Showing what a powerful, impressive and brilliant movie Alien is, this is the only movie on our list to have also featured in our Top 10 Sci-Fi Movies of All-Time.
Working as both a masterclass in science fiction storytelling, Ridley Scott’s Alien is also masterpiece of suspenseful horror and terror. Its slow burn and tense atmosphere leads to some of the best jump scares in the genre and it would be hard to argue that Ripley isn’t the best Final Girl to grace the silver screen (but we’ll get to that with our next entry).
