For the U.S. version, titled Voyage to a Prehistoric Planet (1965), all footage of Kyunna Ignatova has been removed and replaced with footage of American actress Faith Domergue playing the same part.
Three years after this film was released in the United States in a edited and dubbed version as "Voyage to a Prehistoric Planet" (1965), the dubbed Russion footage was agained re-edited by director Peter Bogdanovich and released as "Voyage to the Planet of Prehistoric Women" (1968). For this second U.S. version, the American insert shots of Basil Rathbone and Faith Domergue were removed and new insert shots featuring Mamie Van Doren and other actresses (as inhabitants of Venus) were added. Bogdanovich also did the narration as if he were one of the Cosmonauts telling the story in flashback. The famous shot of the Venusian reflected in the pool of water was also removed.
