Factual error: Somewhere in season one Mary refers to Germany. But since this was set in the 16th century it would've been Prussia.
Continuity mistake: When Francis falls into the frozen lake he is wearing gloves, but when he is shown under the ice he doesn't have them any more. When Bash pulls him out he is once again wearing gloves.
Trivia: Anna Walton, who plays Diane de Poitiers, is only 3 years older than Torrance Coombs, who plays her son Sebastian.
Question: What is the name/type of dance that Mary and Francis perform to the orchestral version of Stay With Me?
