Danny DeVito Nearly Died During ‘It’s Always Sunny’ Stunt Mishap: ‘He Just Quietly Left’

The incident involved a stunt for a Season 11 episode, in which the show’s characters were trapped in a room with a water leak.

“It’s Always Sunny in Philadelphia” and its eccentric group of pub-owning characters have tickled fans for decades, but nearly cost actor Danny DeVito his life, according to a New York Post interview Tuesday with author Kimberly Potts.

While the incident hasn’t been a secret, Potts shared new details to promote her upcoming book, “It’s (Almost) Always Sunny in Philadelphia: How Three Friends Spent $200 to Create the Longest-Running Live-Action Sitcom in History and Help Build a Network.”

DeVito was filming an underwater scene for Season 11’s “The Gang Goes to Hell: Part Two” with co-stars Glenn Howerton, Kaitlin Olson, Charlie Day and Rob McElhenney, which required the star to be weighed down as the water level was raised.

“At one point, Danny got accidentally kicked, I think, in the shoulder — close to his head,” Potts told the Post. “As I’ve been told, he nearly drowned. It certainly had everyone afraid he was in trouble.”

She added, “He just quietly left, and the day was over for him. So even he has a threshold for how far he’s willing to go. But for the overwhelming majority, their experience with him is great. Kaitlin Olson has called him the happiest person she’s ever known.”
