Souza, 48, was taken to hospital after being hit in the shoulder by the bullet and was later discharged.
Script supervisor Mamie Mitchell is also taking legal action against Baldwin, assistant director Dave Halls and the movie’s producers, claiming that the scene in Rust did not call for a gun to be fired.
Her lawyer, Gloria Allred, said “industry veteran” Baldwin should not have trusted a gun handed to him by anyone other than the prop master or armourer.
The weapon was given to him by Halls, who allegedly shouted “cold gun,” meaning not loaded with live rounds. No criminal charges have been filed.
