Titanic is a 1997 disaster film directed, written, co-produced and co-edited by James Cameron about the sinking of the RMS Titanic. It features Leonardo DiCaprio as Jack Dawson, and Kate Winslet as Rose DeWitt Bukater, two members of different social classes who fall in love aboard the ill-fated 1912 maiden voyage of the ship. The main characters and the central love story are fictional, but some supporting characters (such as members of the ship's crew) are based on real historical figures. Gloria Stuart plays the elderly Rose, who narrates the film in a modern day framing device.

Production of the film began in 1995, when Cameron shot footage of the real wreck of the RMS Titanic. He envisioned the love story as a means to engage the audience with the real-life tragedy. Shooting took place at the Akademik Mstislav Keldysh for the modern scenes, and a reconstruction of the ship was built at Playas de Rosarito, Baja California. Cameron also used scale models and computer-generated imagery to recreate the sinking of the ship. Titanic became at the time the most expensive film ever made, costing approximately US$200 million with funding from Paramount Pictures and 20th Century Fox.
