Ingrid Bergman's excellent performance is what makes this film. She sincerely deals with the problem of September love; I've never seen her more beautiful or more committed. Anthony Perkins as the young spoiled mama's boy is excellent, and the scenes with the two of them are very believable. (It's called acting) Yves Montand is terrible---he's longing to be speaking in French. The scene at the end between Bergman & Perkins from the top of the stairs could move a stone to tears. Only Bergman could convincingly pull off a perfect soap opera--there will never be anyone like her.
