In Conagher, the young kid had an 'Improved Henry' (66). Of late, Henrys have been used in a LOT of movies, and it's now kind of hard to recall them all. In 'The Avenging Angel' Tom Berenger used one. In 'Ride with the Devil', Tobey McGuire used one. There was another movie called 'Rio Diablo' with Kenny Rogers, Travis Tritt, and Naomi Judd, and I believe Travis Tritt carried one in that movie. In one of the later episodes of 'Young Riders', Henrys appeared, a time or two. Let's see...Silverado, Lonesome Dove, Desperado, and Last Stand at Saber River have already been mentioned.
Oh, there were two or three movies called 'Black Fox' that starred Christopher Reeve, and they were dealing with 'Britton Johnson' a noted black Texas Frontiersman....they used some Henrys in there. There are a few others...if something comes to mind, I will add the info....
