In August 2017, Tom Cruise suffered an injury while filming a stunt of him jumping from one building to another. He was able to grab onto the other building thanks to a harness strapped onto him and his history of performing his own stunts for action films, but his ankle broke upon the impact of the jump. Cruise immediately got up and attempted to run it off, which is what the scene called for, before he and the crew decided to stop filming. Shooting was delayed for eight weeks following the injury, but the footage of the stunt used in the film's trailer just so happens to be the actual injury.
Alec Baldwin found his fight scene with Henry Cavill particularly challenging to execute because of Cavill's sheer size and musculature. Baldwin said about the encounter, "I had to do a fight scene with Henry Cavill and Henry Cavill as everyone knows plays Superman. Well, he really IS Superman. The guy's body is like it's made of marble. When you do fight scenes, you throw these punches, you tussle with the guy and you move him around. He's pretty hard to move around. And his shoulders are so big that when do they my close-up over his shoulder, I would say "Could you bend down please because your shoulders are in the way of my shot." He's just so BIG. But I had a ball working with him."
