Careful, therein lies the trap of hi-res imagery: Scrutinizing every detail. (Try looking for some of the ones we've posted in the past where he's at an event and not wearing makeup for on-camera. He's got better skin than most men I know... hell, most *women* I know, for that matter ;) )
Didn't someone say a while back that he was looking like Robert Redford?
Ha! That was me. He frequently reminds me of Redford (one of my faves) in a variety of ways. And actually, Jamie's got better bone structure so he probably won't get as craggy as Redford when he's in his 60's or later.
(LOVE Barefoot in the Park - and though Bob's terribly handsome in that (at 31), I'd probably argue that he's hotter in All the President's Men (40)... although, see previous comment. ;) )
