Jake Gyllenhaal was hospitalized after punching a mirror on the L.A. set of his new film Nightcrawler on Wednesday morning, reports indicate.
Stating the obvious, "Jake flipped out," a Nightcrawler set source says.
"His character was looking into a mirror during the scene and he punched the mirror in anger and broke it, cutting himself so bad he had to be taken to a hospital."
A source close to Gyllenhaal, 32, confirms the actor received stitches in the emergency room, but says it was nothing more than a moment in character.
Not comparing actors to soldiers, but Jake does work 18-hour days.
