The Man Who Knew Too Much is a 1934 suspense movie directed by Alfred Hitchcock and released by the Gaumont British company. It was one of the most successful and critically acclaimed movies of Hitchcock's British period.
Hitchcock remade the movie in 1956 for Paramount Pictures, the only one of his movies that he ever remade. The two movies are however very different in tone, in setting, and in many plot details.
