That floating door could not have held two people, James Cameron says.

The Oscar-winning director of Titanic was asked in a recent interview with The Daily Beast about the long-running dispute over the ending of his 1997 blockbuster hit, when a piece of wood debris from the title ship keeps Rose (Kate Winslet) out of the freezing water while her lover Jack (Leonardo DiCaprio) perishes. C’mon, there had to room for both of them on there, right? After all, didn’t Discovery Channel’s Mythbusters prove they could both have survived using their lifejackets tied to the door for added buoyancy?

“OK, so let’s really play that out,” Cameron said. “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 5-to-10 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.”

Cameron added about the Mythbusters series: “They’re fun guys and I loved doing that show with them, but they’re full of sh–.”

Back in 2012, the Mythbusters team presented Cameron with the results from their tests. “I think you guys are missing the point here,” Cameron said at the time. “The script says Jack dies, he has to die. Maybe we screwed up. The board should have been a tiny bit smaller. But the dude’s going down.”

Cameron didn’t only talk about Titanic in this new interview; he also says we’re probably doomed, too. The director was asked about whether he was concerned that Donald Trump would wreck the environment now that he’s president.
