I’m sure I saw a b&w televised movie version that was so old that the extras were Civil War veterans — the English Civil War. :^) Maybe this one?

Not sure if I saw that one. Maybe it was on Turner Classic Movies. I remember seeing the 1975 TV film with Richard Chamberlain and the 2002 film version with Jim Caviezel.
Yes indeed...
I love movies based on a well-written story, and “acting” rather than “effects”...
