They did include Reagan's "Gipper" line. The Duke's long career didn't generate many memorable lines to be honest and those that do stick come from The Searchers, I think his best film, especially the visual coda.
>>> They included Pat O'Brian's line about Ronald Reagan. Perhaps this is close enough. My point about Ronald Reagan is that he went on to become President of the United States. You would think this would impress Hollywood, but it doesn't.
If you don't like my point about the Duke, consider that the are no lines from pro-war movies, not the line I suggested from "The Sands of Iwo Jima," and not anything from the greatest war movie of all time, "Patton," nor a line from "Braveheart." Yet, there's a line from the cyncially anti-war movie "Apocalypse Now" (which is a great movie, and should be represented in the list).
There was a time when "Angels with Dirty Faces" and "It's a Wonderful Life" were considered great films, with memorable lines. Yet, when reaching back in time, the panel latched onto only certain classics (and I have no quarrel with any of the older movies they picked, but I do have a problem with their selection of multiple quotations from a very select few).

The only segment I watched did show RR delivering the line as he lay in bed, then they showed the O'Brien reprise. And this was about writers, not actors.
btw...My original tag line was "Rocky Sullivan died a coward". I might go back to it.
