Character mistake: When Donnie (spotter) is giving Swagger ranges to fire, he doesn't tell Swagger what hold to use.
Character mistake: The reporter refers to a "box of ashes" being buried in Westlake's grave, whereas in the first film, all that was buried there was "an ear", which was all they could find of his body.
Character mistake: When the posse is heading out in the morning, one guy says that it's heading north and they start riding in the direction he's pointing. However it's supposed to be first thing in the morning, and you can see the shadows of the horses cast to the left of screen while they are riding towards the camera. The sun rises in the east, which would be right of screen with the shadows cast towards the west. Since they are riding towards camera, this puts them heading south.
Character mistake: Alan Alda says that his personal security code is the street address that he lived on at Steinway Boulevard when he was a kid growing up in Astoria, NY. The name of the street in Astoria is Steinway Street. (00:19:50)
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: 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: 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: Upon arriving to the house they say Zoe's mother committed suicide when she was 10 but later on before going back to the house to expose her step mom Sam says her mom committed suicide when she was 8. (00:16:56 - 01:17:46)
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: 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: 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: 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: It's merely training, but her opponents are hostile and want to exclude her from playing, so it's funny then that they don't call Kim out for her actions being egregious fouls; she brings the ball trapping it between her feet in multiple cartwheels (you can't just hold the ball between your feet for prolonged amount of times and 'carry' it). You could also say she kicks the ball at an opponent's face on purpose, which is equally unsporting. (00:24:00)
Character mistake: Toward the end of the film, Detective Davis orders Captain McKenna to put his badge on the table. New York City police always refer to their "shields", not badges.
Character mistake: Violet is in the Army, but does not have her hair up properly in uniform.
Character mistake: In the bathroom scene with the fat man tied up, Kevin answers his phone upside down.
Character mistake: When giving Eggsy a tour, Galahad tells him that Oxfords are any formal shoe with open lacing. This is incorrect as Oxfords have closed lacing.
Character mistake: As Lex is studying the recording of when Superman's body vanishes, he says "A 19 second black out at 3:47 AM." But the clock on the video shows it goes from 3:47:05 when the blackout starts, to 3:47:26. The blackout was 21 seconds, not 19. (00:45:55)
Character mistake: Max back in London is referred to as Group Captain, but his RAF Rank shows him as a Squadron Leader.
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".
