Continuity mistake: Before church services, when the Baroness and her daughters step out of the carriage they are met by the Royal Page, who has the hidden pendant. In shots facing the Baroness, he is holding his bag in his arm with its cord dangling, but in shots facing him that bag's cord is slung over his shoulder. (00:59:20)
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.
