I saw a lot of films, but I think that my favourite is "Titanic". It tells a story of a famous ship, which sank in 1912. The "Titanic" was a colossal ship, even by modern standarts. It's tragic sinking will always be remembered, for the ship went down on the first voyage with heavy losses.
The director of film - James Cameron. The main parts of the film are played by young Leo Di Caprio and Kate Winslet. So I think it's really great film with great actors.
