Woody Allen places a large gumball machine in one of the opening scenes to create a link between his character, Winkler, and fellow inept criminal Virgil Starkwell from his other film Take the Money and Run.
The film contains several references to Sir Arthur Conan Doyle's short story 'The Red-Headed League,' including the plot to break into a bank through the basement of an adjacent storefront and Frenchy's attempt memorize the contents of the dictionary.
