I hate to admit it, but I didn't find it to be one of Hitchcock's best but nonetheless a riveting, climatic thriller. In a remake of Hitchock's 1934 movie of the same title, Dr. Ben McKenna (James Stewart)  the man who knows too much - and his wife Jo McKenna (Doris Day) are holidaying in Morocco with their son Hank (Christopher Oslen) when there is a case of mistaken identity and caught up in the web of an assassination plot. The conspirators go to extreme lengths to prevent them from interfering with their plot: kidnapping their beloved Hank.<br /><br />I found it surprising that Doris Day, who I usually associate with Rock Hudson comedies, was cast in a Hitchcock film. As I was watching it, I soon realized that this was more of a family film compared to Hitchcock's other works (example: Psycho) and she had singing ability needed to pull off "Que Sera Sera", which she did beautifully. She was well cast as herself and James Stewart had chemistry, which helped make the couple believable.<br /><br />In comparison to the great director's other works I believe this isn't as good, but it is still a exceedingly entertaining family thriller/mystery. There is also the added bonus of Que Sera Sera, which turned out to be a smash hit for Doris Day. Well directed, well acted. A fine film.
