I wouldn’t consider myself a Jake Gyllenhaal fan but I think there might be something here in his latest upcoming film Nightcrawler (no, not that one). Strapped for cash and a little bit desperate, the guy gets into filming crimes. But the indication is that he takes it a little too far and hides evidence and covers things up when it helps him get a better story. In short, he because obsessed with the work in a very not good way.
