Commodus: What is your name, gladiator?
[Maximus turns away.]
Commodus: How dare you show your back to me! You will remove your helmet and tell me your name!
[Maximus slowly turns and removes his helmet.]
Maximus: My name is Maximus Decimus Meridius, Commander of the Armies of the North, General of the Felix Legions, loyal servant to the true emperor, Marcus Aurelius. Father to a murdered son, husband to a murdered wife. And I will have my vengeance, in this life or the next.
In the "Battle of Carthage" in the Colosseum, one of the chariots is turned over. Once the dust settles you can see a gas cylinder in the back of the chariot.
The original ending for Gladiator was that Proximo would live and he would bury the figurines in the sand of the Coliseum. However, Oliver Reed's death during filming required the ending to be changed.
