The Roger Corman Russian Sci-Fi Collection (1962-1968)
In the mid-1960's producer Roger Corman purchased the US rights to a handful of Soviet science-fiction films: Planeta Bur (Planet of Storms, 1962), The Sky Beckons (Nebo Zovyot, 1959) and A Dream Come True (Mechte Navstrechu, 1963). From these three Corman fashioned four "new" films: Queen of Blood (1966), Battle Beyond the Sun (1959), Voyage to the Prehistoric Planet (1965) and Voyage to the Planet of Prehistoric Women (1968).
