These days, polyamory isn’t just for kooky Bushwick types. Legit Hollywood stars are spicing up their on-screen marriages with ménages. The plot to each of these movies playing at the Tribeca Film Festival is basically one big build up to a group sex scene. (Spoiler alert: now that we’ve said that, even seeing their titles will give away their, uh, climax, so read on at your own risk.) Whether it’s a vanilla foursome or an incestuous threesome you’re looking for, Tribeca has it all.
