Few filmmakers are capable of capturing a time and place with the precision of Richard Linklater, and with his Toronto International Film Festival premiere of Blue Moon, he turns that gift toward the golden age of American musicals. The film unfolds in real time at Sardi’s on the historic 1943 opening night of Oklahoma!, where lyricist Lorenz Hart (Ethan Hawke) watches his longtime partner Richard Rodgers (Andrew Scott) celebrate a new creative chapter with Oscar Hammerstein. On the outskirts of the party, Hart masks heartbreak with quips and cocktails, confiding in a bartender (Bobby Cannavale), a young military composer, and Yale student Elizabeth Weiland (Margaret Qualley).
