Leonardo DiCaprio

‘The Killers of the Flower Moon’ actor was rescued by Edward Norton, 54, during a 2016 scuba diving session with marine biologist Sylvia Earle in the Galapagos Islands.

Leo's oxygen tank failed as he was observing rays and Norton swam to him so they could practice "buddy breathing".

DiCaprio - who was filming climate change documentary 'Before The Flood' - told WIRED magazine: "If a cat has nine lives, I think I've used a few.”
