Leonardo DiCaprio – Django Unchained
During one of his character’s many emotional outbursts, Leonardo DiCaprio accidentally crushed a glass with his hand during a scene. Producer Stacey Sher recalls, “Leo had slammed his hand on the table countless times and he moved his hand further and he crushed a crystal cordial glass. Blood was dripping down his hand. He never broke character. He kept going. He was in such a zone. It was very intense. He required stitches.” You can see DiCaprio casually picking some glass out of his palm during the intense scene.
