Jindrich Polak's Ikarie XB1 (1963) (which was released in the United States in dubbed form as Voyage To The End Of The Universe), tells of an epic space flight with a twist. A group of travellers on an immense 25th century spaceship, making a voyage across galactic distances to "the Green Planet." Along the way, they must battle their own internal demons and jealousies, and face various threats, including a derelict spaceship whose crew died of apparent radiation poisoning. They survive these encounters reasonably intact as a crew, and prepare to land on the planet intended as their new home, where all of the problems that destroyed their original home world will have been solved. To tell more would spoil the fun -- and there is a considerable amount of it, along with adventure -- in seeing this superb piece of Czech filmmaking, which incorporates elements that will seem familier to us from The Twilight Zone, Forbidden Planet, and 2001: A Space Odyssey (which was made five years later than this movie).
