If you think the movie Nana (1982) is about a sweet old grandma, think again! Also known as Nana, the True Key of Pleasure, this skinternational flick is based on Émile Zola’s risqué novel “Nana” (1880). Foreign catch Katya Berger takes off her clothes while taking on the titular role. Under the direction of Dan Wolman, the English-language Italian production celebrates the exploits of a wily Parisian prostitute as she employs her natural resources to raise her standing by climbing the proverbial social ladder. In other words, the flexible fox figuratively swings her fit figure upon the tumescent monkey bars protruding from all of the most prominent men of the town whenever they step into her proximity. Set in the 1800s, this period piece shows us that the highest reaches of society can be scaled and subdued by a properly equipped chick, if she has pluck, luck, and a willingness to doff her duds. As such, a demure Nana bares her breasts while being bathed by her nanny just six minutes into the flick. Wait another seven minutes, and you’ll get to see the alluring actress’s three Bs! In fact, the aptly-named Ms. Berger bares her bush, boobs and booty throughout the movie! Not to be upstaged, sexy Sabine (Mandy Rice-Davies) also shares her naked chest on screen when she kisses a guy while her husband watches. Kinky! In 2001, Edouard Molinaro retold this tale with his same-named adaptation starring Lou Doillon. It just goes to show Nana is a timeless tail!
