I want to know the answer to the following question:
Pat O'Brien portrayed which person in the film Knute Rockne?
All the background I'm provided with is that "The song also was prominent in the movie Rudy, with Sean Astin as Daniel "Rudy" Ruettiger, who harbored dreams of playing football at the University of Notre Dame despite significant obstacles.". Is that enough to answer the question?
Answer: no
