Betty Gilpin was no stranger to the show in her early years, appearing on both the flagship “Law and Order” show and many of its spinoffs. Appearing on “The Tonight Show Starring Jimmy Fallon” this week, the “GLOW” star opened up about the multitude of roles she played on “Law and Order,” including “a pedophile with vocal fry” and “a lesbian with acne.” But her most memorable experience on the show happened during what should have been her easiest role: playing a corpse. “I was found naked in an oil drum — Vincent D’Onofrio found my naked, dead body,” Gilpin said, before adding that she was almost abandoned in a body bag. “I just had to sort of be in there. They called cut, like, ‘That’s lunch, guys! Great day! I hear footsteps on gravel getting further and further away, van doors closing… 10 seconds goes by, I hear one far-away PA being like, ‘Oh my God,’ and footsteps coming towards me.” It’s fortunate that the PA remembered she was there and came back for her, because otherwise Gilpin may have never been found. The actress joked that her fear of seeming difficult on set kept her from calling for help. “I didn’t want to be high maintenance,” she said. “I wanted to work again.”
