Dans l'émission Faux Raccords n°35 diffusée par le site AlloCiné, les auteurs de l'émission pointent quelques anachronismes dans le film : Jack évoque une partie de pêche au lac Wissota (Wisconsin, États-Unis). Or, le lac en question est un lac artificiel créé en 1917, soit 5 ans après le naufrage du Titanic.
De même, dans sa cabine, Rose déballe un tableau de Picasso, Les Demoiselles d'Avignon. S'il est possible que Rose ait acquis le tableau (peint en 1907), il n'est pas possible que celui-ci ait disparu dans le naufrage du paquebot. En effet, Les Demoiselles d'Avignon a été acheté par le Museum of Modern Art de New York en 1939.

TRIVIA
-At the TED conference in February 2010, James Cameron stated: "Secretly, what I wanted to do was I wanted to dive to the real wreck of 'Titanic'. And that's why I made the movie". The statement brought laughter and applause.
-Several scenes show all four funnels smoking but the smoke from the fourth funnel is fewer and cleaner. The White Star Lines competitors all had four and they did not want to lose face. So the fourth funnel was designed as additional storage space that was used on the first trip for livestock and to provide ventilation.
-James Cameron met his fifth wife, Suzy Amis, on the set of this film. Of all his marriages, theirs has lasted the longest.
-James Cameron supervised all of the underwater shots of the Titanic himself.
-Despite the fact that this was filmed in Super 35, "Filmed in Panavision" is listed in the end credits.
-James Cameron instructed the actors playing the officers to keep order amongst the extras in the sinking scenes. Jonny Phillips ad-libbed the moment when he whips around with the gun and shouts "keep back, or I'll shoot you all like dogs!" After the take, James Cameron ran up to him and told him it was great and to do it again, and Phillips asked "What did I say?", having been too caught up in the moment to realize what he was doing.
-Tom Wilkinson was considered for the role of Lovejoy, which eventually went to David Warner. Wilkinson went on to do Full Monty - Le grand jeu, which became one of Titanic's contenders at the Oscars next year.
-Nicole Kidman, Madonna, Jodie Foster, Cameron Diaz and Sharon Stone were all considered for the role of Rose.
-The film was re-released on April 6, 2012 in 2D, RealD 3D and IMAX 3D to commemorate the 100th anniversary of the sailing and sinking of the ship and of the foundation of Paramount Pictures.
-Rufus Sewell and Jason Isaacs were both considered for the role of Cal.
-The scale model of the under water wrecked ship, has been on display in the Titanic museum in Branson, MO for a number of years. In August 2011, it will be removed and taken back to Hollywood where it is to be used to film the new Titanic 3-D movie.
-Upon sighting the iceberg, the ship's officers shout 'Hard a starboard' at the helmsman, but the helmsman turns the wheel to port. The ship did actually alter course to port and then Murdoch attempted to 'starboard the ship' to swing the stern clear of the iceberg. Titanic's steering followed the old British practice (derived from sailing ships) that turning the wheel to starboard would make the rudder and thus the ship turn to port. Conversly, turning the wheel to port as the helmsman is shown doing would make the ship turn to starboard.
-The highest-grossing film ever to win the Best Picture Academy Award, and one of only two Best Pictures to gross over $1 billion (the other being Le seigneur des anneaux - Le retour du roi).
-There was a scene storyboarded, in which Rose was to walk off the Carpathia and disappear into the crowds. Since the budget had run so high, however, James Cameron had to cut this scene due to the expense of having almost 1,000 extras brought to New York to film just 30-seconds.
-During the lunch scene, the line "Freud? Who is he? Is he a passenger?" was an ad lib by Jonathan Hyde.
-David Warner and Billy Zane both starred in Twin Peaks: Episode #2.16, although their characters do not interact.
-The line, "I'd rather be his whore than your wife", was originally spoken by Peggy Lipton as Norma Jennings in Twin Peaks: Episode #2.16.
-Barbra Streisand was considered for the role of Molly Brown.
-Adrian Paul was considered for the role of Caledon 'Cal' Hockley. As was Jack Davenport, but he was deemed too young.
-James Cameron regular Jenette Goldstein appears in period costume here. Ironically, she had showed up in period costume at the auditions for Aliens - Le retour, her first movie with Cameron, thinking it was a period movie.
-The opening was originally going to be an Irishman painting the word 'Titanic'. During that same scene, it is not, as believed by some, a real tape from her departure in 1912. James Cameron wanted to use actual footage, but at the time there was none. So he attempted to create what he thought took place. However after the movie was released, some actual footage was discovered.
-In a 2012 interview on MTV News, shortly before the movie was re-released in 3D, Kate Winslet admitted that she strongly dislikes the song "My Heart Will Go On," which was recorded by Céline Dion and prominently included in the film. She said about it, "I wish I could say, 'Oh listen, everybody! It's the Celine Dion song!' But I don't. I just have to sit there, you know, kind of straight-faced with a massive internal eye roll... It haunts me."
-In 2012, Entertainment Weekly reported that when the movie was re-released in 3D, director James Cameron didn't update any effects or fix any errors except one. When astrophysicist Dr. Neil deGrasse Tyson, director of New York's Hayden Planetarium, first saw the movie in its original theatrical release, he noticed that the configuration of stars in the night sky during Rose's night in the water bore no resemblance to what the sky really looked like over that place on that night (and, in fact, the same incorrect set of stars had just been duplicated in post-production).

Tyson wrote a letter to James Cameron explaining the error; several years later, upon meeting Cameron in person, Tyson repeated his complaint; and then at an event that occurred at the Hayden Planetarium, Tyson spoke about it to Cameron a third time. Finally, a post-production technician working on the re-release called Tyson and asked him to provide a picture of what the sky really would have looked like, and Tyson's star image was used to fix that shot. Ironically, before the shot was fixed, the stars were arranged to look like the Heart of the Ocean necklace.
