For the US version, distributed by Joseph E. Levine's Embassy Pictures, the dragon footage at the beginning has been removed and replaced with the dragon footage taken from Pietro Francisci's Hercules (1958), which Levine had also distributed in the US.
Submitted to the British Board of Film Censors by Golden Era on 31 July 1964 and passed with a "U" certificate. The London preview was at the Rank private theatre in Wardour Street on 12 August 1964 (one showing at 2:30 pm for press and trade only). Thereafter, for the remainder of 1964, the film was distributed round the UK in no particular order and in no particular hurry, eventually arriving in London at the Lido, West Ealing, week commencing 3 January 1965.
Most of the cryptic pseudonyms used in this movie have now been identified. Of the few that remain, film journalists in Italy believe that co-writers "Kirk Mayer" and "Pat Kein" were in fact husband and wife team Antonio Leonviola and Sofia Scandurra. Unfortunately, investigators are still stumped on mysterious director of photography "Claude Haroy" who does not seem to exist anywhere else in any capacity. Since the job of DP on an Italian epic was unlikely to have been given to a one-off beginner, the best speculation is yet another pseudonym for cinematographer-turned-director Alvaro Mancori who was making his directorial debut here as "Al World."
