The upcoming movie Kill Your Darlings will look at the relationship between beat authors Allen Ginsberg and Jack Kerouac, and the man who introduced them, Lucien Carr. It was a relationship that reportedly began with murder, as soon after the three became friends Carr was implicated in the killing of another man named David Kammerer, and the famous authors found themselves caught in the middle of all the drama. Sounds like a saucy little story, especially with the “based on true events” factor that it has working for it. But perhaps even more exciting than the murder aspects of this story is the cast that it is now being assembled to bring it to life. The first casting announcement was that Daniel Radcliffe would be shrugging off his wizarding robe and branching out in another direction to portray Ginsberg. The idea of watching Radcliffe do something so different could have been enough to sell people on this movie alone, but some new casting details have surfaced that add to the anticipation. According to a report from Variety, not only has the Kerouac role been filled by Boardwalk Empire’s Jack Huston, and the Carr role filled by In Treatment’s Dane DeHaan, but Martha Marcy May Marlene’s breakout star Elizabeth Olsen has signed on as well. She’ll be playing Edie Parker, who was an art student and a girlfriend of Kerouac’s.
