An overlong Hitchcock. Doris Day is fine on the acting front but her character is flimsy, especially when histrionic; she's at her best playing the wife, duelling with Jimmy Stewart, and so much less interesting when impetuous or motherly. There are some good camera angles in the Albert Hall but much of it has Doris more-or-less helpless, rubbing her brain cells together. It is not particularly edifying.
This was Hitchcock's second bite of this cherry.
