However, Marines and members of the United States Navy are sent to Portsmouth Naval Prison in New Hampshire. It is run by the Marines.
Factual error: At the very end of the movie, the Pope gives the nuns a standing ovation. The other people seated in the box with him should have immediately risen at this time.

Factual error: In District Attorney Trotter's opening statement he asks the jury to convict William Gambini of murder in the first degree and Stan Rothenstein of accessory to murder in the first degree. There is no such crime in the Alabama criminal statutes. It has to be either Capital Murder or just Murder. Alabama does not have different "degrees" of murder. Also the arraignment and trial are both conducted by the same judge. In the Alabama court system a District judge would have conducted the arraignment, while a different Circuit judge would have conducted the jury trial. It's ironic since the director brags about his attention to detail in the DVD director's commentary. He obviously didn't check it too closely.

Factual error: In the scene where Redford's character enters through the secured entrance with the stolen key-card, it shows a printer printing the time he entered. Then after his walking and getting up to the top floor and trying to get past the voice verification system and having to do it twice, they show the same printer printing the time he passed that checkpoint, and it was only one minute later than the previous time. Even though seconds are not shown, all of these actions must surely have taken longer than 1 minute and 59 seconds.
