“Look, it’s very, very simple,” says Cameron, “you read page 147 of the script and it says, ‘Jack gets off the board and gives his place to her so that she can survive.’ It’s that simple. You can do all the post-analysis you want. So you’re talking about the ‘MythBusters’ episode, right? Where they sort of pop the myth? OK, so let’s really play that out: you’re Jack, you’re in water that’s 28 degrees, your brain is starting to get hypothermia. ‘MythBusters’ asks you to now go take off your life vest, take hers off, swim underneath this thing, attach it in some way that it won’t just wash out two minutes later — which means you’re underwater tying this thing on in 28-degree water, and that’s going to take you five to ten minutes, so by the time you come back up you’re already dead. So that wouldn’t work. His best choice was to keep his upper body out of the water and hope to get pulled out by a boat or something before he died.”
