Three sci-fi masterpieces from The Martian director Ridley Scott
While veteran British director Ridley Scott has made just a handful of science fiction features - technically four, including The Martian - over his four-decade career, he has managed to turn out two seminal classics and one major critical hit.
The sci-fi film that launched Scott's career, made Sigourney Weaver an action heroine, and spawned an entire horror-in-outer-space tradition, this atmospheric classic begins with a spaceship crew picking up a lifeform and escalates to some hysterically intense moments, including that chest-bursting scene.
Blade Runner (1982)
A world-weary detective (Harrison Ford) comes out of retirement to hunt down murderous humanoids known as "replicants" (led by Rutger Hauer) in this dystopian neo-noir based on Philip K. Dick's 1968 novel Do Androids Dream of Electric Sheep? and produced by Hong Kong tycoon Run Run Shaw.
It started life as a much-anticipated prequel to Alien but ends up a visually stunning 3D spectacle that hints at the cosmic history of humanity. Scott has since promised two or three more Prometheus films, the last of which would link up to Alien. Edmund Lee
