"Ridley is the godfather of sci-fi movies in a way, and just him going back, that's major," says Noomi of Scott's first sci-fi flick in three decades. "I'm really excited. I really think this movie is going to be something that people haven't seen before."

"I think people are going to be really excited, and I think they're going to be pleasantly surprised," says Charlize. "I feel like that will be the thing that people will be the most satisfied about, the fact that [Ridley] didn't just go back to his Alien days and he's not just giving us that again. He's really giving us something that's very, very original in that world."

"I'm not necessarily a film geek, but I went to Comic-Con earlier in the year to promote another film, and everyone was like, ''Yeah yeah yeah yeah, tell us about Prometheus,'" says Guy. "People are waiting for this. It's very fascinating to see what we've had to protect ourselves from during the making of the film."

Prometheus stars Charlize, Noomi, Guy, Michael Fassbender, Idris Elba and Logan Marshall-Green in a story of groundbreaking mythology, in which a team of explorers discover a clue to the origins of mankind on Earth, leading them on a thrilling journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race.

So why did Ridley finally return to sci-fi after three decades? "That's really kind of what stopped me doing science fiction, because I thought, 'How is it going to be different? How is it going to be new?' And I think we've tackled a lot of new ground, which opened up the door to a kind of different form of thinking. Get bolder, get braver, dare to talk about who made us and who made them."
