Proving that actors keep some crazy hours, Jake Gyllenhaal showed up to film his new movie “Nightcrawler” late Monday evening (October 21).

The noticeably slimmer “Day After Tomorrow” hunk motioned for the shutterbugs to clear out as he geared up for yet another intense moment on camera, sporting a grey jacket and longer coif.

At the moment, Jake’s flick “Prisoners” is faring well at the box office, thanks in part to his on-screen chemistry with costar Hugh Jackman.

Of the “Les Miserables” lad, Gyllenhaal told GQ Australia, “I heard so many things about him, as we all have, that he’s such a good guy, such a nice bloke, but I had my own skepticism about that. But when I worked with him, the amazing thing about it, annoyingly so, is it’s just very true. He’s a good man. And as an actor, he’s so humble. I mean, given the position he’s in… People say success brings out who somebody really is, and he’s a deeply good man. He’s not performing it.”
