Video (HD 1080p)
1) Shown in video above - CGI crowd in first scene, CGI water from 0:41, CGI vapor from actors mouth at the end.
2) It remained the highest-grossing film of all time until Cameron's Avatar surpassed it in 2010.
3) The climactic scene, which features the breakup of the ship directly before it sinks, as well as its final plunge to the bottom of the Atlantic, involved a tilting full-sized set, 150 extras and 100 stunt performers.
A few attempts to film this sequence with stunt people resulted in some minor injuries and Cameron halted the more dangerous stunts. The risks were eventually minimized "by using computer generated people for the dangerous falls".
4) Long shots showing the whole ship's exterior were produced by Digital Domain. A 1/20 scale model was filmed and computer-generated images of people, ocean and smoke were added.
5) Rereleased in stereoscopic 3d in 2012.
5) "Banned from the Ranch Entertainment" one of the companies who did CGI for this film also did CGI for Spawn (1997).
7) Another notable film with realistic CGI water is "A Beautiful Mind" (2001) (Scene with baby in bathtub).
