Double Dynamite is a 1951 American musical comedy film directed by Irving Cummings and starring Jane Russell, Groucho Marx, and Frank Sinatra. The film was written by Leo Rosten (story), Melville Shavelson (screenplay), Mannie Manheim (based on a character created by), and Harry Crane (additional dialogue). The film was originally entitled It's Only Money, before RKO owner Howard Hughes changed the title to Double Dynamite as a reference to co-star Jane Russell's famous cleavage.
