Titanic Trivia -
20th Century Fox acquired 40 acres of waterfront south of Playas de Rosarito in Mexico and started building a brand new studio in May 31 1996. A 17 million gallon tank was built for the exterior of the reconstructed ship, providing 270 degrees of ocean view. The ship was built to full scale but production design removed redundant sections on the superstructure and the forward well deck so that it would fit the tank. The remaining sections were filled in digitally. The lifeboats and funnels were shrunk by 10%. While the boat deck and the A-deck were full working sets, the rest of the ship was steel plating. Contained within that was a 50 foot lifting platform for the ship to tilt during the sinking sequences, whilst towering above that was a 162 feet tall tower crane on 600 feet of railtrack. This was used as a construction, lighting and camera platform.
All the scenes where there is an exterior sunset shot were filmed at the set in the Baja California, Mexico set. (source: imbd.com)
