For the show, almost nothing is scripted. For the movie, however, there were some scripted parts. Just the stuff with him by himself or with his Producer, though. Basically, you can mostly tell what's scripted and what's not. The scripted stuff is just to drive the story, but when he's interacting with people and doing interviews, that's all him. The people aren't in on it, and really think he's some crazy sexist anti-semetic foreigner.
And yeah, I can imagine there being TONS of cut footage. I really think a large part of the dinner scene was cut. Once he invites the prostitute over, and a bunch of people stand up to politely leave, they quickly cut to that one women telling him get out or she'll call the cops. Something happened in between because that escalated a bit too quickly.
