On the latest episode of the Talkhouse Film podcast, in a special conversation recorded after a screening of Laurie Anderson's documentary Heart of a Dog, the acclaimed musician, artist and filmmaker talks onstage with fellow New York director Darren Aronofsky, best known for his films Pi, Requiem for a Dream and Black Swan. The pair discuss Anderson's new film, which ponders questions of love, death and language, and touch on such other diverse subjects as Herman Melville's discussions with his editor about Moby Dick and the problems that can come from putting batteries in one's mouth.
