The story arc in this episode involving Inspector Pazzi (Fortunato Cerlino) is identical to the Inspector Pazzi (Giancarlo Giannini) story in the movie, to the point where the dialogue is exactly the same in both.
La Gazza Ladra by Giaocchino Rossini, used for the fight scene in this episode, was also used for the scene wherein Moriarty executes his plan. In both, the music is used to accompany a tightly choreographed and consequential series of movements in a pivotal scene.
