Other mistake: When Queen Marie tells Henry he was born to privilege and it comes with specific obligations, Henry says, "But marriage to a complete stranger never made anyone in this room very happy." Then, King Francis demands, "You will marry Gabriella by the next full moon." The problem is Princess Gabriella of Spain is named Princess Gertrude in the credits. (00:34:05 - 01:57:15)
Visible crew/equipment: After Auguste rides away the Baroness tells her daughters to go back to their lessons, and when Danielle says, "Wait, it's tradition," the Baroness stops and just as she turns the actor's mark is visible at he feet, in front of her gown. (Only visible on fullscreen DVD.) (00:09:30)
Visible crew/equipment: After Leonardo da Vinci removes the door's hinge pins to rescue Danielle, in the next shot as Gustave walks toward Danielle with his arms open, an actor's mark is visible on the floor precisely where Leonardo stops to speak to Danielle. (Only visible on fullscreen DVD). (01:26:45)
Continuity mistake: When Auguste dies, the Baroness cries, "No!" and puts her right hand up to her mouth, then uses both hands to shake him as she pleads, "You cannot leave me here!" Next shot her hand is back up to her mouth, but when it cuts again she is still shaking him as she pleads, "You cannot leave me here!" (00:10:50)
Continuity mistake: Danielle is given a lashing on her back which results in many scars, some of which are level with her shoulder blades (scapula). The next day, when she appears at the masque in the low-backed gown, what we see of her back is completely scarless, though they cannot have already healed.
Visible crew/equipment: When Auguste is leaving the manor he kisses the Baroness, and at the start of the next shot as he begins to speak to the three girls, the reddish actor's mark becomes visible in front of the Baroness' feet as her gown moves when she turns.
