Visible crew/equipment: 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.

Visible crew/equipment: After the battle with the Germanians, the next morning after the tavern, he is walking in the army camp and he feeds a horse a piece of apple. If you look closely between Maximus and the horse, there is a crewman wearing a pair of blue jeans.

Deliberate "mistake": In the fight scene with the chariots Maximus takes one of the horses from a chariot and jumps on it. The horse already has a saddle complete with stirrups despite the fact it was pulling a chariot and not carrying a rider.

Continuity: After Maximus and Tigris' battle, Tigris falls to the ground and we see his mask is already up. Maximus then pulls the mask up which has magically come down over Tigris' face again.

Factual error: When a group of soldiers goes to Maximus' villa to burn it and kill his family, his son points them, saying in perfect Italian "Mama! I soldati!" I just don't understand why he speaks Italian in a movie in English, where people are supposed to speak Latin, in a province where this language was never ever spoken.

Visible crew/equipment: When Maximus is told the Emperor is dead we see him barge past Commodus to see the body. Look behind Commodus at the roof and you should see an electrical stage light.

Revealing: In the beginning of the film at the major fight sequence. When you see the Romans shield themselves with the rectangular shields against the barbarian's arrows and then they charge at each other. If you look closely enough, you can see two Roman soldiers standing there having a great laugh, one pointing a sword smiling, and the other one staring at the ground laughing to his heart's delight.

Revealing: After the final fight scene, where Maximus is dead and on his back in the sand, his armour should have made his head droop horribly backwards. To avoid that, the filming crew put a pillow of sand under his head to raise it about three inches.

Revealing: As Maximus approached his home after he should have been killed, the grain fields clearly show marks which are only caused by a tractor during crop spraying.

Revealing: When Lucilla takes her hand and closes Maximus's eyes after he dies you can clearly see him blink.

Continuity: During the first Gladiator match in Morocco, Maximus and Juba are chained together. Once they have killed the last man, the camera takes us around the arena.  You can clearly see the shadow of the camera on Maximus' chest. It happens twice.

Factual error: In one of the scenes in Rome leading up to a fight, leaflets are being handed out. These didn't exist, event notices were written up on boards.

Continuity: During the enactment of the Battle of Zama, Maximus rides his horse around a bend with his sword in his left hand. When we cut to close up, it's back in his right. Looking at the left-handed shot in freeze-frame, you can see the frame has been flipped, left-to-right (check the armor). This was probably for continuity reasons. Similarly, Maximus jumps on the horse and his shoulder protector is clearly on his injured left shoulder. However, a few frames later, the protector is on his right shoulder, then it moves yet again back the correct spot, the left shoulder.

Visible crew/equipment: During the scene where Maximus throws the sword into the crowd and yells "are you not entertained," the camera pans around, and in the crowd, for a split second, you can see a cameraman in jeans and a shirt standing next to a camera. This is visible on the big screen, but hard to see on video, unless you see it on DVD and can zoom in.

Revealing: In the scene where Maximus quickly kills all his opponents, the third to last man he kills of the group of men, when he stabs him in the stomach, you can clearly see him "stab" to the side of his stomach. Even more visible when you slow it down.

Factual error: Before Maximus enters the colliseum, he selects a helmet and places it on his head. On the rack is a copy of a saxon helmet found at Sutton Hoo, England and part of the treasure found at that location. Unfortunately this is a 7th century design.

Revealing: After the first battle in the Colosseum (The Battle of Carthage), Commodus decides to meet "The Spaniard" in the arena. When Quintus (the head of the Praetorian Guard) is telling the slaves to drop their weapons, we can see one of the spectators hiding a plastic bottle of water (right upper corner of the screen).

Continuity: In the scene where Hagen tests Maximus in the sword fighting watch closely the scene behind them. At the time when Hagen strikes Maximus for the first time you can see gladiator behind taking a glass. At the time of the second strike you can see only a glass. When Hagen stopped his third strike you can see the same gladiator holding a glass and looking around. This time he is turned toward the camera and you can see a red spot on his chest.

Revealing: Near the end of the movie, when Commodus and Maximus are in close, struggling for the knife, take a good look at the knife. Both of the actors' hands are gripping it and it's clearly rubber because it's bent at a serious angle.

Other: When Maximus enters the arena before facing Tigris, the camera pans around the crowd. At one point, you can see a young Hispanic girl wearing a "scrunchie" holding her hair in a perfect ponytail, several bracelets and a watch, a necklace, a cut-off white t-shirt, and blue jeans. Most noticeable in full screen version.
