Factual error: At the end of the movie, they break out of prison and their lawyer finds them at the hangar. She tells them they are free and they celebrate and get in the car and drive off. Innocent or not, they broke out of prison. I highly doubt red tape would allow an official to say, "Oh well, never mind, we were gonna release them anyway."
Continuity mistake: When Harry says the word to trigger the bull, the bull runs out to him and has horns. But in another shot later, the bull has no horns.
