The following firearms were used in the film Billy Bathgate:
Several of Schultz's men, including "Lulu" Rosencrantz (John Costelloe) and Mickey (Billy Jaye) carry M1911A1s. Dutch Schultz (Dustin Hoffman) uses one when he shoots Julie Martin (Mike Starr) in the head (but this later changes to a M1903 Hammerless). Several of Luciano's men, including Charles Workman, have them during the final shootout as well.
