When Patton learns he has been relieved of command of the 7th Army, Willie "George" Meeks escorts Patton's aide while wearing Staff Sergeant's stripes. In a later scene when Meeks is waiting for Patton to prepare for bed, Meeks is wearing the stripes of a Sergeant.

In Smith's office, after the Knutsford speech controversy, Patton's left shoulder has no patch on it. When he goes into the hallway to meet his orderly, Meeks, the Seventh Army patch of his last command is there.

In various views of the US flag to Patton's right, during his apology for slapping the soldier, the flag is hanging straight down in the long shots but in several medium shots, it's spread out so that most of the flag is visible, even though there's no wind.

The eye-bandaged soldier's dressings change from being mostly around his eyes to being around his nose, mouth, chin and part of his neck as General Patton gets up to move on to the next soldier. Furthemore, the air/oxygen mask the soldier was wearing against his skin around his nose and mouth is now inexplicably on top of the new bandages. His hair also appears to have grown and darkened.

The head-bandaged soldier beside the eye-bandaged soldier's bed in the field hospital scene mysteriously loses his head bandage following the previous shot as General Patton gets up and moves on to the shell-shocked soldier.

Contrary to the way it's portrayed in the film, the controversy over George S. Patton's Knutsford speech was not over his having insulted the Russians (in fact, the Army quickly revised the initial transcript of his remarks to reflect that he had mentioned them). It had to do with his talk of "ruling the world" after the war - members of Congress said he had no business as a general commenting on post-war political affairs, while others objected to the notion of the US, Britain or anyone else "ruling the world."

The scene at the beginning of the Normandy breakout where Rommel, Steiger, and Jodl are arguing over whether Patton is leading the attack, or whether he is still in England preparing for the 'real' invasion could not have taken place. Erwin Rommel's staff car had been shot up by R.A.F. fighter bombers at the Normandy front on July 17, 1944 - over a week before Operation Cobra started. Rommel was badly wounded in the attack and in a French hospital at the time the scene is supposed to have taken place.

When the Heinkel He 111s are attacking, Patton pulls out his 1903 Colt General Officer's Model Pistol, firing nine rounds at the planes. The 1903 General Officer's Model holds 7 rounds in the magazine and 1 in the chamber.

When first seen, Field Marshal Rommel is identified in the explanatory subtitles as the commander of the Afrika Korps. Erwin Rommel was, at that time, commander of Field Army Afrika, which was a higher level command that included the Afrika Korps as one of its units.

Many German soldiers are shown armed with MP40 submachine guns, as common with films based during the Second World War. Like other nations to use submachine guns, the MP40 was issued only to officers that needed more than a pistol, and those soldiers whose role prevented them from using the regular issue Karabiner 98k, such as artillerymen, tankers, drivers, and so on.

During the first battle scene overseen by Patton, he uses a pair of binoculars clearly marked "JAPAN". The US Military bought binoculars from Japan up until 08 Dec 1941 and most were used by the US Navy.

Jet stream or plume above Patton and Bradley at the tank crossing in France - seen in several frames is a claimed anachronism. However, water vapor condensing from the exhaust of both piston and jet engines can cause condensation trails ("contrails"), which were a common sight over Europe.

When Patton arrives at II Corps Headquarters near the beginning of the movie, the peasant woman who follows him to the door (holding chickens in her hands) speaks Spanish ("Oiga, oiga...compre gallina.") not Arabic. In fact, this took place in formerly Spanish Morocco, so the use of Spanish as a second language would be understandable.

During the discussion with the British Leadership prior to the invasion of Sicily (where Patton advocates his army land at Syracuse), Patton and his staff are wearing the shoulder patch of the I (1st) Armored CORPS (with Roman numeral I, NOT the 1st Armored DIVISION which has an Arabic numeral 1), which Patton commanded in the US and was redesignated the Western Task Force for the North African landings. The organization reverted briefly to its original designation and insignia of I Armored Corps during the period between the Battle of El Guettar and the invasion of Sicily when this scene takes place, with Patton resuming command and passing command of II Corps to General Bradley; I Armored Corps was then redesignated the 7th Army for the Sicily Campaign with II Corps being incorporated into it. Rather than being a goof, this a highly accurate attention to detail. (Also, Patton never replaced the original I Armored Corps patch from his sheepskin jacket as seen in later scenes during the Battle of the Bulge, probably because removal of the patch would have exposed the stitch holes and compromised the leather.)

The scene, where General Fredendall jumps into his jeep after being relieved of his command of II Corps by Gen. Patton, the camera shows two GI's replacing the two star I.D. plates in the front of Patton's vehicle with a 3-star I.D. plate after he self-promoted himself in advance of receiving Senate confirmation. The next scene shows Patton and Bradley heading toward the battle front until he orders the driver to turn right to head for Carthagenian ruins. It shows that vehicle has a 2-star I.D. plate; however, this was not Patton's vehicle but Bradley's (who was still a major general), as the actor at the wheel, Carey Loftin, is listed in the credits as "General Bradley's Driver". Loftin also appears in the earlier scene at Kasserine Pass in that capacity.

As we see the local spectators during the Moroccan military parade, one little boy keeps making faces and waving into the camera in every shot.

