His opening theme was written in Bachian organ andante, opening in D minor, for organ and an orchestra of strings and brass, and was intended to express the formality of the grey London landmarks, but Hitchcock thought it sounded too much like Bernard Herrmann's scores. According to Mancini, "Hitchcock came to the recording session, listened awhile and said 'Look, if I want Herrmann, I'd ask for Herrmann.'" After an enigmatic, behind-the-scenes melodrama, the composer was fired. He never understood the experience, insisting that his score sounded nothing like Herrmann's work. Mancini had to pay all transportation and accommodations himself. In his autobiography, Mancini reports that the discussions between himself and Hitchcock seemed clear, and he thought he understood what was wanted; but he was replaced and flew back home to Hollywood. The irony was that Mancini was being second-guessed for being too dark and symphonic after having been criticized for being too light before. Mancini's experience with "Frenzy" was a painful topic for the composer for years to come.
