Kate Winslet and Leonardo DiCaprio captivated audiences as star-crossed lovers in the 1997 epic romance " Titanic." That iconic scene where Jack and Kate meet at the bow of the ill-fated ship has earned a place in cinematic history, but haunted the movie's leading lady over the years.

"I can never get on a boat without someone saying to me, 'Oh would you mind? Can we just go on the front? Just for my mom. I literally offer it up now, whenever I got on a boat, I'm like, 'OK, Come on, form a line. Here we go,'" Winslet said today on " Good Morning America." "But it does happen and it will happen for the rest of the life I'm sure."

What moviegoers saw might have been magic -- Winslet flying on the boat's bow and exchanging a passionate kiss with DiCaprio surrounded by a spectacular sunset - but the filming was far less romantic and glamorous, Winslet revealed.

"I look back on it and all I remember it was always a rush. We shot it four or five times, if not more actually, just because [director] James Cameron wanted the option of various different lights in the sky. They're would always be this terrible rush, like, 'Oh my god, the sun is in the perfect spot. Come on, Kate, come on Leo, up onto the bow,'" she recalled. "To be honest to you, Leo and I were like, 'Oh my god, here we go again.' I'm not kidding you."

They finally got it right. The movie broke records, becoming the first to gross more than $1 billion at the box office. Timed to the 100th anniversary of the Titanic's sinking, the movie will hit the big screen again on April 4, but this time, in 3D.

"It does look spectacular I have to say…you sort of feel like you're on the fairground ride…as opposed to sitting back and watching the spectacle, you're really immersed in it," she said.

The movie solidified Winslet (and DiCaprio) as a force to be reckoned with in Hollywood. The powerhouse actress has become a regular on the awards circuit. The youngest actress to be nominated for six Academy Awards, she won the coveted Best Actress Oscar statuette for her role in 2009's "The Reader."

Winslet, who turned 21 while filming Titanic, is grateful that she became a megastar 15 years ago, before the onslaught of a 24-hour celebrity news culture, social media and paparazzi that push the bounds of privacy.

"I think now when young people are sort of thrust into the public eye like that, they're almost told they're successful and told they're famous before they even really know how to compute how that means, even before they can understand who they really are," she said. "I think there's a lot of pressure on young people to really be the thing that everyone is telling them that they are, opposed to discovering it for themselves."

Watch "Nightline" tonight at 11:35 p.m. ET and "Good Morning America" tomorrow for more with Kate Winslet.
