 Editing and post-production work on Alien took roughly twenty weeks to complete. Terry Rawlings served as Editor, having previously worked with Scott on editing sound for The Duellists. Scott and Rawlings edited much of the film to have a slow pace to build suspense for the more tense and frightening moments. According to Rawlings: "I think the way we did get it right was by keeping it slow, funny enough, which is completely different from what they do today. And I think the slowness of it made the moments that you wanted people to be sort of scared ... then we could go as fast as we liked because you 've sucked people into a corner and then attacked them, so to speak. And I think that's how it worked." The first cut of the film was over three hours long; further editing trimmed the final version to just under two hours.
