Men seen in underwear.

Animal violence. Some animals are killed without any gore. A hog is also shown being killed and later being eaten.

There is a short scene in the beginning where ape-men kill another ape-man using bones.

A wild jaguar-like animal attacks (and presumably kills) an ape-man. Shortly thereafter, the ape-men learn to kill the hog-like animals (tapirs) near them, and there are scenes of them carrying the meat around and eating it.

No profanity, however religious people will be offended by uses of words like "damn" and "hell"

Some alcohol is consumed.

Most of the film contains mysterious, surreal, and potentially creepy atmosphere and imagery, and is often accompanied by a mysterious or even eerie score at times. The silence of space is also used to achieve similar effects.
