The movie Titanic premiered in 1997. In 2012, when we commemorated the 100th anniversary of the ship's sinking, many of the movies' biggest fans were shocked to find out that it was real historical event. As knowledgable as Neatorama readers are, you knew about the real RMS Titanic, but how much do you know about the film? There's always more trivia behind the scenes that you'd never know just by watching the movie. For example, it was the first film James Cameron ever made that didn't mention nuclear weapons (and he'd already made ten films). And even though there was extraordinary attention to detail, the best lines and scenes in the movie were made up on the spot. Find out which ones they were and read the rest of the 25 things at Buzzfeed.
