Rare footage of Eric Stoltz as Marty McFly has resurfaced online, offering a glimpse of the alternate “Back to the Future” that almost reached theaters.
Stoltz, then an up-and-coming dramatic actor, had already worked opposite Claudia Wells as Jennifer Parker for roughly six weeks when director Robert Zemeckis made the painful decision to fire him. The footage shows Stoltz in character during scenes that would later be reshot entirely with Michael J. Fox, who was 24 when the finished film debuted ahead of the July 4th holiday in 1985.
The casting shakeup was not the film’s first choice gone awry. Fox had been the team’s initial pick for Marty, but his commitment to the hit sitcom “Family Ties” initially removed him from consideration. Studio president Sidney Sheinberg strongly encouraged Zemeckis to cast Stoltz instead, pointing to the actor’s powerful performance in “Mask” as proof he could carry a major picture. Zemeckis and the producers went along with the studio’s preference.
Stoltz approached the role with method-actor intensity that quickly became legendary on set. He answered only to the character’s name and wore Marty’s clothes to and from set each day. The cast and crew admired his dedication, but his seriousness created friction. Thomas F. Wilson, who played bully Biff Tannen across the trilogy, was among those rubbed the wrong way by Stoltz’s demeanor.
The deeper problem was tonal. Though “Back to the Future” is shelved as science fiction, its engine runs on comedy, particularly from Marty’s rapid-fire interactions with Doc Brown, his parents, and Biff. Stoltz was undeniably skilled, but he could not hit the comedic pitch the role demanded.
In early January 1985, with the production already falling a month behind schedule, the team approached Fox about taking over. A few days later, Zemeckis delivered the news to a heartbroken Stoltz. Fox stepped in despite “Family Ties” remaining his priority, and his arrival got the troubled production back on track.
At that point in his career, Fox had only two other film credits: “Midnight Madness” and “Class of 1984.” His television fame made him arguably the most recognizable face in the cast, second perhaps only to Christopher Lloyd, the “Taxi” and “One Flew Over the Cuckoo’s Nest” veteran who played Doc Brown.
The recasting dominoes kept falling. Wells had appeared opposite Stoltz and then reshot her scenes with Fox for the first film, but scheduling conflicts kept her from returning for the sequels. Melora Hardin of later “The Office” fame was briefly brought in as Jennifer for “Back to the Future II,” only to be dismissed for being “too tall” opposite Fox. The production wanted Wells back, but she turned down the offer to care for a sick family member. Elisabeth Shue ultimately assumed the role for both sequels.
Getting “Back to the Future” made at all had required extraordinary persistence. Zemeckis collected more than three dozen rejections before Universal finally greenlit the time-travel concept. Sheinberg’s hands-on involvement continued through development and into the casting decisions that shaped what audiences finally saw.
The finished film became a defining summer blockbuster for Universal, spawning two sequels filmed with unusual overlap—production on the third installment had already begun before “Back to the Future II” even reached theaters in 1989.
The resurfaced Stoltz footage joins a small but growing archive of what-might-have-been Hollywood moments, preserving the performance of an actor who came close to anchoring one of the most beloved franchises in film history.
