Who plays opposite Kate Winslet in the 1997 film 'Titanic'?

Explanation

Leonardo DiCaprio (born 1974) rose to fame after his lead role in 'Titanic' (1997) where he played Jack Dawson opposite Kate Winslet in the role as Rose DeWitt Bukater. 'Titanic' was a very expensive film to produce and was the first to have a budget over $200 million - more than it cost to build the Titanic in the first place. In 1910, the ship cost £1.5 million to build, which amounts to some $120 to $150 million in 1997-dollars.
