Factual error: Towards the end of the movie when the Titans are playing for the championship, Petie grabs up a fumbled ball and runs with it. When he stands up from being tackled, watching TV back in his hospital room, Gary yells Petie's name and the nurse comes to Gary's room to see if everything is all right. When she opens the door to Gary's hospital room, she opens it into the hallway. There isn't a hospital in the world where the patients door opens into the hallway. They all open inward to the patient's room.
