The 28-year-old actor said he sparked an emergency when he dived into a pool of water with the famous mask over his face, reported New York Daily post.
"I had to get wet, and I just kind of dove in and didn't realise that water on the mask made it impossible to breathe. So I was kind of, like, suffocating. I couldn't get any oxygen! I water-boarded myself," he said.
The film will be hitting theatres on July 3.
