Film director Fisher Stevens, who worked with DiCaprio, 41, on the new documentary Before the Flood, opened up about the scary incident in a new interview with GQ magazine.
“I was filming [oceanographer] Sylvia [Earle] and I had this little easy camera to shoot underwater, and he was Sylvia’s diving buddy, so I said, ‘Would you film Sylvia?’ And he said, ‘Yeah, I love it, man, I love it,'” Stevens, 52, recalled.
“I was diving buddies with Edward Norton. So we go down and we see 300 Eagle Rays and Spotted Rays and it was an amazing dive,” he continued. “Leo bolts away with Sylvia, and Edward goes in front of me, and the next thing I know after 20 minutes, I’d lost them all. Then, I see Leo barely breathing, because Leo’s tank was leaking oxygen, and Edward had to save him!”
