Man in underwear with blatant tiger prints comes out to the door.

One kiss scene.

Final fight Jackie Chan and Tony Leung.

The film may seem surprisingly light, PG-13 level, only until halfway through the film it becomes R-rated level strong violent and bloody with strong crunching and stabbing sound effects. The overall tone reminds PG-13 mostly, but the violence gets stronger.

As the film progresses, the violence gets bloodier and more brutal, as many characters either get into brutal fist fights or stabbed.
