When Ethan Edwards (Rider Strong) is being interrogated, there is about a 5 second period of time when you are watching Goren interrogating him and Edwards answering a question from the other side of the glass where the other officers and the D.A would be watching them. In this part of the scene, you can see through the glass that the words Edwards is saying are not matching with his lip movements.
