It was not until the ubiquitous car chase with the inane traffic cop that I realised that I had seen this film before many years ago. Being a concoction of suspense and humour, in my opinion, this is rather more of a family film than the usual nail-biting Hitchcock suspense, such as "Psycho" or "Vertigo".
I was particularly taken by Barbara Harris, who plays the phoney psychic, Madam Blanche and, to my mind, provides much of the humour. The "wink" she gives to the camera at the end of the film provides another form of "suspense", leaving us wondering whether she perhaps really does have psychic powers.
I am glad that I purchased this film and recommend it for its mix of entertainment.
