He looks like Andy Hallett
Andy Hallett, http://www.imdb.com/name/nm0356468/, best known as his role as Lorne, The Host on 'Angel'
I just happened to tune into Charlie Rose, (http://www.imdb.com/title/tt0270116/), and he was interviewing the Coen brothers. The two of them were on the screen. I did not know what they were discussing. Suddenly the camera panned to Richard Kind, (http://www.imdb.com/name/nm0454236/), and another person. I thought to myself, oh my g-d, is that Andy? When the heck was this interview done? And what are they talking about? Well, the fourth person is in fact not Andy Hallett, it is of course Michael Stuhlbarg, and the four of them were (are) being interviewed by Rose about 'A Serious Man', (http://www.imdb.com/title/tt1019452/). But looking at Stuhlbarg made me do a double take. I also think he looks a bit like Joaquin Phoenix, (http://www.imdb.com/name/nm0001618/), sans the beard. I see someone else on this board also mentioned that they think Stuhlbarg looks like Phoenix as well.
