 The staging of the climactic sword fight between Justin and Jenner  was largely taken from the Errol Flynn/Basil Rathbone duel in  _Adventures of Robin Hood, The (1938)_ (qv). (Some choreography,  including the villain getting stabbed in the stomach, was literally  copied by the animators.) Other moments were inspired by fight  scenes in _Vikings, The (1958)_ (qv).
