A male character is naked within the context of the plot (another character mentions his bare butt) is naked, but nothing is blatantly shown.

Comedic and highly unrealistic gore.

PG13 level profanity. B***s, A**, S***, D***, G******, Son of a B****, and rare appearances of F***.

Heavy drinking is implied at the begining.

The aliens are computer generated and very unrealistic looking. The scenes are done for comic effect rather than to produce horror or tension.
