Yes, he was. Have you ever seen
A Man For All Seasons? It was an excellent movie about Saint/Sir Thomas Moore. (It was made when Hollywood actually made beautiful movies.) If you haven't seen it, try to rent it. I think you would like it a lot.
As for Henry, ugh, the only good thing that man did was sire Elizabeth the First. Now she was a remarkable woman. :O)
It's a very good play by Robert Bolt and an excellent movie. It plays fast and loose with some historical facts, but history doesn't always make a good two-hour movie.
Orson Welles was over the top, but what else is new? < g >
