Justin got his SAG card while working on the film Don Juan DeMarco with Johnny Depp, Faye Dunaway, and Marlon Brando. During a break in filming he was sitting in a stairwell when Marlon Brando and an Assistant Director walked in and began a heated discussion on whether Marlon would be working later that day than scheduled. When the Assistant Director saw Justin was in there with them he told him to leave but Marlon Brando said "The Kid stays".
