Winslet and DiCaprio have been friends since the 1997 premiere of the highest grossing film of the year -- such good friends that they still recite movie lines to each other.
"You don't even want to know the last conversation we had because it was so funny and made me laugh so much," Winslet told Glamour U.K. "We found ourselves saying to each other, 'Can you imagine if the world really knew the stupid things we say?' I'm not going to tell you what we actually talk about, but yeah, we're very, very close, and sometimes we do quote the odd 'Titanic' line back and forth to each other because only we can, and we find it really funny."
When asked about not having a plan B if acting didn't work out, Winslet admitted she "should have had one."
"If it had all gone tits up, I would have been stuck," she said. "I had a fleeting idea about becoming a hairdresser, but I cut off a friend's earlobe trying to cut their hair. I saw him again not too long ago and I was like, 'I'm so sorry for your earlobe.' He said, 'Yeah, you can still see the marks, but I'm proud of that now, Kate!"
Those familiar with "Titanic" are aware Winslet has a knack for surviving disasters, but anyone who's seen "The Wire" can't say the same for Idris Elba, who stars alongside Winslet in "The Mountain Between Us."
The suspensful action-drama, which hits theaters Oct. 20, follows a journalist (Winslet) and doctor (Elba) who decide to take a small private plane to get home when their commercial flight plans fall through.
Turns out, they made the wrong decision, and they wake up in the wreckage of the small plane high up in the snowy mountains where they can either wait for help or make the trek down by themselves.
