Second of all: Good luck on quitting smoking. My wife has quit three times so far---once for two years!

Daniel Craig is the candidate du jour, but to me he just isn't quite physically right, and not just because he's only 5'9". To me, the bloke is simply too ugly, despite having a great screen presence. It's no more complicated than that.
