Ethan Hawke planned to play real-life songwriter Lorenz Hart for more than a decade. While ethanhawke and Richard Linklater were making “Boyhood,” the filmmaker sent Hawke a piece of writing about the opening night of the Broadway musical “Oklahoma!” that recounted the evening from Hart’s point of view as his former creative partner Richard Rodgers created a hit with Oscar Hammerstein. “It struck me as one of the most brilliant ideas I’d ever heard, of what it would be like to be Lorenz Hart at that opening night party,” Hawke recalls. “It’s all of humanity inside this little evening.” Over the next few years, Linklater, Hawke and Robert Kaplow, the author of the original piece, worked together to build what became #BlueMoon, an intimate, evocative film that takes place just months before Hart’s death.
