Still thinking of England...

OK, so Simon Baker's an Aussie?
He still counts as a guy from and English-speaking country that's not America playing an American on TV.
And I left out Julian Ovenden, who played adorable Andrew Foyle on Foyle's War. I hear he's on "Cashmere Mafia." A show I would never watch under any circumstances, so I don't know if he's playing an American or not.
