Kate Winslet says that working on her forthcoming movie The Mountain Between Us was harder than working for her career-making role in Titanic. "This was much harder than Titanic because we really were at 10,000 feet and it really was -38 degrees Celsius. I definitely had Titanic flashbacks; freezing cold, falling into that cold water," says Winslet.

"It was definitely reminiscent of certain other rather challenging, strenuous experiences I had 20 years ago," she adds.

When asked whether she and her friend Leonardo DiCaprio would come together for a project any time soon, Winslet says no. "At the moment, no. There's nothing that Leo and I have planned. I would love to work with him again one day, but who knows? It might not happen until we're 70." she says.

The Mountain Between Us hits theatres on October 6, 2017.
