Reagan played George Gipp (the Gipper). Can’t recall any speech he made in the movie except on his death bed. Rockne was played by Pat O’Brien. It was Rockne’s speech, “Win one for the Gipper” that is most remembered.
Believe it was the “Win one for the Gipper” part that was cut out of some TV showings back then. All rather petty and silly though, lol.
