Actress Julia Roberts will play a real-life attorney in Train Man, which tells the story of Darius McCollum, a New Yorker who became notorious for driving subways and trains illegally.

Based on a true story, Train Man will recount the life of McCollum, diagnosed with Asperger syndrome, who developed a life-long obsession with New York’s subways and trains, said The Hollywood Reporter.

Frequently arrested and imprisoned, he became a cult figure around the city after wanted posters warning passengers about him appeared throughout the city. Roberts will play McCollum’s long-time attorney Sally Butler.

Interestingly, Roberts won an Oscar for playing a tenacious law firm clerk in 2000’s Erin Brockovich.
