Apparently featuring Julia Roberts as his Lawyer.

Roberts would play a lawyer tasked with defending Darius McCollum, the criminal (and Internet celebrity) known for impersonating public transit authorities in order to drive away subway trains and Greyhound buses. McCollum, who is diagnosed with Asperger’s syndrome, has been arrested more than 25 times for such crimes. Roberts’ character would be his most recent lawyer, and his previous heists (starting at age 15) are shown throughout the film via flashbacks.
...I just hope it doesn't inspire copycats
