Viggo Mortensen breaks his toe in LOTR
In this scene Aragorn believes Merry and Pippin to be dead. In a moment of great anger and hopelessness he kicks a helmet and falls to his knees in despair. Very intense. If you notice, the scream is very convincing and sounds like physical pain, because it is. Peter Jackson wanted Viggo to kick the helmet close to the camera, as it would make for a great shot. After 4 takes of getting the helmet closer and closer, Jackson asked for one more take. In this Viggo kicks the helmet, breaking 2 of his toes in the process. Despite this, he uses this pain and continues to play out the scene, not alerting anyone until later that he had broken his toes.
