Voyage to the Prehistoric Planet is a 1965 sci-fi film directed by Curtis Harrington. The film is actually a US adapted and edited version of the Russian sci-fi movie Planeta Bur directed by Pavel Klushantsev, with Curtis Harrington filming extra scenes featuring Basil Rathbone and American actors for the US/English speaking market. While Harrington considered Queen of Blood, another such edit, enough his film to keep his name on it, he was here credited as "John Sebastian", in homage to Johann Sebastian Bach.
