A man reads a sexual book then jokes about it briefly (It all lasts about 15-20 seconds).

Near the end of the film a group of people try to escape from their captors by playing a few practical jokes (see Alcohol/Drugs/Smoking for more) to turn the two tribes (eating together) against each other, then a fight breaks out between the tribes.

Also before the above the group gets kidnapped and fighting breaks out.

None.

Near the end of the film one of the practical jokes played is exploding cigarettes.

Throughout the film people smoke.

A few times people do drink alcohol.

Near the end two men are about to take a poison pill each

Children might find the fight scenes scary.
