PARENTS who plan to take kids to Leonardo DiCaprio’s “The Beach” this weekend may want to consider the drugs, profanity, nudity and violence that earned the film an R rating.

The film takes place in a commune of pot smokers in Thailand, and contains several uses of the F-word.

There is a brief flash of leading lady Virginie Ledoyen’s naked breasts when she and Leonardo DiCaprio meet for a moonlight tryst.

Later, DiCaprio and Tilda Swinton are fleetingly seen making love in profile behind gauze curtains.

The movie’s violence is more direct.

Four young American teenagers are mowed down by machine-gun fire, and the camera lingers on the bloody results of a shark attack.

Early on, a character who commits suicide is shown with a slit throat.–
