Saw The Count of Monte Cristo movie produced by a French studio, starring Pierre Niney which was released in 2024. It’s almost 3 hours long. Also watched the TV mini series with Sam Claflin that was released in 2025. It consists of 8 episodes. I enjoyed both.
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?

The movie version (2002) with Jim Caviezel was pretty good.
