Jake Gyllenhaal showed signs of a significant weight loss when he got to work on the set of his newest film, Nightcrawler, in LA yesterday. The actor filmed a scene against a tree, where he gathered his long hair into a ponytail and creeped around a hill. The film follows a freelance reporter, played by Jake, who stumbles into the world of underground crime journalism.
Jake's sudden skinniness is surprising considering that just a month ago he looked like his normal self while promoting Prisoners. Of course, Jake is no stranger to gaining or losing weight, having bulked up for 2010's Prince of Persia: The Sands of Time.
