Hollywood and Owain Glyndwr?
Promoting Wales in the USA
I love Ioan Gruffudd in anything at all and he's just bone Welsh -
http://www.imdb.com/name/nm0344435/ but I also think:Timothy Dalton
http://www.imdb.com/name/nm0001096/ Not racially Welsh but born in Wales and makes both a good king and a good sleazebag, old enough to do Glyndwr at the end of his life and very charismatically attractive;orChristian Bale
http://www.imdb.com/name/nm0000288/ Welsh and an incredible actor but maybe too young
