He was almost killed twice during the filming of The Good, the Bad and the Ugly. He was almost poisoned on the set after drinking acid used to burn the bags filled with gold coin to make them rip open easier when struck with the spade. The acid was housed in a lemon soda bottle. He drank milk and filmed the scene with a mouth full of sores. He would have been decapitated during the train scene if he lifted his head up. You can see the step that would have knocked off his head in the wide-shot.
