Kiwi director Bart Layton: bizarre story behind American Animals

British-Kiwi filmmaker Bart Layton's film American Animals opens in cinemas on October 25. It's based on the true story of a 2004 heist by four college students - who plotted to steal rare books from Transylvania University - among them a copy of Charles Darwin's Origin of Species and John James Audubon's huge tome Birds of America. What makes the film different is that while the film is fictionalised, the real protagonists appear in the film, documentary style. Bart Layton talks about how he came across the story.
