What happens when you take scenes from a Soviet propaganda piece and mix it with newly shot footage of monsters directed by Francis Ford Coppola? You get this incredibly enjoyable sci-fi tale that re-edits the Russian film "Nebo Zovyot" to create a tale about a race to Mars by a pair of rival superpowers and the various problems they encounter along the way. Roger Corman-produced schlockfest stars Ivan Pereverzev. AKA: "The Heavens Call," "The Sky Calls," "The Sky Is Calling." 67 min. Standard; Soundtrack: English. Plays All Regions.
