According to the DVD commentary track, during the final scenes of the movie, writer/producer Daniel Moya was hiding under a blanket, behind the TV. He was there, listening in one ear to a scratch recording of the Nixon tape made earlier by him, the director and the script supervisor. Moya then shouted out audible cues to Willa Fitzgerald and John Magaro so that they could react and recite their lines at the right times during the scene while they were otherwise listening to a silent reel-to-reel tape. This way, the sound recordist, David Rosenberg, could record mostly clean tracks of production audio of the tape player and the actors moving around the room.

@ around 15 minutes when Paul & Connie are talking in the dinner a camera operator can be seen reflected in the mirror behind Connie. The camera operator is visible on the left side of the mirror before slowly moving to the right out of shot.
