'GLOW' star Betty Gilpin was accidentally forgotten in a body bag while playing a corpse on 'Law & Order'

• Actress Betty Gilpin told Jimmy Fallon she was once left in a body bag on the set of "Law & Order."
• The "GLOW" star said the incident happened on her first acting job.

Actress Betty Gilpin said she was accidentally left in a body bag on the set of "Law & Order" in an appearance on "The Tonight Show Starring Jimmy Fallon" on Friday.

While working on "Law & Order: Criminal Intent" in 2006, Gilpin was playing a woman who was found dead in an oil drum. The "GLOW" star told Fallon that after she was filmed inside a body bag and zipped up, the production crew wrapped for lunch, leaving her inside.

"And I hear, like, footsteps on gravel getting farther and farther away, van doors closing," she said. "And then, like, 10 seconds goes by. I hear one far-away [production assistant] being like, 'Oh my God,' and footsteps coming towards me. Unzips, sunlight on my face, yeah."

She joked that she didn't call out for help because it was her first job and she didn't want to appear "high-maintenance." Gilpin also noted that she played the daughter of actress Fran Drescher's character for the episode.

According to IMDb, Gilpin appeared on "Law & Order" shows three more times in her career. Fallon said working on "Law & Order" was considered a rite of passage for New York actors like Gilpin, who was born and raised in the city.

Representatives for Gilpin and NBC did not immediately respond to Insider's request for comment.
