Coppola's The Cotton Club has a definite undertone of bdsm - Dixie Dwyer the innocent young cornet player (Richard Gere) and Vera (Diane Lane; his love interest, but as they both know she's also involved with gangster bigshot Dutch Schultz) are both used at the mercy of Schultz. "You don't belong to me; you're Dutcj's property" Dixie says at one point as Vera is trying to get him up to her place and into bed after a nerve-racking incident. She humphs and disappears behind a big iron-grille gate, like into a cage.
Great movie, too, brilliantly acted and cut - and unlike many gangster movies it aims to give a kind of rounded picture of Harlem and the NYC gangster world in the late '20s, without losing speed for that.
