With the exception of the brilliant The Court Jester, Knock on Wood must rank as the best of Danny Kaye’s movie vehicles. Capitalizing on the star’s recent successful engagement in London, the film casts Kaye as a neurotic American ventriloquist performing in England and Europe. In a parody of the 1946 thriller Dead of Night, Kaye is unable to control the words coming out of his dummy, resulting in a near-nervous breakdown.
