How Tall is Michael J. Fox?

Michael J. Fox has never been a terribly tall person, which is why he was probably able to nail the whole High Schooler look when he starred in Back to the Future in his late 20s and early 30s.
He is 5 feet, 4” tall. For metric users, this is around 1.63m. Although, interestingly, his illness may have something to do with the shorter height.
If you know Michael J. Fox, then you will know that he has now retired from acting. This is because, at the mid-stage of his career, he was diagnosed with Parkinson’s Disease. Studies have shown that those who have Parkinson’s Disease (particularly males) tend to be much, much shorter than the average.
Interestingly, Michael’s short height was a problem during the early part of his career. He almost didn’t get cast in Family Ties (which meant no Back to the Future), because casting directors believed him to be too short.

A lot of people believe Michael J. Fox to be far younger than he is. This is because he was meant to be playing somebody around 16 years old when the Back to the Future movie series came out in 1985 (and ran on through to 1991). But, the truth is, by the time the first movie came out he was 25, and with the third and final movie, he was in his 30s. So, certainly on the older side of things! No offense to anybody in their 30s, of course.

Did you know that Michael J. Fox almost didn’t play Marty McFly in the Back to the Future series? The casting director wanted him, but he had a lengthy contract on Family Ties. As a result, the first half of the movie was filmed with Eric Stoltz in the lead role. However, shortly after, he was released from the Family Ties contract. The movie was reshot with Michael J. Fox in the lead role. By all accounts, Eric Stoltz doesn’t really hold a grudge about it either.

However, Michael was still a keen guitarist. He wanted to do something for the scene. So, all of the hand movements he makes on the guitar match up with the sounds that you hear in the movie. It helps to give that scene a little bit of extra ‘realism’.
