In the wide shot of the car, sky and for sale sign when Larry is looking at the property for sale the night sky is tiled. Two copies of the constellation Scorpius can be seen, one on the left and the other slightly fainter at far right.
When Don, Charlie, and Larry are sitting in a room in the house talking, a shadow becomes visible in the doorway behind them. Right before the scene changes, a member of the crew's foot is visible as they begin to walk within camera range.
