A woman is naked and falls from a tub onto a man but only her backside is seen, two characters wake up naked in the woods no frontal nudity.

A male is shirtless often for the latter portion of the film with his pants hanging fairly low, this could offend some viewers.

There are some very brief nudity basically male and female rears and one scene with a glimpse of a woman's breast.

Quite a bit of blood, gunshot wounds seen, alien drilling into someone's head, removed human heart beating by itself, woman's back is open with tunes sticking out of it

Dead animals are shown. People are abducted by aliens. People are shoot by mistake and on purpose; blood splatters An alien is kill and dismembered People are shown with parts of their body removed. A head is being perforated by an alien device

The f word is used about 5 times, as is p***y and one religious profanity.

Aliens arrive, abduct people and do experiments. People are trying to be kill by the army and police
