I loved Margie in the number when I saw it at the Kenn Center. Partially because the actress playing her did a fantastic job. But at least we got to see her later in 'Buddy's Blues.'
Mine:
The moment in 'Coast of Utopia's' 'Shipwreck' where the overlapping dialogue at the party shifts to just Vissarion saying how tired he is of utopias, and speaking of the hope in seeing the progress of the train tracks in his country. In just that one small scene, Crudup captured what it took 3 more hours and a huge number of actors to keep conveying. His performance was masterful, and so was the writing in that scene.
Also I'm going to say Liev Schriber near upstaging everyone in the 'View from the Bridge' revival, just seething with this physical lust in the background in every scene. Even thought the rest of the cast turned in fine performances, he just drew in power in every moment he was up there, even without speaking a word.
