Actor Kate Winslet says she and her "Titanic" co-star Leonardo DiCaprio "clicked immediately" when they met on the set of the blockbuster movie. The Oscar-winning actors played doomed lovers Jack and Rose in James Cameron's romance drama that went on to become one of the most successful movies in 1997.

In a behind-the-scenes featurette from the film's upcoming 4K Ultra HD DVD release, Winslet, 48, also reflected on her bond with Dicaprio. "Once I started working with Leo, we were able to kind of find our own rhythm," she said in a clip shared by Entertainment Tonight. "And it's amazing to kind of look back and think about it all over again," she said adding that they "clicked immediately, right away."
