Deliberate mistake: The tiny hot air balloon that Francesca released in the debate room would never be able to support Casanova's weight.
Continuity mistake: In the bedroom scene the bedding at the head of the bed slightly changes from one position to another and then back again.
Audio problem: When we first see Francesca and her family in their house, in any wide shots showing Francesca's brother, Giovanni, his mouth is not moving in sync with what he is saying.
Factual error: When Fabrizio arrives by ship you can see the cooling water jet coming out of the boat.
