Chan smacks Yang's bum

Some women with bikinis swimming in a pool.

There is some mild flirting/kissing/innuendo. PG-level.

Plenty of martial arts fighting. Characters get shot (moderate blood is sometimes shown) and blown up/incinerated. One villain has his head bashed in by a hard object (blood coats his head), while another is drowned.

Some language such as "h**l," "d**n," and "b**ch." Mostly PG-level, although depending on the version you watch one of the soundtrack songs may contain some uses of "f**k" (English-dubbed version only).

Some smoking and little drinking.

Some drug use. A woman is inject drugs in her hand.

References to heroin - the plot involves drug trafficking.

A guy throws protagonist's girlfriend down from helicopter in climax scene protagonist urges people to call ambulance this scene is complete intense.

The whole movie has a comedic feel, but a few villains are executed brutally.