After Patton's speech, a child is trying to steal a dead soldier's wedding ring. As he goes about this, the soldier's shoulder/arm muscles twitch visibly in reaction to the scorpions climbing on him. His head and eyelids can also be seen moving several times.

In the latrine scene where British General Montgomery is briefing U.S. General Smith, Montgomery breathes on the mirror to make a mist, then draws two maps of Sicily on it to show Smith two attack options. Afterwards, Smith erases one map for security reasons, but leaves the other one intact.

In the first battle of the film, a high angle long-shot shows a German soldier following a tank who falls forward from the shock of an explosion that happens behind him. But he falls shortly before the blast.

The extreme close-up of Patton's eyes in the opening scene shows the gauze of the false white eyebrows.

When Monty draws his plan on the mirror in the lavatory, it's obvious that it's not breath vapor, but a substance that collects in small furrows, which water vapor will not.

Bradley and Patton are both 3-star generals, but the placement on the collars is different for both men and changes frequently.

Patton is shown having read a book, "The Tank in Attack", by his adversary, Erwin Rommel. The book "Panzer greift an" was however never finished by Rommel. Most of what was to be in "The Tank in Attack" can be found in the book "The Rommel Papers", which is made from notes and diary entries by Field Marshal Rommel during the Africa campaign.

The tanks used in the major battle scene in North Africa are post-war tanks. On the German side the M48 tank (1953) was used and on the American side the M41 Walker Bulldog (1953), M46 Patton (1949) and (mostly) M47 Patton tanks (1952). The M46, M47 and M48 were all named "Patton" in recognition of his mastery of tank warfare.

Some of the U.S. vehicles in the North Africa and Sicily scenes are shown with the insignia of a white star within a circle. The circle was not added until just before the invasion of mainland Italy in September 1943.

Germany is already divided to East and West Germany in the map of Europe seen in the headquarters, and all other national borders are post WWII.

This movie makes use of the real WWII Jeeps - the MB, GPW; manufactured by Willys & Ford from 1941 - 1945 as well as the first civilian Jeep vehicle, the CJ-2A produced in 1945. The CJ came with a tailgate, side-mounted spare tire, larger headlights, an external fuel cap and many more items that its military predecessors did not include. This "goof" is common in WWII movies.

During all battle scenes the sound of distant explosions syncs precisely with the sight of them. This is of course impossible due to the discrepancy between the speeds of light and sound. This goof is made in virtually all war films as well as documentaries where sound is added after the fact.

At Messina, where the pipe band leads the British parade, the pipers are clearly not playing. Most of them do not move their fingers at all, and those that do (on the left of the screen) do not do so in accordance to the tune (Scotland the Brave) on the sound-track.

The bagpipe music starts before the pipers have inflated their bags and struck in.

When Patton receives his medal from the Moroccan minister, the minister's mouth does not move in sync with his dialogue.

When Montgomery is called for his audience with the King, the mouth of the announcer does not move in sync with his voice.

When Patton is directing traffic in the muddy field, one of the tanks that is coming toward the camera is driven by a man wearing civilian clothes and a beret.

When Generals Smith and Montgomery are discussing Sicily in the latrine, the shadow of the cameraman is seen behind Smith.

When Patton is being told he is on probation, in his room in London, a studio light is reflected in the glass of a picture frame on the wall.

As Patton is viewing the battlefield through binoculars and facing the camera, various lights/booms etc are clearly reflected in the binocular lenses.

In the war strategy for the Sicilian invasion, Patton says that the ancient Greek general, Alcibiades, knew that in order to invade the Italian peninsula, you do it via Sicily. Patton said that it was a no-brainer for "old Alcibiades." The Athenian general, however, was not interested in attacking the Italian peninsula -- he never did -- but only was to invade Sicily itself -- and he failed failed miserably. This would not have been an inspiring argument for the Allies to invade Sicily in WWII.

A map of Normandy is completely inaccurate. Rather than five beaches (Utah, Omaha, Juno, Sword and Gold), it only shows three, and only has two flags over those three beaches. There is an American flag over Omaha and Utah, a blank space over Juno, and a Union Jack over Gold and Sword.

In the opening war scene, set in North Africa, two vultures are shown in the abandoned camp. These are Griffon Vultures which are extremely rare in North Africa (but more common in Spain where the film was shot).

Visiting the Carthaginian ancient battle field in Tunisia, Patton says, "The Arab women stripped the dead soldiers of their clothing." There were no Arabs in Tunisia during the Punic wars. The line is complete fiction, obviously intended to draw parallelism between the ancient Carthaginians and Patton's troops in the first shot of the movie (who were not scavenged by Tunisian civilians in real life either).

A German soldier writing down the number of casualties is shown marking the thousands with commas, as usual in English. Later, the same soldier is shown using periods for thousands, as a German would.

Patton quotes Prussian King Friedrich the Great as saying, "L'audace, l'audace. Toujours l'audace!" Historians attribute this quote to the French revolutionary Georges Jacques Danton.

In the early scene in which Patton senses an ancient battlefield, he refers to his driver as "Sergeant", although the driver wears the chevrons of a corporal.

When the British troops parade into Messina, a sign can be seen on the wall saying "Benvenutti amici a Messina", with a spelling error (it should read "Benvenuti"). Arguably plausible, as Sicilians are said (by non-Sicilans) to be poorly educated in spelling.
