Kate Winslet thought she literally spent seven minutes in heaven after holding her breath underwater for a record-breaking amount of time.

The “Avatar: The Way of Water” star revealed that she assumed she was “dead” after coming up for air at the seven-minute, 15-second mark. Winslet broke the record previously held by Tom Cruise.

“I have the video of me surfacing saying, ‘Am I dead, have I died?’ And then going, ‘What was [my time]?'” Winslet told Total Film magazine (via Games Radar). “Straight away I wanted to know my time. And I couldn’t believe it…The next thing I say is, ‘We need to radio set.’ I wanted Jim to know right away.”

Director James Cameron quipped, “She’s not competitive at all.”

“Titantic” alum Winslet continued, “Well, I didn’t have to hold my breath for over seven minutes. It’s just that the opportunity to set a record presented itself.
