Tell some amazing facts about Movie Titanic ?

16. After finding out that she was going to be naked in front of Leonardo DiCaprio, Kate Winslet decided to break the ice by flashing him the first time they met.

James Cameron insisted on Leonardo DiCaprio but the studio actually wanted Matthew McConaughey. Jeremy Sisto also did a screen test with Kate Winslet, but they apparently didn't have much chemistry.

Third-class passengers could hear the loud roar of the ship's engines in their cabins at all times.

17. The ship exterior set was constructed in a tank on a beach south of Rosarito, Baja California, Mexico.

Only two bathtubs were available for more than 700 third-class passengers — one for men, one for women.

18. The entire set was mounted on hydraulic jacks and could be tilted up to 6&degrees.

Gates separating the third-class spaces from the other classes were kept locked even after the collision, according to some firsthand reports.

20. In the scene where the water comes crashing into the Grand Staircase room, the film makers only had one shot at it because the entire set and furnishings were going to be destroyed in the shot.

About 42% of the second-class passengers aboard survived.

22. Robert De Niro was offered the role of Captain Smith but turned it down due to a gastrointestinal infection at the time.

About 25% of the third-class passengers survived

23. The stuntmen in the engine room scenes were only about 5 feet tall to make the engine room look bigger.

The iceberg was spawned from a glacier in Greenland.

24. The film was originally called "Planet Ice".

One recent scientific theory holds that the moon's extremely close approach to Earth on Jan. 4, 1912, created such strong tides that it sent an array of icebergs south into the Titanic's path.

25. James Cameron spent more time with the ship than its living passengers did.

The Titanic's launch was delayed by six weeks because her sister ship Olympic needed repairs in the same dry dock. That delay put seasonal icebergs right in the Titanic's path.

26. After James Cameron finished the script, he discovered that there was a real "J. Dawson" who died aboard the Titanic.

Titanic Capt. Edward Smith did try to avoid ice danger by altering the ship's course to the south after receiving warnings of icebergs from other ships.

27. Most of the decor on the ship was under the supervision of researchers of the White Star Line, the original company which constructed and furnished the Titanic.

At 11:40 p.m., Frederick Fleet was the first person on the Titanic to see the iceberg, describing it as something "even darker than the darkness."

At 32 degrees, the iceberg was warmer than the water Titanic passengers fell into that night. The ocean waters were 28 degrees, below the freezing point but not frozen because of the water's salt content.

28. The piece of wooden paneling that Rose floated on after the sinking is based upon a genuine artifact that survived the sinking and is on display at the Maritime Museum of the Atlantic in Halifax, Nova Scotia.

A recent story in Smithsonian magazine theorizes that atmospheric conditions on the night of the sinking created optical illusions that prevented the Titanic's lookouts from seeing the iceberg.

30. James Cameron did not want to include any song in the film.
