Broken Leg
Harrison Ford has been in some of the largest films in history, from Blade Runner, Star Wars, and Indiana Jones. The actor has been so iconic it is almost impossible for him to go anywhere and not be recognized. It would be harder to get away from the paparazzi as well when you have a broken ankle.
Harrison actually broke a bone on the set of Star Wars: The Force Awakens when a door fell down directly on his ankle. The director J.J. Abrams had to step in and help the crew lift the heavy prop door off of his ankle. They managed to resume filming after he was treated, he just had limited movement.
