In what is shaping up to be an interesting cast full of young up-and-comers, Kill Your Darlings has now claimed Elizabeth Olsen (Martha Marcy May Marlene) among its ranks. Alongside Daniel Radcliffe (Harry Potter), Dane DeHaan (In Treatment) and Jack Huston (The Twilight Saga: Eclipse), Olsen is set to play Edie Parker, the well-to-do, art-student girlfriend of Jack Kerouac (Huston). The thriller centers around a murder at Columbia University in 1944 that served as a formative experience for the young writers who would catalyze the Beat Revolution. Radcliffe will play Allen Ginsberg who befriends classmate Lucien Carr (DeHaan), whose murder of David Kammerer will be central to the story. When we first reported on this project,  Chris Evans (Captain America), Jessie Eisenberg (The Social Network) and Ben Whishaw (Perfume: The Story of a Murderer) were cast as Kerouac, Ginsberg and Carr, respectively. I think this current lineup has a much better feel to it (although I’m unfamiliar with Whishaw). Hit the jump for more on Kill Your Darlings.News of the casting of director John Krokidas’ Kill Your Darlings comes via Showblitz. Radcliffe was assumed to have the role of Ginsberg months ago, though the rest of the casting is new. While some people may know her as the younger sister of the Olsen twins, Olsen turned heads at last year’s Sundance with Martha Marcy May Marlene. She can next be seen in the horror flick, Silent House, opening March 9th. DeHaan is another unfamiliar name to many, but may gain some notoriety as a teenager who acquires superpowers in the Josh Trank picture, Chronicle, which opens February 3rd. Radcliffe, on the other hand, is known internationally as Harry Potter, though he can next been seen in the gothic horror flick, The Woman in Black, which also debuts on February 3rd. Lensing for Kill Your Darlings is scheduled to begin on March 12th at Columbia University in New York.
