When Harry Harrison was asked to compile a list of his Top Ten favourite sf movies for The Aurum Film Encyclopedia: Science Fiction, edited by Phil Hardy, he wrote:   I find it difficult to list a top ten, but I will name the best sf film ever done. H.G. Wells' Things to Come (1936). In California I showed it to a class I was doing for teachers of sf in high schools. It was a beautifully clean print. The film itself still holds up; the acting, writing, direction - even the sets and model work. I think it belongs in the top ten best films of all time - and is certainly the sf classic.   That classic movie contains the following exchange of dialogue, which provided the inspiration for the title of one of Harrison's series of books: "There they go, that faint gleam of light!" "I feel that what we've done is monstrous." "What they've done is magnificent." "Will they come back?" "Yes. And go again and again, until the landing is made and the moon conquered. This is only the beginning." "But if they don't come back? My son and your daughter. What of that, Cabal?" "Then presently others will go." "Oh, God. Is there never to be any age of happiness? Is there never to be any rest?" "Rest enough for the individual man, too much and too soon, and we call it death. But for Man, no rest and no ending. He must go on, conquest beyond conquest. First this planet and its winsome ways, and then all the laws of the mind and matter that restrain him ... then the planets about him! And at last, out across immensity to the stars! And when he has conquered all the deeps of space, all the mysteries of time, still he will be beginning."
