the product of a filmic stereotype whereby historical films depict peoples of antiquity wearing such bands. Although the film is set within the 2nd century AD, the Imperial Gallic armor and the helmets worn by the legionaries are from AD 75, a century earlier. This was superseded by new designs in AD 100. The legions' standard bearers (aquiliferi), centurions, mounted forces, and auxiliaries would have worn scale armour, lorica squamata. The Germanic tribes are dressed in clothes from the Stone Age period. Roman field artillery was used in combat quite extensively by the Romans, though within the film they are also depicted as using onagers, which would not see use by the Roman Empire until the 4th century, hundreds of years after the events of the film. The Roman cavalry are shown using stirrups. This is anachronistic in that the horse-mounted forces of the Roman army used a two-horned saddle, without stirrups. Stirrups were only employed in filming for safety reasons because of the additional training and skill required to ride with a Roman saddle. Catapults and ballistae would not have been used in a forest. They were reserved primarily for sieges and were rarely used in open battles. Fire arrows and canisters fired from catapults were not used at any point in ancient history. The Praetorian Guards seen in the film are all wearing purple uniforms. No historical evidence supports this. On campaign, they usually wore standard legionary equipment with some unique decorative elements. Home media Gladiator was first released on DVD and VHS on November 21, 2000. Along with X-Men, both films generated $60 million in home video sales each in their first week. By this point, Gladiator had already sold 1.8 million DVD units, making it the fastest-selling DVD release. By January 2001, it would go on to break The Matrixs record for becoming the top-selling DVD release, selling 3.5 million copies. With over 5 million copies sold, the film would hold the record for being the best-selling DVD title of all time until Shrek surpassed it later that year. The DVD has since been released in several different extended and special edition versions. Special features for the Blu-ray Disc and DVDs include deleted scenes, trailers, documentaries, commentaries, storyboards, image galleries, Easter eggs, and cast auditions. The film was released on Blu-ray in September 2009, in a 2-disc edition containing both the theatrical and extended cuts of
