Michael J. Fox’s son, Sam Fox, is an exact copy of his father in his young years

Of the actor's four children, his son not only looks like him, but also plans to follow in his footsteps.

Michael J Fox is best known for his role as Marty McFly in the Back To The Future films. But those films are already over 30 years old, and since then Michael has had 4 children with his wife, Tracy Pollan.

As reported by Fabiosa, Michael has always been a self-proclaimed "incurable optimist," despite every reason he has not to be.

At just 29 years old, he was diagnosed with Parkinson's disease. Even then, he chose to look on the bright side of life, and started up the Michael J Fox Foundation to support researchers of the disease in the hopes of finding a cure.

Fortunately, he has always had a very supportive partner in Pollan, who has stuck by him through the years.

The couple's oldest child, Sam Michael Fox, was born in 1989, just 2 years before Michael's diagnosis. Sam not only inherited his father's dashing good looks, but apparently also his sunny outlook on life!

The father and son duo share the same smile, hair, and facial structure, and certainly the same eyes as well. The pair often spend time together, and Sam is even planning on starting a career as an actor just like his father.

Aside from Sam, Michael and Pollan also had three younger daughters.

Twins Aquinnah Kathleen Fox and Schuyler Frances Fox just recently celebrated their 23rd birthdays in February, while the baby of the family, Esmé Annabelle Fox, is just 16 years old.
