The cruise ship in the film, the Legacy, bears a very strong resemblance to the Titanic and her sister ships Olympic and Britannic -- the Legacy just has five funnels instead of four like the ships Lusitania and RMS Mauretania, and is rather cartoonishly shorter and fatter than the real-life ocean liners.
