I was watching the original The Day of the Jackal starring Edward Fox as the Jackal. There is a scene where the character Denise is shown in bed with her boyfriend, whom she is using to gain inside information on the French Government.
As the scene progressed, we see both her breasts, nipples included. She then sits up out of the camera's view and pads away silently, whereupon we are greeted with full ... err.. reversal ... nudity. Anyway, whatever the opposite of full frontal nudity is. Head to toe, nothing on. I wasn't ready for it, and I didn't remember seeing it previously, but no worries. I like a little skin.
However, I noticed that the TV Menu system showed the movie with a PG rating. I verified it on IMDB as well, PG. I'm sure that since the movie was made in 1973, it preceded all of the newer ratings (i.e. nc-17), but still even in the day, wouldn't that have gotten it an R?
