Male nudity is shown. Bare butts.

Dira Paes who is the main female tribe character has breasts and butt visible throughout the film.

There is a lot of female nudity. (95% of nudity is tribal)

Cannibalism, people being impaled on wooden spears, natives being shot with both guns and arrows. While the the cannibalism is never shown, the other scenes are very graphic.

Absolutely none.

The natives use drugs in their rituals.

Some drinking in seedy bars.

Some suspenseful action sequences and the Fierce People are quite menacing.
