Brad Pitt: Alright, now the stunt guy here. No pads on the legs.
Edward Norton: Yeah, I've never been more scared than watching that guy.
Brad Pitt: Because we watched, he did the first time and everyone's amazed. Those stairs are hard. Everyone's clapping and then we just hear, 'once again!'
Edward Norton: And he did it eight times.
David Fincher: No, he did it twelve.
Edward Norton: Twelve?! No!
Brad Pitt: It was Fincher's sadism. And what take did you use?
