Michael J. Fox Reveals Grueling 20-Hour Filming Days

Michael J. Fox, at age 63, has shared the intense challenges he faced during the early stages of his career while managing simultaneous roles in “Back to the Future” and “Family Ties.” In his memoir, Future Boy, Fox recounts the exhausting schedule and physical toll he endured during the winter and spring of 1985, which highlighted his remarkable endurance amid difficult circumstances. His experience captures the struggle of balancing two major productions, showcasing the reality of Michael J Fox filming struggles.

Balancing Dual Lead Roles in Two Hit Productions

During 1985, Fox was simultaneously portraying Marty McFly in the iconic film series “Back to the Future” and playing Alex P. Keaton on the popular television show “Family Ties.” This double responsibility required him to switch between these very different characters daily, leaving nearly no room for rest. At just 23 years old, Fox described living “two too many lives” in one body as he managed the relentless work.

A typical day began early with rehearsals for “Family Ties” starting at 7 a.m., followed by a full day of filming that went straight into evening hours. Immediately after, he would be transported to Universal Studios to continue shooting “Back to the Future” late into the night, often concluding at 3 a.m. His rest was limited to just a few hours before starting the cycle over again. As Fox wrote,

“I was Alex during the day, Marty at night, and Mike disappeared somewhere in between,”

emphasizing how his personal identity was nearly lost amid the constant shift between these roles.

Enduring Exhaustion Amidst Demanding Filming Hours

The exhaustion was so severe that by the end of a night shoot, Fox would be completely drained. He recalled,

“By 3:00 a.m., I’m passed out in the backseat of the station wagon,”

describing how his driver took him home to sleep briefly before facing another long day. Despite such extreme fatigue, Fox never allowed his commitment to falter and pushed forward through the difficult months.

Those around him, including his “Family Ties” co-star Justine Bateman, were often unsure how he managed the intense schedule without showing it openly. Bateman admitted she couldn’t tell when he ever rested, telling Fox,

“If anybody could do it, it was Mike,”

which highlighted the drive and sheer determination that fueled his work ethic.

Behind the Camera: The Risks Faced During Filming

While Fox’s physical endurance was tested on set, the dangers of filming added another layer of tension. Assistant director David McGiffert recalled intervening on a risky stunt proposed by director Bob Zemeckis, involving a car pushing Fox on a skateboard. McGiffert warned it was a heartbeat away from disaster, resulting in the decision to use a stunt double for safety.

Despite precautions, Fox encountered a near accident during the filming of “Back to the Future III,” when he miscalculated a stunt involving a noose. This caused him to momentarily lose consciousness before the crew was able to assist, underscoring the real physical hazards Fox faced to bring his characters to life on screen.
