Some sexual references.

A man and woman are shown kissing.

Throughout the movie, people are "grabbed" by the aliens. Lots of screams can be heard.

An alien jumps on a man's face. He breaks the light while thrashing, so nothing is seen, but the struggle can be heard.

A head falls down from the roof and hits a man.

An alien attacks a man, drawing blood. The alien then throws up blood. The humans then stomp on the alien to kill it.

A few more instances of aliens attacking humans and humans attacking aliens. Some blood, some heads.

About 7 uses of the f word. (Deleted. Personal opinions about ratings are not appropriate for the Parents Guide.)

Some religious swearing. Some strong language, including the "S" word and "F" word and "C" word. "Bastard" is used a few times.

Some smoking. Lots of drinking at a bar. Lots of people are drunk.

See violence & gore section. Scenes of alien attacks would be very intense and frightening for young children.
