Gangs of New York - Blood Smears on Leonardo's Face
This occurs in the scene at the end of the movie when Daniel Day Lewis's character dies on the pier and Leonardo Dicaprio's character is present. The camera shows Leonardo as he's talking and he has blood and dirt smeared on his face from the explosion of the cannon ball. Then the camera moves to Lewis for a moment. When the camera goes back to Dicaprio the blood and dirt smears on his face look completely different, and there's no suggestion that he wiped his face.
