Revealing mistake: At the beginning of the scene with Thena in the cave, she changes the weapons in her hand to two swords. It cuts to a closer angle, then another, and she (deliberately, not a mistake) switches one weapon to a curved blade. Cut to a wider angle, and someone forgot to add the CGI for that blade, because Angelina Jolie's left hand is gripping thin air there. (02:01:55)
