Ethan Hawke plays Hart; the setting, for the most part, is Sardi’s, the Broadway hangout where directors and actors would gather, post-performance on opening night, to wait for the reviews to roll in. Hart isn’t supposed to be drinking; he’s been trying to get off the sauce. But bars are convivial places, and right now Hart needs that connection. He greets the bartender, Bobby Cannavale’s Eddie, like a long-lost brother. The two trade quips from Casablanca. He wheedles one drink from his friend—followed by another, and another. He tells Eddie about a college girl he’s madly in love with; her name is Elizabeth, and he’s waiting for her to join him at the bar. Because later that evening—it’s March 31, 1943—Hart’s former songwriting partner Richard Rodgers (Andrew Scott) will show up with his new librettist and lyricist, Oscar Hammerstein (Simon Delaney). Their new musical, Oklahoma!, has just opened. From the audience, Hart watched as much of the show as he could before decamping to the bar. As he describes the debacle he’s just witnessed, his body language is one giant eye roll. “Oklahoma, with an exclamation point, no less,” he says drily.
