Losing Tons of Weight

Pay Cut

He Had Some Accident

In shooting one of the scenes for the movie, he hit a mirror - which was not in the original script. The actor said that it was kind of "in the moment" thing. Doctors stitched him up and wrapped his hands in gauze.

He Went to See "Carnage" Up Close and Personal

He's Really Passionate About The Movie

Jake Gyllenhaal is really passionate about the movie. He memorized the entire script even before they started. Gyllenhaal said that he is going to be real sad if the movie will come to an end. The actor said, "I would always be sad when we wrapped a scene because I'd think that's the last time I'm ever going to say the line, and it's so good. It deserves to be said again."
