Both actors used body doubles for the hard-core sex in that movie. Body Double For Ms Gainsbourg: Mandy StarshipBody Double For Mr Dafoe: Horst Stramka
Actually it is a body double, a porn actor. But great rip. The director (Lars von Trier) joked in an interview that Dafoe was to big and would have scared the audience :-)
Well, this is not him or even Charlotte Gainsbourg, but body doubles.
come off it mate, mainstream actors don't do porn except Kieren O'Briean. They were porn actors. The film was a total flop unsurprisingly.
Yeah, that movie was horrible. Even the sex scenes were horrible... especially when she cut off her own clitoris with a pair of scissors...
Director Lars Von Trier said that Dafoe's cock had a "stand in" for the film "Antichrist": "He has an enormous dick, extremely well-equipped. And we had to kind of take the scenes out of the film, we had a stand-in for him, we had to take the scenes out with his own dick because Will's own was too big. Everybody got very confused when they saw it."
