Loosely based on Anaïs Nin's French book of the same name, this 1990 flick was the first movie ever to earn an NC-17 rating, so you know it's hot. Henry & June revolves around a love triangle involving author Henry Miller, his openly bisexual wife, June, and Anaïs Nin, who carries on an affair with both Henry and June. As you might expect, a little bit of tension develops, and not just the sexual kind.
