Titanic is a 1997 American epic romantic disaster film directed, written, co-produced, co-edited and partly financed by James Cameron. A fictionalized account of the sinking of the RMS Titanic, it stars Leonardo DiCaprio and Kate Winslet as members of different social classes who fall in love aboard the ship during its ill-fated maiden voyage.

Upon its release on December 19, 1997, the film achieved critical and commercial success. Nominated for fourteen Academy Awards, it won eleven, including the awards for Best Picture and Best Director, tying Ben Hur (1959) for most Oscars won by a single film. With an initial worldwide gross of over $1.84 billion, it was the first film to reach the billion-dollar mark. It remained the highest-grossing film of all time, until Cameron's 2009 film Avatar surpassed its gross in 2010. A 3D version of the film, released on April 4, 2012 to commemorate the centennial of the sinking, earned it an additional $343.6 million worldwide, pushing its worldwide total to $2.18 billion. It became the second film to gross more than $2 billion worldwide.
