Everybody get over it
This film is not child porn. Ooh, they smoke Marlboros. Ooh, they're doing jumping jacks in front of men. Ooh, they're talking about having sex. And having sex. Offscreen.
If the reason this isn't on dvd is because it's salacious then explain why the 1974 "Born Innocent" is.
Look at the films of the late 70's/early 80's. "10". Beach Girls. Spring Break. Malibu Beach. They were genre movies that actually were about sex(and actually showed nudity!) And they were fun. Little Darlings was one of the few that had a message. It's only in the past 10 or 15 years that sex has become forbidden in entertainment. Now an R rating means violence, which apparently is fine with the Moral Majority. But focus on sex and show nudity and the prudes come out of the woodwork. Have you seen Rambo? Children bayonetted. Arms and legs flying everywhere. People being decapitated and gutted. This is now acceptable entertainment.
So you take a cute film like Little Darlings and turn it into a call to arms for your morality soapbox. Do you realize that the message of the film is that the girl who had sex suffered, while the girl who didn't was happy and well adjusted?
Maybe it's the highly vocal prudes who are keeping this film from being released. That would be a shame. But the reality is it's probably song publishing rights.
Just get over it.
