For me, it's a tie between Takeshi Kaneshiro, who's already been mentioned, and Johnny Depp.
Both are talented and have the most gorgeous and interesting faces and expressions. Both have great hair and a great figure (although Kaneshiro's always been rather on the skinny side, he still looks amazing).
A few Kaneshiro pics, though only video does him justice I think.
Johnny Depp... Well, Johnny Depp is Johnny Depp, barely needs any evidence.
Ben Barnes, I think, is extremely beautiful. His smile in particular is dazzling.
Daniel Day-Lewis, in my opinion, used to be a real stunner.
A young British actor that I find both gorgeous and extremely talented is David Oakes (Pillars of the Earth, The Borgias...)
And I've seen some pictures of James Dean being posted, so I guess I'm allowed to go full "vintage" and post a pic of Jacques Dutronc when he was young. Of course I wasn't even born then but I still think of him as one of the most beautiful men ever.
And many more come to mind, but I think that will be enough for one post
