It is well documented that Messala's horses in the chariot race were dyed black (their natural color was brown). They appear solid black during the pre-race procedures. During the race, when the horses are running flat out, most of the dye wore off and in closeups, they appear to be brown.
Sheik Ilderim pins a Star of David onto Ben Hur's belt before the race, obviously to goad the Romans. The Star of David didn't become a symbol of Judaism until the Middle Ages, in Eastern Europe. The first reference occurs in the 12th Century.
Roman warship rowers were not slaves but a paid part of the ship's crew.
When Judah and Messala argue in the courtyard of Judah's home, road noise and honking horns from cars can be heard in the background. For some reason, it was not removed from the soundtrack in post prodction.
A character refers to the Roman Emperor as "The Divine Tiberius." Although Tiberius was never deified in life (it was a posthumous honour), he claimed descent from the Roman deities Jupiter and Venus, so he was "divine" in that sense. Tiberius' successor Caligula claimed in his madness to be all gods at once, and Caligula's successor Claudius I was the first of the office to be formally deified during his lifetime.
Jesus' ministry seems to last 5 years in this movie. Although this is traditionally seen as lasting only 3 years, the Bible gives no such specific chronology, Making it 5 years is a reasonable artistic decision.
During the chariot race just before Ben-Hur's chariot jumps the wrecked chariot, stunt driver Joe Canutt can be seen dropping the reins and grabbing hold of the side of the his chariot (his father, stunt coordinator-2nd unit director Yakima Canutt, had instructed him to grip the underside of the chariot's railing. Joe ignored him, or forgot, and grasped the railing from the top, and was vaulted over the top of the chariot, which could have been fatal had his quick reflexes and strength not allowed him to haul himself back over the vehicle's yoke before he fell between the horses and chariot).
Modern books with covers can be seen, at a time when only scrolls and folders with single pages were used.
When Esther and Tirzah and Miriam seek shelter, the storm is violent enough to cause earth to fall in front of the cave, and the sound of the wind is deafening. Yet trees visible in the background (from the mouth of the cave) do not so much as sway in the breeze.
The mezuzah shown at the entrance to Ben-Hur's home is mounted diagonally. That practice was not adopted until the middle ages, by Ashkenazi Jews, as a compromise between the rules offered by 2 medieval Rabbis.
In the market scene following the argument between Messala and Judah, a person is heard saying in the background 'kidhar jaata hai bhai, kidhar jaata hai' which is Hindi for 'where are you going brother, where?'. Hindi language originated much later in the 17-18th century. However, this cannot be considered a goof since the entire film is spoken in a language (English) which didn't exist in the 1st century either.
Sheikh Ilderim and Judah pronounce the name of the Sheikh's chariot horse "REEGH-el," as though it were from the Latin, with a hard "g." The four horses, as the Sheikh, are "named for the stars," and all those names -- Aldebaran, Altair, Antares and Rigel -- are Arabic names for these particularly bright stars that are still in use. An Arab would pronounce that last name as "Rijl" (REE-djl), not "REEGH-el," and Judah would likely have known that.
During the chariot race, a Volkswagen Beetle can be seen in the background.
During the chariot race, when we see the third dolphin tipped to mark the laps, the following shot briefly shows the dolphins with the third still up.
As stated, the MGM lion is a frozen frame as the film opens - Leo doesn't roar. This was not done as suggested to convey calm or out of respect for the religious theme, but because Wyler wanted to open the very first frame of the film with Rózsa very dramatic score. For this to be fully effective, the roar had to go. This very similar to what Fox did with 'The Robe', another religious themed epic opening immediately with the Newman score on the very first frame and skipping the standard Fox logo and fanfare track.
In the film's prologue, Balthasar the narrator, telling the story of Jesus's birth, begins the story with the Roman census "in the seventh year of the reign of Augustus Caesar." In fact Augustus had been emperor of Rome for at least 20 years at the time.
When Ben-Hur's and Messala's chariots lock wheels, Messala's wheel shatters. In the shot of the overturning chariot, the wheel is intact.
At sheik Ilderim's oasis, Ben-Hur's facial hair changes length between shots.
The final chariot race was supposed to been held in Jerusalem, but there was no such structure in that city. The only two chariot race courses ("Circus") in Israel (Judea) were both in the coastal city of Caesaria near present-day Tel-Aviv.
