There is no sex or nudity in this film.

Many people are killed by the tidal wave.

A man is hit by a cage in the start of the movie. He bleeds, and later sinks with the ship.

A man punches another man. Very brief and is in a comic manner.

People are squashed, thrown away by objects after the first tidal wave. An object lands right in front of a man who barely survives.

More physical violence in the Uncut/Korean version, including punching, kicking, etc.

F**k and motherf**ker appear on the English subtitles.

Adults smoke and drink throughout the film.

A scene where people are electrocuted in the water may be upsetting to some viewers.

The part where people are killed by objects may be unsettling for younger viewers.
