Analysis of the opening sequence of Alien

Alien (Ridley Scott, 1979) which was directed by Ridley Scott in 1979 used very eerie sounds combined with squeaky noises which sound quite a strange mix which implies it would be a very fictional film. There is no sign of life until the end of the opening sequence, and even then we don’t know who these people are and don’t hear them speak, so it’s completely non-diagetic sounds. There was no establishing shot at the beginning and goes straight into a close-up of the spaceship travelling through space (which could be anywhere in the universe and full ship is never shown); and then a close up of all the equipment, and everything is very plain and metal with nothing personalised which creates an unease for the audience as everything seems very secretive, and as though whoever or whatever is on the spaceship doesn’t want anyone to know anything about them.
