Very brief, comedic sex scene where the woman is scene on a bra

A man at a shop on the road keeps asking Charlie if he wants to have sex, he refers to oral and other positions.

There are scenes throughout the whole movie where strange green aliens eat and rip apart humans. The blood and gore, while limited, are done in a bit of a tongue and cheek way; not totally fake, but also not fully realistic.

A man is killed with a spear.

Throughout the whole movie curses are used. 20-30 F*, numerous sh* and other curses are used.
