The first teaser trailer for Daniel Radcliffe's "Kill Your Darlings," in which he plays former Columbia student and pretty important poet Allen Ginsberg, is out now. The former "Harry Potter" drew gigantic crowds when the film was shot on campus in April 2012. Marvel in the beauty of Low and Butler, and also some classroom (Fayerweather? anybody know?), and imagine that Maggie Smith is about to walk out with the Sorting Hat.
