It is often debated among fans whether Vickers is a human or merely another android like David, albeit a more advanced model. Evidence for being human: Vickers sleeps in a cryo-chamber in the beginning of the film, something which is not necessary for an android as they do not require sleep. Vickers is later seen doing push-ups to presumably work off the disorientation from hypersleep. When Janek informs some of the crew members at the Engineer ship of a storm incoming, Vickers can be briefly seen in the background, exhaling cigarette smoke, showing that she is a smoker. It is implied in one scene that Vickers engages in intercourse with Janek, although this is never referenced again. Originally, footage was filmed of Vickers telling Janek, "You were a terrible lay, by the way," before she heads to the escape pod when Janek elects to crash the Prometheus, but it was removed from the final cut. Vickers constantly expresses emotions such as anger and shock and also expresses fatigue during the more physical scenes; David shows no emotions or fatigue. Vickers expresses jealousy when Peter Weyland states David is the closest thing he'll have to a son. Vickers calls Weyland her father. Vickers and Weyland constantly argued over the ownership of Weyland Corp as stated in the film. When Holloway ask David why he wears a space suit, David says that it is to blend in with humans, implying that it is not necessary for androids. If this is the case, Vickers would not have bothered to put on a space suit when fleeing the Prometheus. Damon Lindelof, the co-writer of Prometheus, has said that Vickers is not an android. Evidence for being an android: Janek jokingly brings up the possibility that Vickers is an android and the scene ends with the two of them heading off for implied sex which is something that is never referenced again (as stated above). Both Vickers and David refer to Weyland as their father, despite David being an android. The MedPod seen in the film is only capable of performing surgeries on males, which is very odd considering its use is for Vickers. However, it is likely the MedPod is actually for Weyland. When Weyland passes away, she expresses no emotion to the news. However, this could be a result of her deep hatred for him. Despite the fact that Vickers slept in a cryo-chamber, it is worth noting though that in Alien (1979), Ash slept in a cryo-chamber as well to hide the fact that he was an android; the same could also be applied for Vickers if she is an android. Regarding the possibility of Vickers being an android, some fans have theorized that Vickers might not be aware of the fact that she is an android and has spent her whole life believing she is a human. If Meredith Vickers is indeed an android this would make her the second female android seen on-screen in the franchise with the first being Annalee Call from Alien Resurrection (1997).
Composer Marc Streitenfeld had the orchestra play his compositions backwards, and then digitally reversed the compositions for the final film. This made the music sound unusual and unsettling, which he felt was right for the film.
Sir Ridley Scott named the film "Prometheus", seeing the name aptly fit the film's themes: "It's the story of creation; the gods and the man who stood against them." In Greek mythology, the Titan Prometheus was an immortal servant of the gods, who stole and gave to mankind the gift of God fire, an immeasurable benefit that changed the human race forever (for better and worse). It made mankind dangerous to the gods.
For the alien planet, creatures and technology, director Sir Ridley Scott instructed the design team to aim for a look that could logically come before the original Alien (1979), and thus not to rely too heavily on Swiss artist H.R. Giger's famous original planet and Xenomorph designs. However, almost all of the team's drawings eventually contained subconscious "Gigeresque" embellishments, while also drawing inspiration from several unused Giger designs for Alien. In the end, it was decided to invite Giger himself to come over, who approved of the use of his old ideas and gave additional input on reverse-engineering his original designs for the new film. Further inspiration was drawn from the works of Russian 3D artist Gutalin (Alex Kozhanov). Giger died of fall-related injuries in 2014, making this the last movie related to the Alien franchise that he worked on.
Both the "Beginning of time" sequence that opens the film and the crash sequence near the end were shot in Iceland over two weeks, after both Wadi Rum (Jordan) and Morocco were deemed too politically unstable at the time. Iceland's volcanic Hekla valley was used as the surface of planet LV-223, with rocks placed in the landscape and computer-generated images (CGI) to provide the planet's otherworldly backdrop. The Engineer's sacrifice in the opening scene was filmed at Dettifos Falls, a location so remote and hard to reach that the crew had to construct roads to get there.
To prepare for his role as the android David, Michael Fassbender watched Blade Runner (1982) (another Sir Ridley Scott film), The Man Who Fell to Earth (1976) (for David Bowie's androgynous performance), The Servant (1963) and Lawrence of Arabia (1962) (mentioned by Peter Weyland). Fassbender also studied Olympic diver Greg Louganis, drawing inspiration for David's walk from Louganis' physicality.
