Sleeping with Charlie Kaufman is a 2010 American short animated comedy film created by J Roland Kelly using Xtranormal.
In an interview with Xtranormal, J Roland Kelly describes the film as ...basically this absurd, funny conversation between a guy and his girlfriend. He tells her he fantasizes about her twin sister, but she doesnt have a twin sister, so its just another way of fantasizing about her and is she offended. It draws on some La Nouvelle Vague amp Mumblecore elements from the kind of films I was watching at the time.
