I don't know why this film isn't rated higher... I rank this as Brook's BEST film. Great direction and production, good script, perfect casting, and fun even if you don't catch all of the Hitchcock references. I don't know why people think Brooks shouldn't have played the main character... he IS Dr. Richard H. Thorndike! He looks like a mild mannered Jewish psychiatrist who gets a bit wacky at times, even letting loose at a piano bar. Excellent film.
