Django: Unchained
When Leonardo DiCaprio slammed his hand on the table, he accidentally cut it on broken glass! However he carried on like nothing happened. “My hand started really pouring blood all over the table,” says DiCaprio. “Maybe they thought it was done with special effects. I wanted to keep going. It was more interesting to watch Quentin’s and Jamie’s reaction off-camera than to look at my hand. We did it bloodied and bandaged for the rest of the movie,” he said.
