Jake Gyllenhaal gets down a gritty in "Nightcrawler," a film about a man who joins the rather unethical world of seedy freelance crime journalism in Los Angeles. After some strange teasers, a more straight forward full trailer has arrived and promises a gritty drama. It looks like a fun turn from Gyllenhaal, but even more appealing is the glimpses of Rene Russo back in what looks to be a juicy supporting role.
