In the upcoming thriller Nightcrawler, Jake Gyllenhaal stars as a go-getter who gets a lot more than he bargained for when he scratches his way into the seedy, underground world of freelance crime journalism. In what may be the greatest (and craziest) role of his career, Gyllenhaal plays an unemployed self-motivator who discovers a lucrative career in videotaping crime scenes and selling the footage to local news stations. Ridiculously compelling and stuffed with memorable edge-of-your-seat moments, Nightcrawler is one of the most buzzed-about movies of the fall season. The film, which critics are already calling a "modern masterpiece," hits theaters on October 31.
