Kate Winslet Breaks Movie Record For Holding Breath Underwater

No scuba gear, no problem.

Kate Winslet held her breath underwater in a scene for “Avatar 2” that put stunt enthusiast Tom Cruise to shame.

“It was brilliant and I was very proud of myself and I’ll probably never be able to do it again,” Winslet told “ET” on Tuesday. “That came at the end of four weeks worth of quite intense training and it was in the dive tank, it was in the training tank. But I loved it.”

“Avatar” producer Jon Laundau previously posted a photo of Winslet at work in the depths.

Winslet has been mostly tight-lipped about her role in James Cameron’s sequel to his massive 2009 sci-fi blockbuster. She did allow in an August interview with The Hollywood Reporter that she is “a water person.”
