I think the Glyndwyr vs. Llywelyn question could be argued here ad nauseum, but the only real way to settle it is write scripts for both and see which becomes a blockbuster! :-D
I think Christian Bale ought to play Owain Glyndwr. He's a fabulous actor and you can definitely tell he's Welsh, from the cheekbones to the accent. (But then, I want him for the Richard III movie I'm writing too. *sigh*)
How funny that this came up here, when I had just recently started thinking about that myself while researching Owain Glyndwr for the "Wales and the Welsh" page of my website. His life would make such a cool movie.Hmm...
