He wasn't there.
The dance performance by four members of the troupe was sick though, I will post some vids later.
The movie itself was everything I had hoped it would be. I don't think Noé will ever outdo Irreversible solely because of its massive sledgehammer impact but this came goddamn close. The two black guys had me rolling (one of them was also part of the dance performance and Q&A and that guy's charisma and energy is infectious), the dance scenes are glorious and once hell begins, Noé reigns. Can't wait to see it again next week in the biggest (sold out) screening of the festival.
