Mariska Hargitay tells People that she has fully recovered from the partially collapsed lung that first sidelined her from filming NBC’s Law & Order: SVU last January, and again in March. She also revealed the origin of the injury: “I’ve been doing my own stunts on the show for 10 years,” the 45-year-old actress explained. “I fell wrong, basically. I collapsed my lung doing a stunt.”
