Being a life-long Irish fan, I really loved the movie. Just recently I read an article in the Legion magazine about Rudy. Turned out the writers of the movie skipped over a significant fact: Rudy spent some years in the U S Navy before applying at Notre Dame. He was a yeoman on a communications command ship.
Interesting. The movie only shows that he worked at the steel mill with his brother and father. Wonder why they left that out? Hollywood ;(!