Nine chariots start the chariot race. After the first crash, there appear still to be nine chariots in the race. After the third crash, six are shown, but as Ben Hur passes to catch up, clearly there is a total of seven in the race. After five have crashed, five are left. Messala is the sixth chariot to crash, but Ben Hur and three others finish the race. Thus, nine chariots start the race, six crash, and four finish.
As they are preparing for the chariot race, a raised platform is shown which is made of galvanized steel.
In the chariot race Ben Hur and Messala are side by side for several laps. When they turn corners they remain side by side.
When Judah visits Messala after the chariot race, as he enters the room he lays his wreath on a chair next to the door. When he leaves, the wreath is missing.
Messala damages Ben-Hur's chariot with his saw-toothed wheel-hubs, but when Ben-Hur drives up to Pontius Pilate to receive his prize, his chariot is undamaged.
When Judah and Messala hurl their spears at the beam, both spears travel to their mark on guide wires. This is obvious because there is no arc in the trajectory of the spears.
A close-up of the saw-toothed wheel hubs, just before the race shows the modern welding.
The calf in the stable is a Holstein, a breed that did not exist at the time, and was unknown in the area until 1922.
During the scene in which Judah and Arrius are rescued from the water, the waves breaking in the background reveal the point at which the studio tank meets the painted cyclorama.
As Judah and other prisoners are being marched away, a guard whips Judah and tells him to get back to his place, but the lips aren't saying that.
Three years after Judah serves as a galley slave he goes to Rome with Quintus Arrius presumably in 29 AD. Arrius is presented with a baton of victory by Emperor Tiberius after the former's victory against the Macedonian pirates. In reality,Tiberius had grown disillusioned with the principate after the death of his son Drusus, and left Rome for his villa on the island of Capri located off the bay of Naples in 26 AD. He never returned to Rome. Tiberius left the day to day administration of the city to the Praetorian prefect Sejanus. Therefore Quintus Arrius and Judah Ben-Hur would have been received by Tiberius on Capri and not in Rome.
When Christ is carrying His cross, the Latin title Iesus Nazarenus, Rex Iudaeorum ("Jesus of Nazareth, the King of the Jews") is written backwards. A Roman soldier is shown carrying the title ahead of Him, with the Latin characters reversed (from right to left). A few moments later the title appears again, only this time the Latin is written correctly (from left to right).
Tire tracks from the camera truck are visible in the sand of the circus during the chariot race.
As Pontius Pilate comes out to watch the chariot race and takes his seat, a Roman officer behind him calls out orders to to his men, but no sound is heard from the officer.
One of the chariot heralds has been claimed to be wearing a wristwatch, but other viewers report that this is an oddly positioned shadow.
When Messala and the sheik are betting on the race, we hear them both saying 1,000 talents, but their lips are not saying 1,000.
When Messala breaks a tile on the rooftop of the House of Hur, a broken tile from an earlier take already lies at his feet.
The shadow of the camera can be seen on Christ's back as Ben Hur is leaving Nazareth to go to the galleys (widescreen version).
As the Romans are marching to Jerusalem, Drusus asks Messala what town they are passing through. Messala replies, "Nazareth," but when he says "we arrive in Jerusalem tomorrow night," his mouth is not moving.
When Ben-Hur is summoned to Arrius's quarters aboard the ship, the Consul's personal belongings in the background appear and disappear between shots.
In the overhead view of the second turn as the chariots are taking their parade lap around the race course heading toward the starting line, there should have been hoof and wheel tracks from when the chariots made their entry onto the race course. All we see are the tracks of the horses leading the parade.
A stunt double for Judah during the race can be noticed by his wavy hair.
An establishing shot of Jerusalem in the opening sequence shows a hooded Ben-Hur, long before he is born. The scene appears again later in the film as Judah Ben-Hur returns to Jerusalem from Rome.
A pretty good breeze is blowing the sheik's robe around when he comes to visit Judah just before the race starts, but the wind and his garments are abruptly still in the second slightly tighter shot.
During the race, just before the first chariot goes down, the left wheel of that chariot is removed by Messala's chariot, but in the next shot you can view both wheels intact before it goes down.
After Judah Ben-Hur and Messala are reunited and Messala throws his spear into the cross-beams the body of the spear is shown wiggling vertically. After the next edit, it is seen wiggling horizontally.
