James Cameron Says New 'Investigation' Will Finally 'Settle' Controversial 'Titanic' Door Debate

A new National Geographic documentary, 'Titanic: 25 Years Later,' puts the well-known theory to the test to finally get an answer.

James Cameron claims that Titanic fans will finally have a concrete answer after more than two decades to the question of whether or not Jack, played by Leonardo DiCaprio, could've survived with Rose, played by Kate Winslet, if he had joined her on top of the piece of debris.

For a new documentary, Titanic: 25 Years Later, National Geographic and Cameron did an in-depth experiment to test the long-held fan theory that Jack would've survived if Rose had just shared the door with him.

An already-released clip of the documentary shows two people dressed as Rose and Jack, reenacting everything the characters went through once they hit the water in the film.

Of course, the water isn't as cold as the night the Titanic sank, as it was 28°F then. For the experiment, they used 56°F water, but doubled the timing of everything because of this difference.

The clip only shows the experiment up to a point, saving the rest, as well as the results, for the release of the film.

Cameron spoke about the theory and experiment to a Television Critics Association panel last week, reported by USA Today, also clearing up the false assumption that what Rose lies on is a door.

He said, "A new investigation we've just done will settle this fan-based question about Jack and Rose and a piece of floating debris, which everyone calls a door."

The director continued, saying, "It's, technically, not a door. It's a piece of wood paneling from the first-class cabin."

Cameron further commented on the "forensic investigation," explaining, "Across four tests, we came to some pretty hard and fast conclusions." But you'll have to watch the documentary to find out how the investigation ended.

Titanic: 25 Years Later will be released on National Geographic on Feb. 5 at 9 p.m. EST.
