Continuity mistake: In the scene where Doug and his brother are talking outside the cemetery, the zipper on Doug's jacket goes from being almost completely zipped to about halfway zipped without him touching it.
Factual error: The establishing shot when Doug takes Claire to visit the assistant manager is set (like the entire film) in Boston, but the shot shows the City of Angels Medical Center (now the Silver Lake Medical Center) in Rosemont, Los Angeles. Unfortunately, its name is emblazoned all over the exterior wall.
Continuity mistake: In the scene in the laundry room Claire thinks back to the bank robbery when she would have gotten blood on her blouse. The recall shot shows her standing in the bank wearing the blouse. In the original shot during the robbery she was laying on the floor wearing a black jacket and would not have gotten blood on the blouse under the jacket.
Continuity mistake: When the gang use the black car, they have a collision with a police cruiser and the driver's side headlight and wing is crushed. During the chase that follows, however, there is a brief shot of the car going around a corner and the headlight and bodywork is now intact again, and in the next shot is back to being damaged.
Continuity mistake: In the scene where Doug and Jim go beat up two strangers, who Claire accused of harassing her on her walk through the projects, the door is closed. Right as Doug gets up to leave, the door is open, and the door is closed again when Jim shoots the bully in the leg and they leave the apartment together.
