Read the IMDB pages on that one: actually, while The Little Girl Who Lives Down The Lane is indeed about a 13-year-old character played by a 13-year-old Jodie Foster (which disqualifies it from the list in any case, since that was specifically stated to be about 12-and-under characters), the sex scene with her similarly underage boyfriend was actually her 20-year-old sister Connie Foster in a wig. Granted, the trivia page indicates Jodie was pretty upset about that scene being included in the movie anyway, and denounced one of the producers as a pervert who wanted her to show some skin...

As for Gigi, again: "We're not talking about trashy movies in which teens played by twenty-somethings or even by actual teens get all wildly promiscuous on-screen, we're talking about tweens and kids in the single digits doing the four-legged frolic." So again, presumably left off the list because it was disqualified.

Given that the thread was about movies that featured kiddie sex (and I think 13 year olds are still kids even if you don’t), the fact that a body double stood in for Jodie Foster does not disqualify the movie as having portrayed kiddie sex. As to “Gigi,” the premise is morally repugnant.
