The film was re-released in the United States in 1962 in an English-dubbed and slightly modified form by Roger Corman's Filmgroup under the title The Magic Voyage of Sinbad. It retains the plot structure of Sadko but includes several changes: the total running time is reduced from approximately 85 to 79 minutes (most of the deleted footage consists of scenes in which songs are performed, though one song is retained and sung in English), voice-over narration is added, the protagonist "Sadko" is renamed "Sinbad," and other characters and places are renamed to disguise the film's Russian origin and transform the film into a story about Sinbad the Sailor (perhaps most significantly, the city of Novgorod is renamed "Copasand"). In fact, the opening narration makes direct references to Ray Harryhausen’s 1958 hit film The 7th Voyage Of Sinbad, namely the battle with the Cyclops and the giant two-headed Roc bird, in an apparent attempt to cast this unrelated film as a direct sequel. The English dubbing in this version arguably gives the film a slightly "campier" tone than the original version, in which the dialogue has a more polished and literate tone. Cast and credits were also altered to made-up "American-sounding" names. The "Script Adaptor" for this version of the film, uncredited, was a young Francis Ford Coppola.
