I love the classic A Man For All Seasons. The wit of St (Sir) Thomas More is well portrayed by Paul Scofield. For example:
Sir Thomas: No, my lord, you don't. You may suppose I have objections, all you know is that I will not swear to it, for which you cannot, lawfully, harm me further. But if you were right in supposing me to have objections, and right again in supposing my objections to be treasonable, the law would let you to cut my head off.
Duke of Norfolk: Oh... yes...
Cromwell: Oh well done, Sir Thomas. I've been trying to make that clear to his grace for some time.--The Baron
