In one of Hitchcock’s most iconic climaxes, THE MAN WHO KNEW TOO MUCH (’56) Composer Bernard Herrmann got to pull a “Hitchcock” and make an appearance in the film as the conductor. While Herrmann did not actually compose “Storm Cloud Cantata” played in the Royal Albert Hall, he did re-orchestrate the piece written for the earlier Hitchcock version—THE MAN WHO KNEW TOO MUCH (’34). | Turner Classic Movies: TCM
