Poseidon  -

In this remake of the original 1972 version The Poseidon Adventure, warner bros based many of its sets on rooms aboard the RMS Queen Mary. The film's set designers drew inspiration for some of the spaces aboard the fictional Poseidon from rooms aboard the RMS Queen Mary 2, most notably in the Poseidon's ballroom, which is modelled on the main dining room of the Queen Mary 2. The upside-down ballroom set was built on top of a large water tank in the sound stage so that it could be filled with water and drained in a matter of hours. The interior (and exterior) shots of the ship rolling were constructed using CGI.
