Trivia Monday!

Our trivia question last week was "What famous Brit said 'Necessity is the plea of every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves.'?" I confess I gave you a little bit of a clue and a misdirect with the picture that accompanied the question, because while it was a still from the movie Amazing Grace, it did not feature the speaker.
 Caroline correctly guessed that it was William Pitt, who was also represented in the  film by one of my favorite actors, Benedict Cumberbatch. The real William Pitt the Younger was, at that time, the youngest Prime Minister to take up the office, at the age of 24.

So onto this week's trivia:- What Enlightenment Monarch has been portrayed by both Danny Huston and Jeffrey Jones, though in very different ways; and apparently requested upon his death that his epitaph should read "Here lies _, who failed in all he undertook."?
