Titanic is a 1997 American epic romantic disaster film directed, written, produced, and co-edited by James Cameron. Incorporating both historical and fictionalized aspects, it is based on accounts of the sinking of RMS Titanic in 1912. Leonardo DiCaprio and Kate Winslet star as members of different social classes who fall in love during the ship's maiden voyage. The film also features an ensemble cast of Billy Zane, Kathy Bates, Frances Fisher, Gloria Stuart, Bernard Hill, Jonathan Hyde, Victor Garber, David Warner, Suzy Amis and Bill Paxton.

Epic films have large scale, sweeping scope, and spectacle. The term is slightly ambiguous, sometimes designating a film genre and at other times simply big-budget films. Like epics in the classical literary sense, it is often focused on a heroic character. An epic's ambitious nature helps to set it apart from other genres such as the period piece or adventure film.
