Alice Tripp is wearing different shoes when she starts walking home from the movie with George Eastman than she is when they are close to where she lives. When Shelley Winters pointed out to director George Stevens that the brown and white shoes she was wearing turned to black when she walked around the corner, the director refused to reshoot the scene. According to Winters, he said, "If they're looking at her feet, I can go home."
George Eastman walks out of Loon Lake with his clothes and hair soaking wet; minutes later, when he stumbles upon the boy scout camp, he is all dry.
During a one-on-one conversation between George and Mr. Vickers, George explains his family background and why he wishes to take care of Angela. He is clearly seated to the left of Mr. Vickers. Several close-up reactions reveal Mr. Vickers speaking towards his right side.
In the boat, the collar of Alice's dress keeps popping in and out of her coat lapel. In the closeups, it's on top of the coat; when shot from George's side of the boat, it's under the coat.
George is at the billiard table when Miss Vickers enters the room. She wants to watch him play. George then aims at a colored ball close to the right cushion, when in a previous shot he cleared the table, leaving only the white ball at the top left corner.
At Loon Lake, when George and Angela hear a loon, they look up into some trees to see the bird. Loons are never found in trees. They nest on the ground near lakes and live on the water. They are solely aquatic birds.
A condemned's head is shaved before execution via the electric chair. As George is being led to the chair, his head is unshaven.
In prison when George is supposed to walk the last mile, the warden asks him to come out, and there is a long pause. Someone is walking by in the background and begins walking in slow motion for the duration of the pause, then resumes normal speed. Clearly, the shot of the warden standing there was extended by putting the film in slow motion.
At the Vicker mansion, after learning that George is suspected of murdering Alice, Angela is escorted to her room by her mother and Lulu the maid. Angela collapses on a large oval hooked rug. As the camera pans to her mother, an open space in the mirror to the left can be seen where the camera is filming from outside the room "through the wall" and into Angela's room.
Earl mentions "Something more intimate maybe?" Upon Angela's entrance, she replies, "Did I hear you were getting intimate, Earl, darling?" Her lips are not saying this line.
Angela Vickers arriving at the home of George Eastman announces something but what she says is not what was filmed.
Once George Eastman is convicted, it seems like no time at all before he is led to the electric chair. His attorney should have appealed the conviction.
The convertible that George and Alice leave open all night in the pouring rain would be swamped with water the next morning when George leaves Alice's apartment.
