This is a play! One by Bruce Norris. Not typical of this list, I grant you. It's just that it is the best play I've seen in years; it won the Tony and, before that, a Pulitzer, so I'm not saying anything original. It takes place in two different time periods, 1959 and 2009, and all the lead actors — Christina Kirk, Jeremy Shamos, Frank Wood, Damon Gupton, Annie Parisse (Sarah Goldberg took over for her in this part), Crystal A. Dickinson, and Brendan Griffin — played two roles. They're all leads, really, and the Tony Awards had so much trouble figuring out how to reward their shared amazingness that the voters nominated only Shamos (who lost). My complimenting them as a collective here will surely make up for that slight, right? —K.A.
