Rated R for strong graphic violence and pervasive strong language.No sex or nudity shown on screen, with the exception of a dessicated male corpse, which is shown unclothed very briefly.There are several scenes of sexual harassment of a female character, including some strong sexual language. The threat of sexual violence is implied but never occurs.
Day of the Dead features fewer incidents of violence per minute of screen time than Dawn of the Dead, but the scenes of gore are much more intense and convincing than those of its predecessor. Zombies are shown viciously devouring people; intestines are ripped out; limbs are ripped off; zombies are dissected "alive"; a man's arm is amputated by machete and cauterized (to save his life); people and zombies are shot, all in gruesome detail.
Day of the Dead contains marginally more profanity than any of the other films in the series, including numerous uses of sexual swear words ("fuck" and several of its derivatives), anatomical terms ("dick", "asshole", etc.), racial epithets ("jungle bunny"), and so forth.
Characters are seen smoking and drinking; a marijuana plant is briefly visible and a man is seen rolling a joint. A character is shown taking sleeping pills on several occasions.
The zombies are more terrifying than the sequels; they are stronger, more gruesome, more adaptable, and their attacks and "feasting" scenes are guaranteed to induce nightmares in children.
