Just before Bridget sees the fuel gauge is empty, she is smoking. After cutting to the close-up of the gauge and then back to Bridget, her cigarette has disappeared.
The ruffled look of Bridget's hair throughout her love scene with Mike is inconsistent.
When Bridget/Wendy Kroy deliberately crashes into a pole, ejecting Private Investigator Harlan out of the front windshield, the vehicle never crashes into the pole. In real life, the hood would be severely dented and there would be a large indentation where the post hit. In the film, presumably a mannequin is propelled out of a sugar glass windshield with the vehicle not moving.
