We all have that image in our heads. A kid in a red puffer vest, frantically checking a watch while a DeLorean screams toward 88 miles per hour. For most of the world, Michael J. Fox acting is synonymous with Marty McFly. He was the twitchy, charismatic heartbeat of the 1980s. But if you look closer at the footage from his later years, or even his peak on Spin City, you’ll see something else. You’ll see a man performing two roles at once: the character in the script, and the guy trying to keep his own body from betraying him on camera.
Honestly, it’s a miracle he stayed in the game as long as he did. Most actors would have packed it in the second their hand started to shake during a close-up. Fox didn't. He spent nearly thirty years hiding a degenerative disease in plain sight, using desks, pockets, and props to mask tremors that would have sidelined anyone else. It wasn't just about "the show must go on." It was about a guy who genuinely loved the craft so much he was willing to fight his own nervous system for one more take.
The Secret Technique of Hiding in Plain Sight
When Fox was diagnosed with Parkinson’s in 1991, he was only 29. He was at the top of the world. He had just finished the Back to the Future trilogy and was transitionining into more "grown-up" roles like Doc Hollywood. Suddenly, he was told his career had an expiration date.
Instead of quitting, he entered a period of deep denial—and incredible ingenuity. If you watch the later seasons of Spin City, you’ll notice Mike Flaherty leans on things. A lot. He’ll stand behind a couch, grip the back of a chair, or keep one hand shoved deep into a trouser pocket. These weren't just "cool guy" poses. They were physical anchors. He was literally holding himself down so the camera wouldn't catch the vibration.
Why the "Hiding" Phase Mattered
It’s easy to look back and say he should have been open sooner. But at the time, Fox was terrified. He thought if people knew, they wouldn't find him funny anymore. He told The New York Times Magazine that he was worried the audience would only see the disease, not the character. So, he developed a style of Michael J. Fox acting that was hyper-kinetic to mask the involuntary movements. If he was always moving—pacing, gesturing, fidgeting with a pen—the tremors just looked like "Alex P. Keaton energy."

Breaking the Mask: The Good Wife and Beyond
Eventually, the mask had to come off. By the time he appeared as Louis Canning in The Good Wife, Fox had stopped trying to hide the Parkinson's. In fact, he used it. Canning was a cynical, brilliant lawyer who weaponized his disability to win over juries and frustrate opponents. It was a masterclass in adaptation.
He wasn't Marty McFly anymore. He was something grittier.
Working on The Good Fight and Designated Survivor brought a new set of challenges, though. It wasn't just the physical movement; it was the memory. In a 2022 interview on Mike Birbiglia’s Working It Out podcast, Fox got real about the "blank." He described standing on set, knowing he had seventy pages of dialogue in his head just years prior, and suddenly being unable to remember five lines.
"I couldn't remember the lines. I just had this blank," he admitted.

Why He Finally Retired in 2020
The decision to officially retire wasn't a sudden whim. It was a build-up of several "perfect storm" health issues. In 2018, he had a terrifying scare with a benign tumor on his spine. He had to learn to walk all over again. Then, he had a bad fall in his kitchen and shattered his arm.
When he wrote his memoir No Time Like the Future, he was incredibly blunt. He said there is a time for everything, and his time of putting in 12-hour workdays and memorizing seven pages of dialogue was "best behind" him. He didn't want to do it halfway. If he couldn't deliver the performance the audience deserved, he'd rather not do it at all.
The Surprising Return: Shrinking Season 3
Just when we thought he was done for good, 2026 brings a bit of a curveball. Fox recently popped up in a guest role for the Apple TV+ series Shrinking. It makes sense—the show’s co-creator, Brett Goldstein, and star Harrison Ford (who plays a therapist with Parkinson’s) have spoken about how much Fox inspired the series.

In a meta-twist, Fox plays a character who also has the disease. He told AARP that it was the first time in years he didn't have to worry about "acting" healthy. He could just show up, tremors and all, and be in the moment. It’s a full-circle moment for a guy who spent decades doing the exact opposite.
What You Can Learn From His Journey
Fox’s career isn't just a Hollywood story; it’s a blueprint for resilience. If you're looking for the "takeaway" from his decades in front of the camera, here’s the reality of what he taught us:
- Adaptation is better than perfection. He didn't wait for a "cure" to keep working. He changed his style to fit his reality.
- Know your limits. Retirement wasn't a failure; it was an act of self-respect. He recognized when the "cost" of acting was higher than the reward.
- Humor is a shield. Even in his darkest memoirs, he uses wit to bridge the gap between him and the reader. It’s how he stays "Michael J. Fox" instead of "The Guy with Parkinson's."
If you want to see the best examples of his range, skip Back to the Future for a night. Watch Casualties of War (1989) to see him hold his own against a terrifying Sean Penn, or catch his guest arc on Rescue Me, which won him an Emmy. You'll see an actor who was always more than just a kid in a DeLorean.
