    The film is very exciting and dramatic(戏剧性的), but it is also romantic(浪漫的) and very sad. It is about the ship, the Titanic, which sank in the Atlantic in 1912. It is a love story. The two famous stars are Leonardo Di Caprio and Kate Winslett. They fall in love on the ship, but are not allowed to be together as she is rich and he is poor.
