World cinema is getting bolder every day and you obviously cannot talk of bold cinema and overlook those films where they took method acting a notch higher while filming sex scenes. I'm talking about films that showed sex scenes, where the actors actually had to strip and perform real sex on-screen. Any working actor will tell you their career requires being open to some crazy things. Having to film a love scene can give even the most courageous and reputable actors some stage fright. But imagine if you had to do it for real?
I mean, full on penetrative intercourse. You'd think it would be illegal, but plenty of movies have incorporated real sex between actors in order to establish a sort of genuine authenticity to the film.
