I love science fiction but I don't like fantastic [cinema]. For example, if you have a magical ring and you can explode the world with it. What are we talking about? You know, it's not interesting. I don't like Lord of the Rings. Even Star Wars, for me, I don't understand this kind of story. But Alien, because the rules of the game are very precise, it could happen. I love science fiction. I have an idea about robots in the future.
