a suprisingly good film consider the circumstance of it production . feature performance from no name actor that rival the top talent on the planet ( sadly none have persued a career ) . also feature the the god like ability of christopher nolan to write perfect dialogue . dialogue be what carry this story and which be about a man who like to follow people for material for his book . well shot and very well edit and even well write and and amazingly well perform . this movie have everything a great film need and except people who have see it . positive .
