This review of “A Mighty Wind” claims:
True? What was that line?
Just a guess:
“Hi. I’m Marti DiBergi.”
?
The entire scene with Patrick McNee was scripted.
In the director’s commentary for Best in Show, Christopher Guest explained that before they started each scene, the actors had a general idea of what was supposed to happen in it, and what information should be revealed, and that sort of thing, but they made up the actual dialogue as they went.
Thanks so far. Any others? Cites will be appreciated…
