Continuity mistake: In art class you see Mrs. Collins pick up some papers and a wooden tray, then turn and talk to Juliet. The wooden tray Mrs. Collins picks up has a circular carve in one end of it. In one shot she is holding the tray so the carving is facing her, then when the shot changes she is suddenly holding the tray the other way, so the carving is facing away from her. (00:08:55)
Continuity mistake: When Juliet drops the gem, Pauline then points it out and we see a shot of it. Then we see a second shot of it, as Honora picks it up. Between the two shots the position of leaves and twigs around the gem changes. (01:42:40)
