Stars: James Spader, Maggie Gyllenhaal

Of all the films in this list, Secretary might be the most potent, inspiring not just sex, but rough sex. The tale of boss Edward (Spader) turning his mediocre new secretary Lee (Gyllenhaal) into a submissive BDSM partner is so perfectly told that it's caused many a woman to change her thinking about that sort of thing. It's like 50 Shades of Grey, but without being the fucking worst to take over the nation.
