Kate Winslet reveals 'door' in Titanic wasn't a door

Kate Winslet has revealed the “door” in the much-debated Titanic scene wasn’t in fact a door.

The 49-year-old actress played Rose alongside Leonardo DiCaprio as Jack in James Cameron’s 1997 blockbuster film about the doomed Titanic liner.

The film controversially ended with the young lovers stranded in the icy waters of the North Atlantic Ocean as the Titanic sinks to the murky depths.

Winslet’s character survives by sitting on what appears to be a floating door, while Jack clings to its side before freezing to death to apparently avoid adding his weight to the wood and causing it to sink.

Winslet was recently asked on the Australian talk show The Project if there was “room on the door” that would have saved Jack’s life.

“What I will say that’s really interesting is people keep referring to it as a door. It actually wasn’t even a door,” she said.

“It’s a piece of bannister, like stairway or something, that had broken off.

“Who knows if (Jack) could’ve (fitted) on there or not.

“Honestly, I don’t have any insights here that anyone else hasn’t already tried to figure out.”

Armies of Titanic fans are still outraged Rose didn’t let Jack share space on the “door” and still run online forums discussing the scene.

Titanic director James Cameron, 70, is said to have commissioned a scientific study to determine if there was enough room for both Jack and Rose, with the director and a team of scientists apparently using two stunt doubles to re-enact four different scenarios.

“Jack might’ve lived, but there’s a lot of variables. I think his thought process was, ‘I’m not gonna do one thing that jeopardises her’,” he said last year.

Winslet says her co-star DiCaprio has probably developed “PTSD” from being asked so many times about the door scene.
