We were absolutely obsessed with Titanic (who wasn’t?). Some of us even had the catalog — yes there was a catalog, full of Titanic memorabilia like jewelry and blue prints of the famed sunken ship. Not naming names.

Director James Cameron knows how much we love Titanic, and one of the biggest debates fans have been having for nearly two decades is the likelihood of Jack Dawson surviving had he been able to float on the door, which ended up saving Rose’s life.

Was there room for Jack on the door?

“Look, it’s very, very simple,” James said to the Daily Beast. “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. 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.”

James even humored the idea of an episode of Mythbusters, which sought out to determine whether both Jack and Rose could have fit on the floating door.

“OK, so let’s really play that out,” he explains. “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. They’re fun guys and I loved doing that show with them, but they’re full of s***.”
