Rudy - A Married Pete??
In the scene where Rudy comes home for Christmas, watch the part where Rudy is showing his report card to his Dad. In the background on the couch, we see Pete watching TV and wearing a wedding ring. Pete was not married in the movie. Obviously, the actor who played him was married and didn't want to remove the ring. During various other scenes, we see him without it and then with it again. Major IMO.
