The baddest smack down scene I ever saw in a movie is at the beginning of a movie with an innocent sounding title called, Pan's Labyrinth.
Early in the movie you see a German? soldier make a man kneel down and keeps hitting him on the bridge of his nose with the butt of a beer bottle until the man's face completely caves in. Very graphic!


If you haven't seen it yet it is a fairytale movie for adults, no nudity but plenty of gore and scary monsters so keep in mind it really isn't for little kids to watch.
