Continuity mistake: When Prince Henry kisses Danielle at the old castle ruins, just after she has had threatened her oppressor and left the castle, his hand switches from under her arm to over her shoulder. (01:20:40)
Continuity mistake: In the first scene, the king asks Henry "what's this about a servant". During this shot he takes a few steps forward. Then the scene cuts to Henry and we can see the King in the background, again taking some steps forward and saying something, yet nothing can be heard. (01:22:40)
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)
Other mistake: In the scene when Henry walks over to pick the glass slipper off the ledge it starts raining. All his clothes get wet, except his hair, which stays perfectly dry... (01:36:15)
Continuity mistake: Just before Danielle is sold, she has a conversation with her evil stepmother in a narrow pathway in the garden. In the shots of the stepmother speaking, her hands are on her hips but when the shot changes to Danielle, so we see the back of the stepmother, the stepmother's hands are not on her hips anymore until the shot returns to her front. This goes back and forth a few times. (01:37:50)
Visible crew/equipment: The morning after the masque, when Danielle and Rodmilla argue, as Danielle responds, "Is that what I am? Your Problem?" her T-mark is visible on the grass at her feet (fullscreen version). (01:38:10)
Visible crew/equipment: The morning after the masque, after Danielle shouts, "I have done everything you have ever asked me to do, and still you've denied me the only thing I ever wanted," in the next shot facing Rodmilla as she walks forward, her white tape T-mark is visible on the grass behind her. (A bit of it was also visible when she first approached her mark.) (01:38:25)
Continuity mistake: When Henry stops the wedding and allows the Spanish princess to run to her real love, there's a shot where he's taking off his cape. When it switches to the shot with Henry in the background as she's hugging her real love, Prince Henry is just starting to take off his cape again. (01:43:10)
Continuity mistake: When the Prince proposes to Danielle, in the shot from behind her, her long hair is pulled forward in front of her shoulders, but in the shots from the front her hair is behind her shoulders and she did not touch it. (01:47:05)
Visible crew/equipment: Near the end, when Rodmilla and her daughters are requested to appear before King Francis, in the first shot facing the king and queen, there is a beige narrow mat in front of the large patterned rug, which is not in previous or following shots, specifically used for crew/camera tracking (fullscreen version). (01:50:30)
Continuity mistake: At the end when the court bows to Danielle, in the wide shot you can see Jacqueline curtsying. But when it cuts to the closeup of Marguerite who's standing next to her, you see Jacqueline drop down into her curtsy again. (01:52:30)
Visible crew/equipment: After the Baroness is stripped of her title, Danielle makes her entrance and everyone bows. When her stepmother has turned to face her, as everyone rises the actor's T-mark taped to the floor is visible to Jacqueline's right, behind the former Baroness. (Only visible on fullscreen DVD.) (01:52:40)
Revealing mistake: When the Grimm brothers' carriage pulls away from the castle, after Danielle's story is told, at the top right side of the screen, there is a moving white vehicle driving toward the left side, at 01:56:42 (viewed on a tablet). Then, just before the screen fades to black, a blue car with a white top (and a couple more nondescript), can be seen parked in front of the building with a brown roof, at the bottom of the screen towards the right, at 01:56:57. (01:56:35)
Continuity mistake: At the manor, when Leonardo da Vinci hugs Danielle and says, "Think of it as a belated wedding present, Your Highness," the distinctive wood chair (more are all over the manor) is under the side window behind him, also visible as Danielle takes Henry's hands and pulls him towards the alcove with the two windows. Next shot, however, that chair is gone from behind Danielle (where the side window is) and there is only a wood table in front of the center window (fullscreen version).
Continuity mistake: When Prince Henry lowers himself out the castle window, the tied bed linens hang through different sides of the divided window, between the exterior shot of Henry and the interior shot when his parents discover his escape.
Audio problem: In the scene where the Prince meets up with Leonardo da Vinci for the first time and notices that his guards have found him, he says 'Oh, I can't believe this'. His mouth isn't in sync with what he's saying.
Suggested correction: Firstly, the closed captioning reads, "God, I don't believe this." Second, Henry actually says it twice - the first time his mouth IS in sync with what we hear, but then he mouths under his breath "I don't believe this," again, in annoyance with the situation.
I am watching the scene right now, and his mouth really isn't in sync. In order for him to say the word "believe" (even in mumbled form), he would have to move his mouth to form the "b" sound, and he does not at that point.
Continuity mistake: When Marguerite claims to find the necklace and pendant that the Queen dropped, as she hands it to the Queen, first she holds the pendant in her open palm, then pinches it between her fingers, then again in her open palm.
Continuity mistake: At dinner, when the Baroness complains about it being too dark and accuses the help of stealing the candlesticks, in the first shot the two candles in front of her are about an inch high, but much taller in following shots.
Factual error: Leonardo da Vinci came to France in 1516 by the King's invitation and died there in 1519. Prince Henry would have just been born around that time. He appears least 20 years old in this film.
Factual error: Chocolate started getting known in France in the 17th century, under Louis XIV. Since the movie takes place about a hundred years before that, Marguerite eating it is an anachronism. Even if she somehow got hold of some, at first chocolate was only a drink - it took a while longer before people started eating it.
