She'd been appearing nude in many more films before (and indeed has since), but it was her quick leg uncrossing in Basic Instinct that put the lovely Ms. Stone on the list of Hollywood actresses that were very comfortable with nudity, and propelled that film onto a special list of iconic film moments that completely transcend their context. But with the prevalence of that particular scene, those who haven't seen it might not know that she does a lot more than just flash Michael Douglas and his cohorts under interrogation.
26. Witness Kelly McGillis
In Witness, Harrison Ford is a cop hiding out in Amish country after he is wounded trying to protect Rachel (McGillis) and her son from rogue cops that want to kill all of them. We spend a good portion of the film learning how the Amish culture and the rest of the world don't mix, with inevitably sexy results. And that makes the scene where Ford finds her taking a sponge bath that much more exciting.

If you like your breasts animated, you should check out this 1981 R-rated cartoon anthology, which took its stories from the pages of the (then) monthly adult art magazine, as - somewhat typically - there is plenty of animated flesh in the Harry Canyon, Den, So Beautiful and So Dangerous and Taarna sequences.
