Jake Gyllenhaal was sent to the emergency room with an injured hand Wednesday morning after punching a mirror on set, People reports. While filming an intense scene on Nightcrawler‘s Los Angeles set, the 32-year-old actor wounded his hand so badly that he had to be taken to a nearby hospital, a source told the magazine.

“The scene was emotionally charged and his character was talking into a mirror and he got so into it, he banged his hands against the mirror and it broke and cut him,” the source said. “It was all the scene and not because he was mad about anything else.”

Gyllenhaal returned to set Thursday.
