In the long shot of the airplane, when Clementi's mother is arriving, the plane's open door can be seen to the left, but in a close-up shot the door is missing. Other features of the plane in the long shot do not match in close-up: the windows and the painted stripe on the plane, for examples.
At the beginning of the movie, Clementi visits his brother at his shop. At the door Clementi says, "Aren't you going to let me in?". The brother turns and leads the way. In the next shot, it shows the brother backing up to let Clementi in.
