For Daniel Radcliffe’s upcoming film about Allen Ginsberg, the Harry Potter star is going to have some very good company. Variety reports that three promising young actors have joined the cast of the John Krokidas-directed Kill Your Darlings: Martha Marcy May Marlene break-out Elizabeth Olsen, Chronicle and In Treatment star Dane DeHaan (who was hotly pursued for Warner Bros’ big-budget Akira), and Boardwalk Empire scene-stealer Jack Huston. They’ll star alongside Radcliffe as a college-aged Ginsberg, who finds himself drawn to the magnetic Lucien Carr (DeHaan), Jack Kerouac (Huston), and Kerouac’s girlfriend Edie Parker (Olsen), though their relationships take a dark turn when Carr commits a murder. Yeah, that’s usually a dealbreaker.
