16. Michael J. Fox
It’s shocking to hear we almost lost Marty McFly during the hanging scene from Back to the Future Part III. Fox had rehearsed the perfect way to protect his throat, but something terrible happened. Fortunately, the crew realized he was in danger before things got out of hand.
17. Jaimie Alexander
If you’re going to be cast in a Thor movie, you better be ready for some cuts and bruises. Jaimie Alexander learned this lesson the hard way. While filming Thor: The Dark World, the young, multi-talented actress suffered a plethora of injuries. She told reporters, “I herniated a disk in my thoracic spine, dislocated my left shoulder, tore my right rhomboid, and chipped 11 vertebrae.”
18. Jackie Chan
Jackie Chan has been flying, punching, and kicking his way around movie sets for decades now, and we have loved every minute of it. He once hurt his noggin so bad on the set of Armour of God II that he needed brain surgery. But that didn’t stop Jackie. He’s the bravest of them all.
19. Nicole Kidman
Even a calm day on set can sometimes result in a painful injury. Such was the case on Moulin Rouge when Nicole Kidman twice fractured her ribs. Once, while she was performing a dance routine and the other whilst trying to squeeze into a corset.
20. George Clooney
Many of Clooney’s fans don’t even know that the famous actor almost died as a result of a head injury suffered on the set of his 2005 film, Syriana.The pain lingered with Clooney for weeks. It wasn’t until meeting with a neurologist that the E.R. alum learned that he was leaking spinal fluid.
