There's a scene at Myerson's house in Savannah where Kendig is getting ready to start typing and sees a photo of Myerson. When the photo is first shown, Myerson is facing to the left of the screen, but when Kendig picks it up Myerson is facing to the right. The photograph changes several times later. In fact, each change is intentional, and is intended to show Myerson getting more frustrated and dour as the plot wears on, culminating in the picture being shot in the forehead (as explained in the introductory video on the DVD).
