Errores

At the cottage, when Stedman is entering the upstairs window and the view changes from outside to inside, the window is suddenly open far wider than it was previously.

When Catherine steps into the road in front of an oncoming car, that shot was filmed elsewhere, as can be seen by changes in the brickwork of the wall behind her. The wall in the car shot is, in fact, just like that on the opposite side of the street at the point where Catherine is walking immediately before the near-accident (junction of Princes Road and Broomfield Road, Richmond, Surrey, UK).

In the final scene Alex is told that Catherine won't say a word to anyone. Ales goes into see her and she starts talking to him. But the nurse sitting in the room doesn't seem to notice or react at all, despite this being a significant change in the patient.

While on the beach, young Catherine is telling Alex that she knows the names of her father's patients. We hear her say she knows "four" names, but her lips show she is saying the word "five". Likely, "four" was dubbed over "five" upon the decision to remove Patricia Neal's character from the story.

Alex Stedman's accent is clearly not American.
