Copyright dated 1963, but not submitted to the British Board of Film Censors until 27 June 1975 when it was passed with a "U" certificate under the title Revenge of the Gladiators. Distributors Miracle Films selected it to go out with Maciste contro i mostri (1962), but the release was limited. The ITV network eventually acquired the film and its television premiere (under the title Fire Over Rome) was on 30 September 1991 throughout most ITV regions, excluding Yorkshire Television who saved it until 11 November 1991 to be screened as the third of their "Roman Follies" series, (a light-hearted season of the worst of the Italian epics).
The film was unreleased in the UK until 1975 when it was finally issued under the title "Revenge Of The Gladiators", and played as a supporting feature to "Land Of The Monsters" (itself a retitling of the 1962 feature "Colossus Of The Stone Age").
The Emperor Nero's full name was Lucius Domitius Ahenobarbus.
The Christians in Rome were persecuted by Nero after rather than before the Great Fire of Rome in 64 AD because he blamed the widespread devastation it caused on them.
