Milla nude?

Yes she was under 18 in this movie. It's not child pornography to show someone under 18 nude as long as it's done in a way that doesn't constitute "lewd or lascivious exhibition of the genitals or pubic area." If you see an adult age actress nude in a movie do you consider it to be pornography?

Actually "child porn" laws only apply to full genitalia being shown in a sexual context. For the most part, as long as the genitalia isn't shown in a sexual context, then its fine. Nudist videos can legally be sold in both Canada and the USA that show full nudity of minors, including the entire genitalia. The Supreme Courts in both the USA and Canada have ruled that simple nudity does NOT constitute pornography.

Furthermore, even sexualized nudity or sexual content involving minors IS LEGAL, provided that the work has bonafide "artistic merit or a medical, scientific, or educational purpose". This ruling was handed down by the Supreme Court in the USA. ALL "child porn" charges must be thrown out if the work, as a whole, has any of these merits.Since Return to the Blue Lagoon has legetimate artistic merit, any charges of "child porn" would be thrown out or quashed by any higher court. They could have had the girl completely nude and crawling around on the beach, with her butt and pussy pointed at the camera, and no "child porn" charges would have held up, since the work as a whole has bonafide artistic merit. In fact, the controversy would have generated millions in free publicity.

At Play in The Fields of the Lord shows a young boy completely nude with his penis fully visible for an extended time. No charges of "child porn" were even filed, since they would never hold up and the studio has lots of money to hire good legal help. The film 1900 by Bertolucci showed a boy completely naked and touching his ERECT penis. It was released by a major studio and shown in theaters. The movie Pretty Baby shows a 12 year old Brooke Shields fully naked several times.Virtually every Pasolini film contains full nudity of both male and female teenagers, often in sexualized situations. These films are widely available and "child porn" charges have never been filed, since they would not stand up in court.

The Tin Drum shows a boy actually engaging in sexual activity with an older, teenage girl. Child porn charges were filed by the police but later quashed in court because, even though there is real sexual content involving a minor, the work "as a whole" was deemed to have legitimate artistic merit. The police department was ridiculed for laying these charges.

In short, full nudity of minors can be portrayed, even in a sexualized way, as long as the film has legitimate artistic merit, and is not just pornography where the dominant purpose is to sexualy arouse/titillate the audience.
