After a series of not so great to pretty bad films for Universal Studios, Hitchcock managed to put together a fairly decent film. For a man in his 70's and not in particularly great health this was a considerable achievement.
With a fairly decent British writer in Anthony Schaffer and a very good British cast, Hitchcock returned to London to film it away from the interference of Universal Studios.
The film is one of Hitchcock;s "run for cover" films something he had done successfully before, about a serial murder running around London strangling women. Hitchcock pulled it together for a couple of okay Hitchcockian scenes and the London locations did seem to invigorate his storytelling.
Frenzy is not up to some of Hitchcock's greatest films but it is a fairly good film to wrap up his career with, Family Plot excluded in this case. Running time 116 minutes.
