Of all the onscreen portrayals of Commodus, Sergio Ciani's is probably the closest to the real emperor. The real Commodus was athletic and muscular. In reality, Commodus, as in the film, did enjoy performing as a gladiator. He was also said to have been a skilled swordsman and marksman.
But he wanted to take our women!
Ursus: In a way I can't blame him... he shows rather good taste!
In the film Marcus Aurelius' dying wish is that Commodus keep peace. Instead Commodus begins attacking villages. In real life it was actually the opposite. The real Commodus ended the fighting when he became emperor. His reign was a time of peace. He did not pursue his father's wars and he organized a truce with the Danube armies Rome was fighting.
