HYSTERIA (1964 Hammer Thriller) - Used VHS

Hysteria works primarily because of the swinging sixties atmosphere and the mysterious plot, which is played to the maximum and finishes with a great twisted climax. It's amazing that this film was produced by Hammer studios, as it feels much more like a Hitchcockian mystery/film noir than anything else that the studio produced. The plot follows an American who wakes up in an English hospital, unable to recall what has happened to him and how he got there.
