Character mistake: In the bathroom scene with the fat man tied up, Kevin answers his phone upside down.

Character mistake: When the MC introduces Lucius and his team during the naval battle, he says, "Today, we relive the battle of Salamis; the Trojans vs the Persians." The battle did involve the Persian empire, but not against "Trojans", but rather the Greeks.

Character mistake: At the party, Fred is supposed to make a bbq, feeding about 50 people. But once he's got the fire going, he puts two lonely pieces of hamburger meat on top, to cook - only two.

Character mistake: When Donnie (spotter) is giving Swagger ranges to fire, he doesn't tell Swagger what hold to use.

Character mistake: When the American hands over the wills to Ian Fleming he calls him Lieutenant Commander, but when Fleming turns up at the camp he has gold braid on his cap - only commanders and above wear gold braid. Also they kept calling the RAF guy Flight Sargent but he didn't have a crown above his stripes.

Character mistake: At the beginning of the movie Marty is turning on a huge guitar amplifier. The two switches for the filaments are misspelled. They are shown as "filiment." (00:03:25)

Character mistake: When Rommel leaves his French headquarters for Germany on June 5th for his wife's birthday on the next day, he erroneously states that date as 6th of July (pronounced yoo-lee), not June (pronounced yoo-nee). (00:29:30)

Character mistake: The newspaper headline quotes "parent's" death in a murder-suicide story. Should be "parents' deaths" as both have died. (We can forgive the newspaper not picking up on the fact they were killed by a government assassin).

Character mistake: The protagonist says "You know, Croesus once said 'Count no man happy until the end is known'" but it's not Croesus uttering that line. According to Herodotus, Solon says it to King Croesus. (00:03:00)

Character mistake: In her first walk through the city with Dr. Ido, after feeding the dog her sandwich, Alita takes a flyer and reads it. Between the lines that read "Wanted" and "Murder" there is a line in Spanish that says "Querido para el asesinato." It should say "Querido por el asesinato".

Character mistake: When the alarms go off in the police station indicating the code 187 all the police officers are confused as to what is going on since they know nothing of MDKs. Zack Lamb should have already known what the code meant, yet he never says anything and just waits for everyone to figure it out.
Suggested correction: I took it as he went into almost shock that after so many years a murder had actually taken place. He says, "I don't believe it," indicating he knew what the code meant but then he kind of froze until Phoenix's name was mentioned.
Suggested correction: Zack Lamb is quite old and it's possible he simply forgot what the code meant. He was a pilot too, not a street cop.
When Stallone first meets Lamb after being thawed in the future, he tells Spartan he was "grounded" after the events in the opening scene so had not been a pilot for 36 years.

Character mistake: On the tour boat in London, the voice on the loudspeaker says 'if you look to your right, you will see the Tower of London'. Except it's on the left, given the direction the boat is travelling. (00:53:00)

Character mistake: When Dutch is at the main gate to report for duty, he addresses an Airman as Sergeant. In the time period of this movie, an airman wearing three stripes would be an Airman 1st class.

Character mistake: While discussing his squad providing air support for the Marines on the ground, Lt. Cmdr. Cevoli refers to the men as "soldiers." Marines are not called "soldiers" because they are not in the Army. It is common for a layperson to make this error but nobody in the U.S. Navy would do this.

Character mistake: Lt Col Van Patten's ribbons are out of order.

Character mistake: After crashing their car into the bar the Tender Trio attempt to flee on foot but Clipper twists his ankle. Goose says "Goose f***ed up his ankle" accidentally referring to himself but obviously it's Clipper that twisted his ankle. (00:14:59)

Character mistake: Dan is supposedly such an expert in Pakistan, but he hands Ammar the cigarette pack with his left hand (unclean to Muslims, and therefore not much of a gesture of hospitality).

Character mistake: When the Smiths first enter the store Home Made, the camera pans around and faces the store's large display picture which reads, "The true measure of a home lies in it's kitchen," but the word "it's" should be "its."

Character mistake: There was no chance of Will and Lori knowing what's happening with Mark in the house. Neither him nor anyone else called them. So what made them rush home with van, after they've been casually driving in their previous scene?

Character mistake: Declan tells Ethan that 162 (meters) is "pushing minimum height for a (BASE) jump." This is not the case. It's not uncommon for jumps to be made from sub-100m heights. In fact the lowest BASE jump was debatably made from the hand of the Christ the Redeemer in Rio at 29 meters. However it must be said that jumping between buildings, like in the movie, is extremely dangerous and carries even more risk than just normal BASE jumping. (01:22:20)
