...Barry Corbin's character in the story? He was the guy who Tommy Lee Jones' character met at the diner that was off to see the grandkids with the wife in the RV. They were old army buddies, but other than that I couldn't see why that scene was in the movie.
"check the imdb cast list before asking who portrayed who in movies please"
The only answer comes to mind is that this film served as a No Country for Old Men cast reunion. I was disappointed that Javier Bardem and Woody Harrelson couldn't make it.
He killed sixteen Czechoslovakians. Guy was an interior decorator.
I think it was an attempt to show Tommy Lee as dated and out of touch, because Barry had been retired for more than a decade which he had to remind Tommy Lee of, in addition to telling him nobody on the base they knew still worked there.
I think there was a not very well executed motif in the film about the lost honor of soldiers, and this was meant to demonstrate the gap between generations of soldiers.
He made reference to seeing his grandchildren, Tommy Lee Jones' character knows he will never have grandchildren. The expression on Jones's face is heartbreaking...
