Greatest sci-fi film of all time

Rating: 10/10 (3 November 1998)

Exactly how you would expect space travel to be like - realistic and before man landed on the moon!!!!. Paved the way for every sci-fi film afterwards. Didn't need big name stars to make it one of the greatest movies of all time, anyway they would have been overshadowed by HAL and the ground breaking special effects that were only bettered 10 years later in Star Wars(and even that's debatable)......
