Filmmaker Todd Solondz himself had originally wanted someone who really had cerebral palsy to play the role of "Marcus" in his "Storytelling" film, but Fitzpatrick convinced Solondz him in the role. Fitzpatrick himself researched by working with people with cerebral palsy as well as spending time in C.P. clinics as he wanted so much to be cast in a Todd Solondz film.
When director Larry Clarke first discovered Fitzpatrick himself at Washington Park was trying to perform certain skateboarding tricks, and every time he was unsuccessful, he would scream and curse. Clarke instantly saw something there he wanted for his "Kids" movie.
Leo was cast in the Robert Redford movie The Last Castle in 2001, but he was hit by a drunk driver after leaving a friend's party two days before the shooting.
During the crash his leg suffered severe nerve and muscle damage. He was unable to walk for a month and had to go through physical therapy, which caused that he was dropped from the movie.
His height is 6' 1" (1.85 m).
Leo reunited with Larry Clark in the 2001 movie Bully. He played Derek Kaufman.
Most people will recognize Leo Fitzpatrick as one of the rambunctious teens featured in Larry Clark's 1995 film, "Kids."
Leo: (on Kids) I think that was part of the distributor's scheme. Miramax didn't introduce the actors at any of the screenings. That's why a lot of people thought Kids was a documentary. I still meet people who think it was real. After I made Kids, I went back to working at a skate shop, just living life as a stupid skateboarder. But people would call the store and say, "I know you're that guy from Kids. I'm going to come down there and kick your ass." I would say, "Calm down, it was only a movie."
Leo: (on getting the part in Kids) I've known Larry Clark since I was fourteen. I've always skateboarded in Manhattan. Larry got into the scene in the early 90's, taking pictures and skating with us. Then one day he was like, "I just got the money for this movie I've been talking about for the past two years. Do you want to come in and audition?" I said, "Sure." I had nothing better to do.
Leo: (on Storytelling) Before this, I never cared about a movie enough to really try very hard to get it. I usually go through the audition process just to please my agents, and I've blown a ton of auditions on purpose just because the movies were shit. But "Storytelling" was completely different because I'm a huge Todd Solondz fan.
