Standing in the rain at Maria's funeral, Harry's raincoat is notably more drenched before Oscar's dissertation than afterward, when the lapels are suddenly dry.
When Harry first meets Maria in her dressing room, her blouse alternates between being on her right shoulder and then down on her arm.
When Dawes is speaking to Maria about coming to America, her blouse first only has one button undone. About half-way through the scene, a second button is undone.
When Harry is talking to Maria, outside of her house, for a moment he is with his left hand in his coat lapel and his right hand holding the cigarette. The next shot shows him with his both hands in the pockets.
When Maria is sitting at the table meeting Kirk Edwards for the first time, her blouse under the shawl changes from lower to higher up on her shoulder.
Just after Maria's engagement is announced, Harry is in a small town near a seaport talking to a group of men. They are all looking and gesturing off to stage left. Maria drives right up behind the group and sounds the car horn. The group of men continue talking for almost 3 seconds before any of them react to a car horn that is supposedly going off just 5 feet behind them.
After Maria is dead, she still blinks her eyes; most noticeably the first time, when she moves her right eye just after being laid down.
As Vincenzo is driving in his convertible, just prior to seeing Maria dance with the Gypsies, a piece of the camera rig is briefly visible.
