oh right, yes that's true. Don't go out of your way to do this, watch it again if you want if you have time, but I'm a big big fan of philosophy-laden sci-fi/horror, I think horror and sci-fi only gain meaning if they're backed by a philosophical premise or landscape in their veins. I like that Damon Lindelof (Lost was a masterpiece) and writers along with Scott directing made it so the philosophical aspects, whichever one, were all diluted as I said into the flow of the film. It wasn't like 'Inception' where the movie would stop and explain to you "okay, so blah blah blah, and then blah blah..." which was an incredibly clumsy movie and I'll stop there for Inception; Prometheus is clearly a big as$ blockbuster, it's Hollywood, it's huge, but they used that polished quality to engineer a clever, unpretentious film with great attention to detail with a philosophical trait as a backbone in separate scenes but the whole of it also.
Examples:
Fassbender the robot wears an oxygen helmet before leaving the ship. That Tom Hardy look-alike tells him "you don't need a helmet, you're a robot. you don't breathe oxygen". To which 'David' replies "I only wear it to fit in with you. Humans don't like to see things that aren't like them and it makes them more comfortable". Very, very clever little scene, full of meaning, an interrogation in itself.
Or the idea David is more than a mere robot, with somewhat of a conscience or a conscience about a conscience, and though this is an utterly classic theme in sci-fi, was cleverly inserted into the movie. When old Guy Pierce's hologram appears early in the film to explain the goal of the expedition, he says something like "David is the closest thing I've had to a son. And yet, he'll lack the one thing that makes us all human. A soul." after which David's smile withers away as he wears a more somber expression.
To add to this, David is also very curious, and the movie hints, more than his computer chips alone make him. Like there's something more to him than what he was programmed to be. Like a sentient will of its own to become human, and that's the whole 'Robot wants to be man', Pinocchio theme, so nothing new but well done.
David has a taste for softness, love and aesthetics. When the engineer caresses his head (that doesn't end well...) he smiles as if *feeling* the grace of his creator, or when he's in the engineers' operation room and he fondly discovers their technology, the blue holographic virtual modules...
Anyways, this is TRF not IMDb, I'm just extending to you some of the very well incorporated ideas into the volume of the film. And of course, Prometheus, the story in Greek mythology, and the first scene of this film...interesting.
