A giant spaceship carrying colonists to a new planet runs into unexpected troubles on its journey, ranging from encounters with abandoned alien craft to malfunctioning onboard computers and tensions among its crew and passengers. This is the orginial version shown in theaters in 1963 with English soundtrack (no sub-titles). Quality is alittle fuzzy but otherwise good.
