According to Ballard: "1 Alphaville (Jean-Luc Godard, 1965): Godard's vision of a theoretically happy but infinitely tragic computerised future brilliantly creates the future rather than just commenting on the present.
2 Mad Max 2 (George Miller, 1981): By far the best of the MadMax series. With its insane vehicles and fearful body-armour, it is a vision of Armageddon as auto-geddon. Mad Max 2 is punk's Sistine Chapel.
3 The Man Who Fell to Earth (Nicolas Roeg,1976): The visionary British director Nic Roeg always gets the best out of musicians-turned-actors. David Bowie is perfect as the alien destroyed by an uncomprehending Earth.
4 Dark Star (John Carpenter, 1974): Dark Star is the Catch 22 of outer space. It's a dazzling farce, and another icon of the US counter-culture. It was made for a mere $60,000 by a group of Californian students.
5 Barbarella (Roger Vadim, 1968): Sex, almost for the first time, made an appearance in science-fiction cinema when Vadim directed his wife, Jane Fonda, in her classic striptease sequence in a fur-lined spaceship.
6 Dr Strangelove (Stanley Kubrick, 1963): Stanley Kubrick's black satire about an insane US Air Force general who launches a nuclear attack on the Soviet Union. The death of mankind is treated as the last sick joke.
7 Alien (Ridley Scott, 1979): This is a tour de force of pure horror in which Sigourney Weaver plays science fiction's first feminist heroine. The alien came from the imaginings of the Swiss designer HR Giger.
8 The Incredible Shrinking Man (Jack Arnold, 1957): This is a classic, and a deeply poetic story of an individual's quest. Jack Arnold also directed It Came from Outer Space and Creature From the Black Lagoon.
9 Close Encounters of the Third Kind (Steven Spielberg, 1977): From the same year as the first of George Lucas's Star Wars films, this is a fable in which America learns to love the universe. It is the most deeply felt of all Spielberg's films
10 Solaris (Andrei Tarkovsky, 1972): The original, directed by Andrei Tarkovsky, not the Steven Soderberg re-make. Loss, memory, desire and the mystery of identity: the greatest Russian science-fiction film."
