The video of Ann that John saw was different from what the audience saw when she was recording herself.
When John forcibly rushed into Gulahan's residence and looked for Cynthia and Ann's tapes in the box on the table, he could see that the dates on the two tapes were the same. The viewers had already known very clearly that Cynthia had recorded her tape several days ago.
When playing the videotape, I feel that the camera is constantly moving, as if the camera was held in hand during the interview; and in almost all interviews, it can be seen that the Gulahan fixed the camera before starting the interview. In front of the respondent.
Continuity: When Ann first visited him at Gulahan's house, how much iced tea was in Ann's cup. When he handed it to her, it was half full, and then you could see that it was almost full, and she almost overflowed the ice tea.
The view from the window of John's office is different from that at the end of the film
