The general who became a slave. The slave who became a gladiator. The gladiator who defied an emperor. Striking story! But now, the people want to know how the story ends. Only a famous death will do. And what could be more glorious than to challenge the Emperor himself in the great arena?
~ Commodus plans about Maximus.
Lucius will stay with me now. And if his mother so much as looks at me in a manner that displeases me, he will die. If she decides to be noble and takes her own life, he will die. And as for you, you will love me as I loved you. You will provide me with an heir of pure blood, so that Commodus and his progeny will rule for a thousand years. Am I not merciful? AM I NOT MERCIFUL?
~ Commodus to his sister Lucilla.
They tell me your son squealed like a girl when they nailed him to the cross. And your wife moaned like a whore when they ravaged her again and again... and again.
~ Commodus taunting Maximus about killing his family.

Marcus Aurelius Commodus, also known as Emperor Commodus or simply Commodus, is the main antagonist of the 2000 Oscar winner historic action film Gladiator.

The only son of Roman emperor Marcus Aurelius, Commodus is also the black sheep of his family: he is a ruthless, amoral and unstable man who lusts after his own sister and thinks of himself as a god.

He was portrayed by Joaquin Phoenix.


The general Maximus, weary of battle, decides to retire at his Spanish farm estate at the Emperor's behest, but the Emperor tells him that Commodus is unfit to rule and thus appoints him as regent to help save Rome from corruption. When Marcus Aurelius tells Commodus his decision, Commodus - who has always felt unloved and ignored by his father - flies into a rage and strangles him.

After mourning his father's death, the new Emperor asks Maximus for his loyalty, but the general suspects foul play and refuses. Soon after, Commodus has Maximus arrested and orders him executed at dawn. Maximus manages to escape and makes the long journey to his farm on horseback, but arrives too late; Commodus' men have burned it to the ground and murdered his wife and son.

Meanwhile, Commodus returns to Rome to a cheering crowd and is met by his senators, who have grave concerns about his fitness to rule. Commodus orders 150 days of gladiatorial combat in honor of his late father. Commodus watches as a troupe of gladiators fight in the Colisseum, depicting a battle between Carthaginian infantry and Scipio's legionaries. When the team portraying Carthage defy expectations and win, Commodus comes into the arena to personally congratulate them, along with his young nephew Lucius. The leader removes his helmet to reveal that he is in fact Maximus, alive and well, and vows to avenge his family by killing Commodus. As the Praetorian Guard prepares to kill him, the crowd chants "Live!". Commodus reluctantly allows Maximus to live.

Next, Maximus is pitted against the formidable Tigris of Gaul, an undefeated gladiator. After a fierce and lengthy duel, Maximus is able to gain the upper hand, but spares his opponent's life despite the crowd's urging that he kill him. Angered, Commodus berates him, even taunting him with harrowing details of his family's death. Undaunted, Maximus turns around and walks away. This act of defiance, along with his victory over Tigris, makes him more popular than the Emperor himself.

Commodus' sister Lucilla and the chief senator Gracchus secure a meeting with Maximus, and he obtains their promise to help him escape Rome, rejoin his soldiers, topple Commodus by force, and hand power over back to the Senate. Commodus suspects Lucilla of betraying him and threatens to kill Lucius unless she tells him about the plot. He then dispatches his men to arrest and/or kill the conspirators. Gracchus is quickly apprehended, while a contingent of Praetorians is sent to Maximus' quarters. Maximus reaches the rendezvous point but falls into a trap; his ally Cicero is killed and he is captured.

Commodus, jealous of Maximus' growing popularity, challenges him to a duel in the Colosseum. Before the fight, he stabs Maximus on the side to put him at a disadvantage. During the fight, however, Maximus manages to evade Commodus' blows and disarm him. Commodus orders the Praetorians to give him a sword, but they rebel against him and stand aside. He produces a hidden stiletto, but Maximus turns the blade back into his throat, killing him. Shortly after, Maximus succumbs to wound inflicted by Commodus.


Commodus' most deep ambition was Aurelius approval as a father, but he had a obnoxious (yet fair) outlook about his son. He was not only power-hungry, but also mentally unstable. He rarely controlled himself even in public. The worst traits about his personality was his sadism and his psychotic outbreaks which shows during the film, and his worst shortcoming was his lack of approval. Commodus used the Arena spectacle saying that the only thing Rome needed is a little bit of entertainment, that of course was a delusion and his ultimate goal was being acclaimed by the crowd of Rome. His continuous irresponsible uses of the Capital's extravagance showed to the senate why his father would never choose Commodus as a emperor.

Maximus was the son that Marcus Aurelius really wished he had, he despised him the most, due to his jealousy towards him. He constantly tried to ruin the image of Maximus, putting himself in danger and sacrificing other people's life as a cost. But during the film, Commodus began to show his true reason about destroying Maximus' image. He really saw why Marcus Aurelius preferred Maximus over him; Maximus was loyal, brave, rational, careful and strong, while Commodus was cowardly and unstable. His cowardice got the best of him before and during the final fight with Maximus. He wounded Maximus before the fight since he was afraid that otherwise Maximus would quickly kill him. Also, after Maximus disarmed him during the fight, Commodus was too afraid to recover his own sword and started desperately ordering Quintus and other Praetorians to give him another sword.

As for his relationships, the only people he ever loved were his father and his sister, Lucilla. But after all the love for his sister began to turn into an insane dominance, lust and an incestuous relationship, after that and knowing that her brother was the responsible for Marcus' death, Lucilla saw her brother as the monster he truly was.



  • The real life Commodus was also mentally unstable and delighted in fighting in the coliseum. However, he never died in the Arena. Instead he was killed by strangulation and poisoning.
  • Jack Gleeson, the actor who portrays Joffrey Baratheon in the TV series Game of Thrones, mentioned that Commodus and Hexxus, the main antagonist of the animated film Ferngully, were the two villains that impacted him the most as a child.
