What are the most successful movies?

American movies are the most popular films around the world. The most successful movie of the twentieth century was Titanic. People around the world paid almost $2 billion ($2,000,000,000!) and they saw the famous ship sink again. Titanic was more popular than Star Wars: Episode 1. This Star Wars film made almost $1 billion in the late 1990s Close behind this was Jurassic Park, a film about dinosaurs. And it's interesting that Titanic was also the most expensive film: it cost $200 million ($200,000,000) to make.
