In the film, the Roman legions withdraw from Britain in AD 467; in reality, this was completed in the year 410, nearly 60 years before. Similarly, the opening text dictates that ""King Arthur and his Knights rose from a real hero who lived [...] in a period often called the Dark Ages"". The film, however, is set in 467. Some count the Dark Ages as being in Sub-Roman Britain after the last Emperor of the Western Roman Empire, Romulus Augustus, was deposed by Odoacer in 476, nine years after the date for the setting of the film. The current Roman Emperor in the film's time would have been Anthemius.
