Hi,
Thank you, Ilyala, for that portrait of John of Gaunt. He looks a little like Vlad the Impaler to me - handsome but a little dangerous!!
And you're right, Charlton Heston he's not....
I'll go out on a limb here and suggest Hugh Jackman or Gerard Butler.
There is a British actor called Nathaniel Parker, who resembles JG; but I think he's too old now for the role.
