Leonardo DiCaprio got down on his knees for Kate Winslet in a pivotal “Titanic” scene. Winslet, 48, discussed the Oscar-winning 1997 film at an advanced screening for her new movie “Lee” at the 92nd Street Y in New York City on Monday, Sept. 23.

During a Q&A, Winslet spilled some tea about the movie’s infamous and much-debated door scene, according to People . Winslet wagered a guess that co-star DiCaprio has “got PTSD” from being asked incessantly about the scene, in which – spoiler alert – he freezes to death because there’s not enough room for him on a floating door that Winslet’s character, Rose, has taken refuge on after the Titanic’s sinking. “Well that was quite an awkward tank,” Winslet said of the giant water tank used to film the scene.

“Because to burst the bubble, it was waist height at that time.” “Leo, I’m afraid to say, was kneeling down. I shouldn’t be saying – anyways, Jimmy Cameron’s gonna be ringing me,” the actress quipped, referring to the movie’s director James Cameron .

Though the tank’s schematics proved less than ideal for DiCaprio, Winslet had one major benefit: she could easily pop off to the restroom. “So first of all, I was regularly like, ‘Can I just go for a pee?’ And then I get up, get off the door, walk to the edge of the tank, sort of 20 feet away and I literally have to fling my leg over and climb up and come and get back on the door again,” she recalled. “It’s terrible.
