In its review of Blue Moon,The Guardian calls Richard Linklater’s latest film a “bitter Broadway breakup drama.” But it’s not the kind of breakup we’re used to—it’s about work not love. The split in question is between the lyricist Lorenz Hart and the composer Richard Rodgers, the songwriting duo behind such classics as My Funny Valentine (1937), The Lady is a Tramp (1937), and, as the title suggests, Blue Moon (1934). By the early 1940s, Hart had become unreliable, disappearing on drinking binges for days at a time. Rodgers moved on. Their split is the subject of Linklater’s film, set around the 1943 premiere of Oklahoma!, the first musical Rodgers (Andrew Scott) wrote with his new partner, Oscar Hammerstein II. The focus, though, is on the despairing Hart (Ethan Hawke), his drinking, his sexuality, and his love for the young university student Elizabeth Weiland, played by Margaret Qualley. —Jeanne Malle
