Continuity mistake: When Bob is in the coffee shop waiting on the call from Dr. Marvin he chases an older man away from the phone. The rope for the fish jar hanging around his neck is twisted around once or twice. The camera cuts away from him then back to him and then the rope is twisted around seven or eight times.
Continuity mistake: When Leo starts coughing, we see Anna start to get up and go to her right, meaning that she'll pass behind her mother's chair. It then cuts to Siggy for literally a fraction of a second, then to the mother. But Anna is never seen in frame behind her mother at any time.
