When "Nick Allen" (Billy Dee Williams) waits outside for "Esther" (Janear Hines) to leave her place of work, she has on a dark colored blouse and her hair is draped around her neck to her shoulders. Then from an in-car shot when Esther is shown driving (checking her left rear-view mirror, seeing she's being followed by Nick), her clothes and hairstyle have changed: she is now wearing a white colored blouse and her hair is in a pony tail.
She pulls over for Nick, he gets out of his car, walks to the driver side of her car and her clothes and hairstyle have changed back to her wearing a dark colored blouse and her hair draped around her neck to her shoulders.
