I'm looking for full movie marathons or parts of movie marathons for
John Wayne from the 1970's to 2006. I'm interested in the station's
promotions for the marathon in between commercials and especially TV
trivia sections or friends/family interviews for John Wayne which
TNT used to do.

Here are all the marathons I know of currently. I have a few from
2006 and 2007. I have only a small part of the 2007 AMC Centennial
marathon and missed some interviews:
