Continuity mistake: In the conference room, Frasier says, "I just said that," and the shot shows his arms resting on the table with his hands up, gesturing. The next shot, from the side, shows him leaning back in his chair with his arms right off the table. The shot then goes back to the original position. There was no time for him to move naturally.
Continuity mistake: When Frasier is in the boardroom with Roz and her production team, Frasier is writing in a binder, which is on top of a couple of books. In some shots we see a couple of different books in front of him on the table. One of them is called "Mars," which he had put back in his briefcase at the beginning of the scene.
