He was still one of the most popular actors decades after his death. He won an Academy Award in 1970 and should have won for the Searchers and Sands of Iwo Jima. The movie my avatar is from was directed by Otto Preminger. You are just petty jealous.
It's "Pawpaw" and I am 59 with 4 beautiful grandchildren. My daughter is a 26 year old Army officer and she LOVES John Wayne movies. She loves his cavalry movies and served her first tour as a cavalry officer. So do her nephews, my grandsons.
My father would come home from work after midnight on Fridays and stay up with me watching John Wayne movies that were on the late show. I can now almost do the movie's dialogue from memory.
I watch John Wayne movies from time to time. There are well over 100 of them, and plenty to choose from. Never get tired of them. Having lived in California for 12 years, and been a cowboy of sorts myself, I especially appreciate western movies and TV shows. Gunsmoke is still my favorite western.
Ask me about why cowboy clothes are designed the way they are. I know things about that, that few people do.
