Kate Winslet has sweary response to Titanic fans saying Jack could have fit on the door

One of cinema's most heartbreaking scenes is unquestionably the moment Jack Dawson slips below the waves of the North Atlantic in Titanic.

It's sparked many a debate over the years about whether or not Leonardo DiCaprio's character could have fit on the door from the Titanic, and now Kate Winslet has finally weighed in with a very sweary response.

The actress, now 47, who famously played Rose Dawson in the hit 1997 film, made the revelation as part of an appearance on the Josh Horowitz podcast Happy Sad Confused.

Horowitz began by referring to the controversy around the door before asking Winslet if she thought Jack could fit on it too - giving Titanic fans the happy ending many longed for.

"I don't f**king know. No, that's the answer is that I don't f**king know," Winslet said, laughing.

She then paused before giving her serious thoughts on one of cinema's biggest debates.

"All I can tell you is I do have a decent understanding of water and how it behaves, I really do," she said. "If you put two adults on a stand-up paddleboard, it becomes immediately extremely unstable, that is for sure.

"I actually don't believe that we would have survived if we had both gotten on that door.

"I think that he could have fit, but it would have tipped and it would not have been a sustainable idea."

She then pointed out that critics said she was too fat at the time of her appearance in the film for Jack to have survived.

"And also, apparently, I was too fat," she joked.

"Isn't it awful? Why were they so mean to me? They were so mean. I wasn't even f**king fat."

The actress then rounded off her response by concluding: "You've heard it here, for the first time, yes he could have fit, he could have fit on that door, but it would not have stayed afloat. It wouldn't."

Winslet's assertion was backed up by Titanic director James Cameron, who said he conducted experiments to see if it was possible to save Jack.

He told The Toronto Sun that he did it so he wouldn't 'have to deal with the speculation anymore after 25 years.'

"We have done a scientific study to put this whole thing to rest and drive a stake through its heart once and for all," he admitted.

"We have since done a thorough forensic analysis with a hypothermia expert who reproduced the raft from the movie and we’re going to do a little special on it that comes out in February."

The Titanic director continued: "We took two stunt people who were the same body mass of Kate and Leo and we put sensors all over them and inside them and we put them in ice water and we tested to see whether they could have survived through a variety of methods and the answer was, there was no way they both could have survived. Only one could survive."

"[Jack] needed to die. It's like Romeo and Juliet. It's a movie about love and sacrifice and mortality. The love is measured by the sacrifice…Maybe after 25 years, I won't have to deal with this anymore."
