 The name of the films production company (Blue Parrot/Bad Hat Harry  Productions) is an inside reference to a line from  _Jaws (1975)_ (qv), where Brody is mocked by an old guy in a black  bathing cap on the beach and greets him by saying "Thats some bad  hat, Harry." The "Blue Parrot" part is a reference to  _Casablanca (1942)_ (qv), as is the title of the film.
