And that scene isn't child-porn because..

The previous poster is correct about the difference between laws then and now.

There wasn't a child pornography law then.

When child pornography laws finally did come along some years later, they applied at first only to the production and selling/distribution of it. The possession of it wasn't illegal all the way until years after that!

People don't realize that there are lots of things that were legally available in the 1970s that are actually likely illegal today. The child porn laws are more strict than ever nowadays.

The law states that the sexual performance of a child under 18, rather real or simulated, constitutes child pornography. It goes on to say that even certain lewd posing, or instances where there is a specific focus on the genital areas, is child porn, also. It even now says that if it is implied that sexual conduct has, is, or will take place between children or adults and children, that this may also be child pornography. Under these broad terms, many things made in the 70s would be never be made today, and would likely be considered child pornography today. And yet another distinction of note is that the law further states that in a case of alleged child pornography, unlike other obscenity charges (wherein the work as a whole must be looked at), the law states that the whole work need not be considered. If there is one frame of Child porn in a film, the work is illegal, unless the child porn element is removed. It doesn't matter what the work as a whole is about.

To correct another poster, they stated that Brooke Shields did not appear nude. That is incorrect. She appears completely nude, at the age of 12, in the 1978 film, "Pretty Baby". It is also implied that she has been sexually active with several grown men, as well. Now, Jodie Foster, in the film, "The Little Girl Who Lives Down the Lane", had a body double (actually her only slightly older sister) for a brief nude scene. It is also implied in that film that Foster has been sexually active with an older boy several times, and she is stalked by creepy pedo neighbor Martin Sheen. She also plays the chil hooker in "Taxi Driver", as well. And there are certain European films that are likely not legal at all today, like some of the David Hamilton films, and especially the notorious "Maladolescenza". In 1978, "Maladolescenza" was released by New World Pictures in the US briefly. It played in NYC art houses without incident. Today, no one in the whole world will release it. One Austrian company tried in 2004, and resulted in its getting officially banned and pulled from shelves in Austria. No one else has tried it since. And a fellow got arrested in THE NETHERLANDS for possessing a copy of it. You know people are taking it seriously when The Netherlands arrests you for it!
