when they redid the ratings to add pg-13 in 1984 bare female breasts disappeared from all but r movies. i do not remember a pg-13 movie that actually has them in it and as i am looking this up, Titanic is about the only movie i know of that was pg13 and had nudity.
we can blame lucas and spielburg for pg13...indiana jones and the temple of doom temple scene- the heart being cut out scene i believe- was deemed too violent for pg yet the movie itself was too tame for R
hey can we list Indiana Jones and the Temple of Doom here ? cheesy- check- not great- check- 1980's? check. of course i'd watch it over a lot of the movies here, but....
