When Arliss looks at the photo of Kay's family, the photo shown in the first shot is not the same photo as that shown a few seconds later in the close-up. In the close-up, the trees are gone from the background, the baby's hand is outstretched and you can clearly see the mother's face.
In a scene where Kay holds a revolver a bullet inside the cylinder appears, disappears and then reappears.
The tattoo on Arlis' forehead is missing several times.
