<p>Well, I agree that if she actually said she was recording it for a movie, that is totally weird and unacceptable. An interviewee should not be put in the position of feeling pressured to participate in something like that. </p>
<p>Contacting the admissions office and asking for another interviewer based on the fact that she apparently wanted to record interviews for a movie she was making is not a bad idea. They need to know that she is doing this–they will NOT be happy!–and you don’t want to give the impression that you don’t care about the interview. </p>
<p>I would do it by email, and be sure to make it very simple and straightforward. Don’t get into an explanation of how you felt or what you surmised. Just say that your friend informed you of this, and you preferred not to participate. They will understand.</p>
