Common Sense Note
Parents need to know that the main questionable content in The Blue Lagoon is nudity, and there's a lot of it. Both male and female bodies are seen, fully frontal once or twice, and quite a few times Richard's penis and Emmeline's breasts are clearly visible. An argument can be made, and at the time the movie was released it certainly was, that filming and showing children in the nude (at all stages of development) is inherently wrong, and those who feel that way should steer clear. If nudity is not an issue, the movie is otherwise fairly tame. There are a few extensive scenes of caressing and some kissing as the protagonists are observed following nature's course without any kind of guidance and almost entirely ignorant about human development. There are a few startling images of blood, a moderate spanking, and a human-sacrifice ritual that doesn't show the actual killing but does show a spurt of blood.
Most of the sexual content is from the nudity of children at all stages of development: infant, toddler, pre-pubescence, and post-pubescence. Both Richard and Emmeline are seen a few times fully from the front, and they're frequently seen swimming naked with Richard's penis clearly visible. A baby boy also swims naked, and his genitalia are fully seen. Emmeline's bare breasts are seen several times, but usually she's scantily clad. The children are shown going through the stages of puberty, noticing their changing feelings and emotions and growing physical attraction to each other. They don't act on those feelings until they're a bit older, but once they discover sex they're shown kissing a few times, and there are several extensive scenes of caressing, mostly innocuously on arms, backs, and the shoulder area, but Emmeline's breast is shown being caressed a couple of times. Actual sex is only hinted at as characters, for example, roll off-camera and are next seen asleep and entwined. More advanced sexual behavior is also hinted at once when Emmeline is nursing their baby, and it's implied that Richard suckles the other breast. We see Emmeline get her first period, have morning sickness, feel the baby move, give birth, and breastfeed. Richard is seen from behind masturbating, and Emmeline later mentions that she's seen everything he does.
Young Richard and Emmeline are briefly shown getting spanked, although not terribly harshly. They struggle against it (Emmeline bites the spanker) but aren't shown as seriously hurt. A fire breaks out on the ship, and passengers and crew struggle with each other while attempting to escape. Richard slaps Emmeline in the face after she hits him on the head with a coconut. A human skull, a dead body, and a full skeleton are shown. There are several brief glimpses of blood and gore: The apparent remnants of a ritual are briefly seen as an indistinct but small, bloody mass; Richard witnesses a human sacrifice, and although the killing's not shown directly, blood is shown spurting onto the executioner's face; stones flow with blood; a lot of blood is briefly shown in water and some is on Emmeline's hands when she gets her first period; bloody hands are briefly shown from rope burn. Richard and Emmeline attempt suicide together by eating poison berries.
This movie is meant to entertain and titillate and doesn't try to offer positive or negative messages.
