It's True!

Leonardo DiCaprio cut his hand while the cameras were rolling on the set of “Django Unchained”, but kept moving through the scene, never breaking character. His real-life bloodied hand made it into the final version of the film. During one of the movie's most climactic scenes where DiCaprio slams his hand on a dining room table, he unintentionally slammed his hand into glass, creating a gash that later required medical care. But as his hand bled quite visibly, DiCaprio kept going, even using the hand as a new dramatic prop. At one point he smears his bloodied hand over Kerry Washington's face in an act of evil dominance; that was the take that director Quentin Tarantino kept in the film.
