Continuity mistake: Romeo has a jacket on which magically disappears, during the love scene near the end. (01:20:00)
Continuity mistake: When Romeo gives his hand to Juliet on the balcony before descending, he gives his right hand to Juliet. Immediately his left hand is shown in Juliet's, then his right hand is shown in hers again.
Chosen answer: The movie was filmed in several cities: Subiaco, Mantua, Caprarola, Lazio, Rome, and Verona.
