Ewan McGregor in the new Star Wars Prequels and Ed Norton in The Illusionist.
yosh mentioned that Ewan McGregor is British, and that he was trying to emulate the voice of Alec Guiness before he was a Sir.
I would like to mention that in all my years of seeing (and hearing) television, movies and radio from the British Isle, I have never heard an accent like that before.
It could very well be that I have never heard an actual English accent before.
I think it is a voice coach with his head stuck up his ass. My understanding is somewhat limited to what I have heard about the business, what I can guess from watching the product and to my own lifes experiences though.
