Revealing mistake: After the scene with the apothecary where the two eunuchs purchased the belladonna it then cuts to Esther, and in her closeup as she lifts the silver cup to drink, there's a small white modern sticker on the underside of the cup. (01:02:00)
Revealing mistake: They let us see the stunt double's face for the girl Steven Seagal is fighting in the ending Cathedral scene, and she looks nothing like the actress.
