Which film did Alfred Hitchcock make twice?

Alfred Hitchcock made his own film The Man Who Knew Too Much twice. The original film was released in 1934 and the remake was released in 1956.

Alfred Hitchcock revealed in the book length interview entitled Hitchcock (by François Truffaut) that he considered the 1956 remake superior to the original. He said he felt that the 1934 version was the work of a talented amateur....while the 1956 remake was the work of a professional.

It seems Hitchcock was not completely satisfied with the original and felt that he could make the film better. This does make sense since there are some differences between the two films. Basically, the remake is done in color, and it has an American cast instead of a British cast. Also, a couple of scene locations have been changed. Still, the two films have the same plot, and each is a suspense thriller.
