Well, I watch a lot of Billy Boyd interviews on the EE of LotR so I can do him pretty well. But I also like some of Michael Caine's films so I've seen some of those. But to answer your other question, we get some British films out here. Two comedies I can think of are Johnny English and Shaun of the Dead. But my favorite British comedy is Michael Caine and Ben Kingsley in "Without a Clue".
But we're getting off topic. Like I said I think it would be fun to play Caspian, Tirian, or any of the other ians. I was pretty excited to hear the rumour that they have started on the script for Prince Caspian and that they definitely plan to make it if the first film is a success.
