Continuity mistake: When Esther is confronting the King Xerxes and Haman at dinner, her necklace disappears and then it reappears on her neck.
Visible crew/equipment: When King Xerxes appoints Haman as his Regent he taps the scepter on Haman's signet ring, then there's a brief shot of Esther running in the rain, and in the next long shot we can see a crouching crew member, who's wearing a watch, at the lower, left side of the screen. This person is a bit visible in an earlier shot from the same angle. (01:41:05)
Visible crew/equipment: After Haman lies to Esther about the two eunuchs, Esther and Hegai walk away leaving Admantha standing alone, and in the last shot from behind Admantha, there are two white T-marks visible on the ground near his feet, at the bottom of the screen. (01:04:40)
Continuity mistake: During Esther's banquet when she is pleading her petition, Xerxes has a dagger tucked into the front of his golden belt, but while Esther is holding the necklace in her hand, in two shots facing Xerxes the dagger is gone, and then it returns. (01:49:50)
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)
Answer: No, Xerxes does not kiss her forehead because you see shortly after that, she is still asleep then wakes up. If he had really kissed her she would have felt it and woken up right then.
