From a brutal film comes a crazy scene. What do you do with a corridor full of people and a claw hammer? Well, this I supppose!
Apparently Min-sik Choi did all his own stunts for this film, and it kinda shows in this scene. But that's one of the charms of this scene, it's not slick and stylised, it really looks as though it's a normal guy battering people with a hammer!
