The song "Smell Yo Dick" is played inside a car as a comical effect

A reference to anal rape when discussing the film Deliverance.

Early on, the family sees a skinned, mangled animal carcass on the side of the road, ripped up enough that it's difficulty to determine what exact animal it was before it was killed. The size is somewhere between a rabbit and a medium-sized dog. The shot of the carcass is brief and the camera does not linger. This is the only blood or gore shown in the movie.

Character's bodies are twisted and folded when 'beamed' up into the spaceship, it is very brief and bloodless but brutal. For one character, we see her head fold backwards until it rests against her back, her arms fold backwards by the elbows, and finally her whole body folds in half backwards, each are accompanied with loud cracking sounds.

Some gun shots, all but one of them offscreen. We do not see any bullets hit a person or an alien, just a door/wall.

Few uses of shit.

Religious Profanity: The Name of Jesus taken in vain a few times, as exclamation. "Oh my God" and "God" used in various scenes during the movie.
