What's the Significance of Frank James (James Brolin) At the End?
SPOILER
At the end of the film, we see adult Mattie go to the Wild West show where she learns about Cogburn's death. James Brolin has a cameo as Frank James. She gives him a glare and says "Keep your seat, trash." The first time I saw this, I was completely confused by that and wondered who he was and if he had been a scene earlier in the movie. I had to go to the movie's Wikipedia page to find out who Frank James was. What's the significance of Frank James being there and her disapproving of him so much? Was he mentioned earlier in the movie at any point? It just seems random.
