Nitpick: When Augustus tells Fabius Maximus that he's seen an omen of his coming death, an eagle circling the Temple of Agrippa and then landing on the "A" of the Temple's dedication, Fabius tells him that Augustus can't be sure of his interpretation of the augury because he's not an expert. But Augustus, like most of the pre Christian Emperors of Rome, was also Pontifex Maximus, the chief priest of Rome. As such he would be very familiar with interpreting auguries, and ought to be considered an expert on the subject.
Factual Error: The poet Horace is shown to be active 17 years after his historical death. Horace actually died only a few months after his patron and Livia's first victim, Maecenas.
Factual Error: The historical timeline of Julia's banishment and her sons' deaths is altered for dramatic purposes.
Sian Phillips, who plays Livia, is three years younger than the actor (George Baker) who plays her son Tiberius.
All of the footage obtained for this cancelled film survives.
Merle Oberon was injured fairly severly in an auto accident during production, which gave the producers and crew an excuse to abandon the troubled project.
This was to be an epic film, directed by Denis Kavanagh and Josef von Sternberg.
