Those reruns of Hopalong Cassidy are running now on the Silver Screen channel. Mitchum is usually one of the bad guys. The cast stayed pretty much the same only changing roles. Gabby Hayes is in some of them.
Hubby actually met William Boyd when he was young, in Ocean Falls of all places. He got off the boat while it was docked unloading supplies, all the kids were gob smacked seeing their hero in person.
