Professional wire work remains a staple in action filmmaking. Actors often perform dangerous stunts, but industry safety standards are constantly evolving to protect them behind the scenes.
This quiz covers the technical side of stunts, including common injuries, communication protocols on diverse film sets, and the mechanics of rigging. Some questions focus on equipment, while others highlight the real risks performers face on set.
