Factual error: The movie leaves the impression that Huntsville, Texas and Austin, Texas are just a short distance apart. In reality, they are at least three hours apart.
Continuity mistake: When Bitsey is checking the videotapes at Dusty's house, the last tape, the one with the red label, falls over when she grabs the second last. As she puts the second last tape in the VCR the last tape is seen standing again. She then searches for any more tapes, but never checks the last tape.
Audio problem: When Constance informs David that he has been put on official "sabbatical" and unofficially released (as a professor), she adds vocally that the vote was "4-2". However, her lips do not move, and the exact vote turnout sounds distorted, because it was edited later.
Other mistake: Toward the end of the movie when Bitsy is racing to get to the prison before the execution, she has car trouble. She tries the key again before giving up, grabbing the video tape and running down the road. This same "car trouble and desperate race" scene is shown at the opening of the movie, but Bitsy exits the car immediately after it stops. There is no delay to allow for her to try the key again or grab the video tape.
Continuity mistake: When Constance and Gale are making love, she has zero bruises. However, both before and after the scene, there are many bruises - especially on her legs.
Revealing mistake: The video that Bitsey watches at the end of the movie, we see David walk over to Constance's dead body on the floor and Dusty walk away to stage left of the video camera. David then immediately turns around and walks towards the video camera, staring right at the lens. As he walks closer, the camera slightly pans down to keep him in the shot. The problem is nobody is running the camera. It was on a tripod on a table. Dusty would have to have done a quick 90 degree turn, stood on a chair and gotten set behind the camera in a very short period of time - without shaking the table or the camera.
Continuity mistake: When David is saying goodbye to his wife and son as they leave for Spain, he is standing with his hands on the open taxi door. From the front, he has the left hand on top of the right, but when shown from behind, the right hand is next to the left. This is shown several times during the scene. (00:49:05)
Continuity mistake: When David is talking to his son about when his mom will be home and what he can have for breakfast, the child's hands change position drastically between camera angles.
Continuity mistake: In Gale and Bitsey's last interview, Gale states that he will be dead by the same time the following day. However, the interviews were each 2 hrs and started at 3 pm, which would make it 5 pm when the interview was over. In the last scene, it is explained that all executions in Texas take place at 6 pm and Gale is pronounced dead at 6:12 pm.
