The movie was nominated for, and won, one Academy Award in 1957, for Best Music, Original Song to Jay Livingston and Ray Evans for the song "Whatever Will Be, Will Be (Que Sera, Sera)".
Because it is Hitchcock's only remake, it raises the issue of the superiority of his American work to his British productions. Though the original 1934 version is witty, the remake is more lavish and expert, containing some of Hitchcock's most powerful scenes in widescreen VistaVision and Technicolor.
James Stewart, a favourite of Hitchcock's, plays an American doctor, Ben McKenna, on holiday in Morocco with his family, who accidentally learns of a political assassination which is to take place in the near future. A friendly English couple are in fact spies in on the plot, and they kidnap Stewart's son Hank (Christopher Olsen) to ensure his silence. So Ben must prevent the killing without putting his son in harm's way.
As in most Hitchcock films, the international intrigue is less important than the odyssey of the hero. Stewart indeed 'knows too much,' not valuing the capabilities of his wife (Doris Day). As the plot unfolds, however, her assistance proves essential, despite his fears of her emotional collapse (he even drugs her before telling her of the kidnapping).
The film climaxes in the Albert Hall, one of Hitchcock's best-ever set pieces. 'The Man Who Knew too Much' features excellent performances by Stewart and Day, and by Bernard Miles and Brenda De Banzie as the British agents. The score by Bernard Herrmann, who appears in the film directing the orchestra, is one of his best and the performance of Arthur Benjamin's cantata 'Storm Clouds', unchanged from the original 1934 film, is the climax of the movie.
