Continuity mistake: Doris and Tony are talking by the car. Two women walk behind them, talking, one with a blue coat, one with a grey coat. The camera turns to a close up, and the woman with the blue coat is alone. She then walks by them about 3 more times during this scene.
Continuity mistake: When Rex is explaining his ranch's layout to Jan over dinner, he uses a coffee cup, sugar cubes, and a napkin for props. The napkin initially obscures the view of sugar cubes, but when Rex returns to the table (after speaking with Jonathan) the sugar cubes are front of the napkin and in plain sight of the viewer.
