Oh. My. God. The comments from the last post about a possible Jamie have been delicious. Seriously.
I get what was said about the eyes not being cat-like enough... and him not being big enough (although that might be able to be remedied with lifting and body-building; depends on the actor's bone structure). One thing I will say is that Tracey is right; you really have to see someone moving around to get a feel for whether they'd be a good Jamie.
Unfortch - I have never seen anyone who has ALL of Jamie's qualities and I don't think we ever will. If they make a movie/series (yawn... getting tired of even talking about it because it seems as though it will never happen - and in some ways that is a good thing) they will have to compromise somewhere.
I think it comes down to this: What traits will you absolutely, positively NOT compromise on?
