Conquest of Space has a script based on Chesley Bonestell and Willy Ley's extraordinary non-fiction book. Philip Yordan, Barre Lyndon, and George Worthing Yates are responsible for the adaptation of the famous book on space travel. James O'Hanlon wrote the screenplay. The scenes of visionary space craft drifting in the void of space represent the best attempt to portray space travel realistically of any film of the fifties. Byron Haskin, whose previous effort for George Pal was War Of The Worlds, directed this oddball mixture. Click for other version of poster
