Titanic was one of three films to win a total of 11 Academy Awards, the
others being Ben- Hur and The Lord of the Rings: The Return of the King.
The studios wanted Matthew Mcconaughey but James Cameron insisted on Leonardo Dicaprio.
For some wreck interior shots, a set was constructed and submerged.
At $ 200 million, the movie cost more than the Titanic itself. The cost to construct the ship in 1910- 1912 was £ 1.5 million, equivalent to $ 7.5 million at the time and about $ 120-$ 150 million in 1997 dollars.
The film was No. 1 at the US box office for a record 15 consecutive weeks, from December 19, 1997, to April 2, 1998.
Most of the decor on the ship was reconstructed by or under the supervision of researchers of the White Star Line, the original company that constructed and furnished the Titanic.
It was the highest grossing film in box office history, with worldwide takings of US$ 1.8 billion until it was surpassed by Avatar. Both films were directed by James Cameron.
The film contains more than 100 speaking parts and more than 1000 extras, all of whom needed to be dressed in lavish period costume.
Both Kate Winslet and Leonardo Dicaprio learned how to dance the polka for the scenes set at the party in the third- class compartments.
Before announcing development of this film, James Cameron shot footage of icebergs off the coast of Nova Scotia under the pretence of making a film titled Planet Ice.
