I haven’t seen the movie, but Hitchcock had a reputation for disrespecting women, maybe because of marital problems. There is a scene in Frenzy where a couple meet at a matchmaking service and the woman immediately starts telling the man that he has to change. According to one documentary, Hitchcock often portrayed women as controlling.
I watched Hitchcock last evening. http://en.wikipedia.org/wiki/Hitchcock_%28film%29
Not sure how much is factual but now I need to watch Psycho again. The story centers around Hitchcock getting Psycho filmed and produced. And I sure do feel old because I remember watching Alfred Hitchcock Presents on TV.
