Loosely based on the life of table tennis champion Marty Reisman, Josh Safdie's Marty Supreme is set over eight months of mayhem. It's 1952, and 23-year-old Marty is working in a shoe shop in New York. The film begins with a tryst in the stockroom and ends with the birth of a child. For Marty (Chalamet), his job as a salesman is beneath him.
