There's a lot of staged fight scenes with prop pistols, swords, and fake blood. At the beginning of the film, there's a large martial arts fight scene with swords.
A man walks into his friend's apartment and shoots him (some blood is seen). We find out that he's shot with a blank and they were just staging it.
The whole movie is centered around stunts, a man being repeatedly injured, and someone who has to fall down a large flight of stairs.
