I hadn't heard about Mr.Carey's passing.Sad.
As you say,it seems all of Ford's "stock company"are gone now.Perhaps the only exception is Maureen O'Hara(you can't keep a good Irish redhead down).
All within living memory,but somehow this style of film-making seems as far away now as that of the silent era.
I had heard that that famous "holding one arm"stance The Duke adopts at the end of The searchers
(with Jeff=Pike Hunter)was a tribute to Harry Carey Snr.who often stood in that pose.
