Tell some amazing facts about Movie Titanic ?

If you're a hardcore Titanic fan, you should know all of these by heart, just like every line from the movie. Are you ready to go back to Titanic?

Before DiCaprio, there was strong consideration for Cruise, Pitt, and even Sisto.

But thanks to 19-year-old Winslet's persistence, she was the only one who ended up with a winning ticket.

“I closed the script, wept floods of tears and said, ‘Right, I’ve absolutely got to be a part of this. No two ways about it,’” she told Rolling Stone in 1998. A few calls later, she was on the phone with Cameron, who was in his car.

You can thank Winslet for convincing her future BFF to say yes to Jack Dawson.

In the same 1998 Rolling Stone interview, Winslet revealed that she slipped out of a press junket to have a talk with him during the Cannes Film Festival. In 2016, DiCaprio shed some light on that conversation, telling Deadline, “We’d done all of these independent movies. I loved her as an actress and she said, ‘Let’s do this together, we can do this.’ We did it, and it became something that we could’ve never foreseen.”

Winslet flashed DiCaprio on one of their very first days of filming.

It wasn’t intentional, per se: “I was having my makeup put on – with nothing on – and there was Leo,” Winslet told PEOPLE in 1998. “He saw me and went, ‘Whooa!’ and I said, ‘We’re going to spend the whole day like this; we might as well get over it now.’ That broke the ice.”

DiCaprio was "like a cat” on set.

This, according to Cameron, who said DiCaprio “always made this big drama about getting wet.”

Eventually, he warmed up, quite literally, thanks to the crew members who poured buckets of warm water over the actor over months of filming. On the last day of filming, which took place underwater, Cameron lost sight of DiCaprio the cat. “I’m down there in my scuba equipment, and Leo comes down, and he’s a total fish underwater. And he’s [even] doing somersaults.”

DiCaprio would fart in his jacket on set and sweep it over Winslet's face.

“I mean, if anybody else in the world did that, they’d get slapped, and the other person would walk away and not talk to them for a week,” Cameron told Rolling Stone in 1998. “With Leo, Kate would just crack up.” Added Billy Zane in the same interview, “Grossing Kate out was purely Leo’s job. He was really good at it.”

Winslet and DiCaprio engaged in a lot of sex talk in between takes.

As the Rolling Stone profile revealed, the two would snuggle under a blanket in his trailer for these conversations.

“You know, some very, very personal things, asking each other for advice.

Not necessarily comparing notes but sort of, ‘No, don’t do it like that, do it like this.’ He’s very good at that. I have to say, a lot of those sexual tips he’s given me have worked. And I know it’s vice versa.”

Gloria Stuart was the only Titanic cast member who was alive during Titanic’s maiden voyage in 1912.

Stuart was almost 2 when the RMS Titanic perished in the Atlantic. In 1998, she also became the oldest Academy Award nominee at 87 when she was up for Best Supporting Actress. (Unfortunately, she lost to Kim Basinger, who won for L.A. Confidential.)

Rose stared at an incorrect star field in the film's original release.

Towards the end of the movie, a near-frozen Rose sees a sparkly night sky as Jack makes his way to the frozen afterlife. Unfortunately, that's not what a real Titanic survivor would have seen given the coordinates in the water, according to astrophysicist Neil deGrasse Tyson.

Ahead of the film’s 15-year re-release in 2012, Cameron adjusted it and revealed that Tyson sent him a “snarky e-mail” pointing out the error. “And with my reputation as a perfectionist, I should have known that and I should have put the right star field in," said Cameron. "So I said, ‘All right, send me the right stars for the exact time and I’ll put it in the movie.’”
