What movie is this?! Best answer given! please!!!!!!!?

Okay, what's the movie where a guy cuts off a girls ears and sends the ears in a box to another girl. and then another part in the movie, a girl sucking on a lollipop asked to put on the guys coat she was with and it was a black coat and she reached in his pocket and there was teeth in it.
