Guns have dominated American movies for decades, with millions of fake rounds of ammunition fired off by John Wayne, Sly Stallone, Keanu Reeves, Linda Hamilton and many other action stars. But this penchant for onscreen violence has ended in real life tragedy several times throughout Hollywood history—and did so once again on Thursday, when the cinematographer Halyna Hutchins was killed after the actor Alec Baldwin discharged a prop firearm during while filming the movie Rust in New Mexico. The incident—which also seriously injured the film’s director Joel Souza—has led to renewed calls by many in the film industry to ban real guns on movie sets.
