Obviously, this movie is a blatant rip-off "The Blue Lagoon". Nevertheless, that movie was so bad that even a cheap-jack Italian product like this could have easily improved on it--but no such luck. The original "Blue Lagoon", despite its cinematic pretensions (and PG rating), was little more than an excuse for perverts of all ages to leer at a pubescent Brooke Shields (and/or her pretty-boy co-star, Christopher Atkins), even though the former reportedly used a body double for all her nude scenes. This movie casts a 19-year-old Sabrina Siani, and is thus a little more straight-forward in its sexploitation angle. Unfortunately though, aside from a lot of breast-and-thong nudity and a couple tame sex scenes, this Italian time-waster otherwise apes the boring American movie with a laughably idyllic and sickeningly romantic coming-of-age-on-a-desert-island tale (the fact that these characters are a little long in the tooth to be just discovering the joys of sex is explained by making them Olympic athletes sequestered away in training before being marooned by a plane crash). I was hoping for maybe a sexy version of "Lord of the Flies", but this annoying pair is so nice that they can't even cook up a cute bunny to eat even though they're (presumedly) starving.
There's also a really dumb sub-plot involving a big hairy guy who is also on the island (for reasons never explained by the English soundtrack). He starts out as villain, then becomes a friend, then a villain again, and then he mercifully seems to drown, but then . . . no it's just too stupid. . .
The only, and I do mean only, thing this movie has going for it is Siani's incredible nude body, but it was used to better effect later in Fulci's "Conquest" (where her character wears a mask the whole time which partly conceals her godawful acting). Earlier, I guess, she had also been one of Jesus Franco's underage jungle girls in one his lesser cannibal movies. She is pretty impressive physically, but not even remotely worth enduring THIS movie for.
