My favourite film is 'Avatar'. It is a James Cameron's science-fiction film.
In 'Avatar' Sam Worthington is Jake Sully, who's have got a own avatar. He meet a Neytiri (Zoe Saldana) in Pandora's World. They're fall in love. Some people want to destroy a village. They're want to make money. Two worlds make a war. The Blue Humans win the war and Jake & Neytiri're happy.
I like this film because it has got a lot of sounds, graphics 3D effects. It is good for you, if you like a SF films.
