes a "better" life for his family, but he never got to experience a second of it. In this way, Eric Stoltz's reading is right, and Back to the Future's ending is sad.

What If Eric Stoltz Had Played Marty McFly In Back To The Future

Eric Stoltz as Marty McFly in Back to the Future.

It's hard to imagine Marty McFly without Michael J. Fox, but Eric Stoltz ended up shooting a fair amount of footage as the character before he was fired. And since Stoltz always saw the Back to the Future ending as bleak, the trilogy would have played out in a very different way had he remained in the role. For starters, Stoltz's Marty McFly was more serious and affected. He would've taken Doc's near-death experience with the Libyans more to heart, and that depression would have driven his actions moving forward. Marty Mcfly's "chicken" trigger would have held more weight considering it's the word that caused a negative outcome for him back in 1955.

In an Eric Stoltz Back to the Future, scenes like Biff trying to force himself on Marty's mother would've taken a more overtly dark turn and any lightheartedness would have been immediately sucked out of the movie. When one considers how Back to the Future's ending is depressing, it also bleeds into how Stoltz's performance would've changed the sequels. Back to the Future II included a robbery, which with Michael J. Fox in the role feels like some light hijinks. With Eric Stoltz, the crime would've had much more weight. Finally, in Back to the Future III, 1885 Doc's death would not have been treated as a mere setback but have been more hard-hitting.

Marty returning to his life in 1985 as the same teenager he was before is a plot hole. The rest of his family changed in significant ways that affected their demeanors, life goals, personalities, and dynamics, all of which would have impacted Marty’s personality. He grew up as the most well-adjusted, popular member of his family, but Back to the Future’s alternate timeline suggests that changed. Stoltz’s assertion that Back to the Future's ending is depressing is essentially correct; Marty would be cursed with not knowing who he really is, which would be the equivalent of having retrograde amnesia. Even if Eric Stoltz's reading on Back to the Future is correct, it ended his time in the role.

What Eric Stoltz Did Instead Of Back To The Future

Despite losing out on Back to the Future, there are plenty of other Eric Stoltz movies. The actor had a very active career, especially in the 80s and 90s. Most recently, he appeared as Judge Meachem on The Good Fight. Instead of doing Back to the Future, he had three other movies come out in 1985. First was The New Kids where he played Mark, second was Mask when he took on the role of Rocky Dennis, and finally Code Name: Emerald where he appeared as Andy Wheeler. His next gig was Some Kind of Wonderful, where he played the part of Keith Nelson.

He got a big break with The Fly 2, and in that movie, he played the lead role of Martin Brundle. Finally, he was also in the 80s hit Say Anything as Vahlere. Despite not being Marty McFly in Back to the Future, Eric Stoltz movies like Mask and Say Anything are cult classics today, and he's managed to have a successful career.

Eric Stoltz Did Star In Back To The Future In The Flash Movie

The Flash from 2023 DC movie

In a moment of a joke from the past returning to the present day, The Flash movie had a Back to the Future gag in the movie. Fans of Back to the Future know there was a part in the movie franchise where Marty McFly went to the future and saw a promo for Jaws 19. There have also been movies like Last Action Hero that showed an alternate world where Sylvester Stallone was the star of Terminator. The Flash did this when it referenced changes Barry Allen made to the timeline as well. Not only did his changes ensure there was no Superman and have Michael Keaton return as Batman, but he also somehow erased Michael J. Fox from the Back to the Future franchise.

The scene happened when Barry Allen was talking to his past self. It was then that he learned that Fox never starred in Back to the Future and instead, Eric Stoltz was the star of the franchise. This means that not only was the world a darker place with no Superman, but it was also a darker place because Back to the Future remained a dark tragedy and not the beloved fan-favorite movie that it became over time.