During the ship battle, a slave is released from below and is missing his left hand. About ten seconds later, he is seen running through the ship with his left hand still attached.
After Judah denounces Rome and Esther declares that it is as if he has become Messalla, he turns to face her, in anger, but in the next frame, instead of facing her directly, he it looking at her over his left shoulder; he should be facing her or, at best, have his right shoulder facing her and looking over it.
When Arrius orders rest after having the rowers go to ramming speed, the order is given to raise oars, at the order to rest all of the rowers drop their oars, you hear them splash as they are dropped. But the oars do not change their angle to the rowers as they should if the ship were still moving through the water, they stay perpendicular to the side of the ship as if the ship were stationary.
When Juda breaks into Messala's office there is a military standard leaning against the wall in the corner. The Roman army venerated standards. Any standard not on campaign would have been prominently displayed in front of the commanders headquarters with a guard of honor.
Pontius Pilate wears a purple toga at the chariot race. Purple togas were the prerogative of the emperor and the consuls only.
In the confrontation scene between Judah and Messala when Judah demands that Messala release his mother and sister, Heston walks out of the room and the camera clearly sees that he is wearing brown hush puppies or ankle boots, definitely not period-accurate footwear.
When Ben-Hur and Arrius are shipwrecked after the battle on the sea they are seen drifting on a piece of wreckage together. We see the waves rolling past them yet they stay in one place.
At sea, away from the shore, waves normally roll past floating objects.
During the chariot race, shadow lengths/directions clearly show that passage of time (filming) inconsistent with length of "actual" race.
When the audience first sees Ben-Hur and Messala together and they both throw a spear at the wall, the sound of Ben-Hur's voice does not match up with his lips.
On the way to the galleys, a prisoner on the march dies and is cut loose from the rest. When he is pushed down the sand dune, you can see his arms pulling himself down.
After announcing Ben-Hur's arrival at Messala's quarters, the position of the centurion's hand on his sword changes position between shots.
When Messala assumes command of the garrison, outgoing commander Sextus is seen in the doorway as they are going into the barracks, yet when Messala speaks to Drusus about finally taking command, in the closeup shot Sextus is not in the doorway.
Just before the Roman galley is rammed, the condemned men behind Ben-Hur are clearly dummies.
Pilate (Frank Thring) announces a charioteer from Carthage in the race. Carthage was completely destroyed by Rome in 129 BC.
Valerius Gratus rides into Jerusalem wearing the armor of a Roman general. Generals in the Roman army were exclusively of senatorial rank. Gratus was of Equestrian rank and exercised no military command. His position as Prefect of Judea was administrative only.
Valerius Gratus and Pontius Pilate are referred to in the film as governors of Judea. At the time the film takes place, Judea was not a senatorial province and thus did not have a governor. Gratus and Pilate were prefects who reported to the Roman governor of the province of Syria.
The film implies that Jerusalem was the center of Roman administration in Judea. The Roman prefects who governed Judea made their headquarters in Caesarea Maritima, a much larger city than Jerusalem. Their visits to Jerusalem were infrequent.
When Bun Hur is about to be thrown over the chariot there is a blood spot on his upper arm. After he manages to pull himself back over the chariot it is gone.
Ben-Hur presents Pilate with Arrius's ring, to be returned to Rome. Pilate moves so that he is always facing the camera as the angle reverses.
Early in the scene when Messala enters Jerusalem, a high-altitude shot of the street shows a blanket used to shade a rooftop on the left. A very large studio prop tag on the front of the blanket is clearly visible.
Ben-Hur is whipped constantly as he marches to the galleys, and presumably is whipped during his three years of service as a rower; obviously his back should be as scarred as that of the insubordinate slave. However, when we see him from the back in the raft with Arrius, the only marks he has are those of the lash with which Arrius scourged him.
The four horses drawing Judah Ben Hur's chariot noticeably change color from 'solid white' to 'grey and white' several times.
When Judah first picks up Tirzah in the cave to take her to Jesus, her head is cradled in his right arm. When he turns to walk out, her head is in his left arm.
When Esther and Tirzah and Miriam seek shelter during the storm, Miriam appears to say something just before it is revealed that she & Tirzah are cured, but no words or sounds come from her mouth.
When the chariots are first being backed into the starting area, each chariot has just 3 horses each. Yet when the race starts, both chariots have 4 horses each.
