In 1978, Louis Malle (the guy who liked to make movies about incest, too) directed Pretty Baby starring a then 13-year-old Brooke Shields--who played the pre -pubescent daughter of a prostitute, and who is 'bought' by an adult man.. (played by Keith Carradine, I believe). Thus was the imprimateur of the artistic elite stamped on the pedophile. Like a break in the dike, the pre pubescent girl became all the rage on the streets and even in strip bars. Nice.
And how I did I manage to ignore Larry Clark's oeuvre? He deals almost exclusively in young-teen sex.
