I don't know why this kooky little film hasn't received better notices. As a huge fan of both Groucho Marx and The Voice, "Double Dynamite" was a dream come true. Groucho hasn't been this funny since "Duck Soup," and Ol' Blue Eyes plays off him beautifully. If there's a complaint here, it's that there aren't enough musical numbers. "It's Only Money" (a duet between Frank and Groucho) is a show-stopper.
