Winslet sails again as Titanic gains a new dimension Kate Winslet signed autographs as she walked the red carpet at the re-launch of the film that made her a star. She was joined by co-star Billy Zane and director James Cameron at the Royal Albert Hall in Kensington, west London, for the premiere of 'Titanic 3D'. Winslet played sensitive socialite Rose DeWitt Bukater alongside Leonardo DiCaprio's Jack Dawson in the epic drama. The couple's doomed love affair on board the ill-fated boat has been converted into 3D 15 years after the release of the original 'Titanic', which became a box-office smash and and went on to win 11 Oscars. Cameron said: "The 3D enriches all of Titanic's most thrilling moments and its most emotional moments. More than ever, you feel you're right there going through all the jeopardy that Jack and Rose go through. The 3D kicks the whole experience up to another level.
