Jake Gyllenhaal – Nightcrawler
In his latest film Nightcrawler, Gyllenhaal’s high-strung character vents his frustration on his bathroom mirror. [Gyllenhaal was hospitalized after, as he put it, “A mirror broke in the middle of a scene that I was shooting. I hit a mirror and it broke and it cut my hand.” That description is rather low-key, but Gyllenhaal, despite being pretty badly injured, stayed in character while the camera was rolling. If you pay attention, you can catch Gyllenhaal hiding his injured hand behind his back during other scenes in the movie.
