Us vs. Them - S2-E2
Factual error: We see Liam's driver's license. It says he's from Rhode Island, but the license looks nothing like RI's. It's issued by the State Motor Vehicle Commission, but RI does not have an MVC (only New Jersey does). And the expiration date is always the same as the holder's birthday, but here we see it's 2 days after his birthday.
Deliberate mistake: Season 2, episode 6 "Identity Crisis": When Bizarro starts decaying into the parody form of Superman, his costume goes with it; the blue fades, and even the 'S' insignia changes. Strange that superhero garments change right alongside their wearers when they suffer from an unstable genetic effect. Were the clothes cloned right onto his body, instead of sewn?
The Book of Occupation: Chapter Five: Requiem for Tavon - S3-E5
Visible crew/equipment: Right before Anissa and Tavon are attacked by Khalil, the shadow of a camera can be seen on the ground in the bottom right corner of the screen as they approach the path.
Coming Home - S1-E13
Plot hole: Amuro flies the Core Fighter to the refugee camp. Taking a plane to get just across a hill is already kinda a headshaker, especially with White Base being short on resources, including fuel that is an issue in this very episode.Anyway, he lands it in the middle of the camp, and the people there tell him to please hide it. Later in the episode, we see that Amuro indeed hid it, in the middle of some woods, covering it perfectly in branches and other things. How in the world did he get the fighter there and on his own did all the camouflage work on the huge thing, is a prodigy of off-camera work.
Pathfinder - S2-E4
Factual error: Ed and Gordo are both flying NASA T-38 Talon aircraft from Houston to the Cape. NASA is a civilian space agency, and all of its planes are registered as civilian aircraft. But Ed's T-38 is shown in one shot as having US Air Force registration.
Factual error: Henry states that the car bumper of an 2007 'XJ' is a certain height off the ground and led to a particular injury to a dead person. He claims he knows this because he is a Jaguar enthusiast. He then points to a photograph of the 'New York Kids' in a pre-2002 Jaguar XKR as 'circumstantial evidence' that it was this car that caused the injury. A Jaguar enthusiast would never mistake an XKR for an XJ.
The Mind of Simon Foster - S3-E23
Continuity mistake: When the pawnbroker closes his metal gate, he's facing the wire mesh. When the shot cuts, he's instantly facing away from it. (00:10:15)
Continuity mistake: David and Kathy exit to the outside of the building, closing the inside door and the outer door. When Sheriff Carver exits to the outside, the inner door is not closed, but open as he steps out.
Revealing mistake: Mr Knight shoots Suzie Boreton - after the muzzle flashes and sounds stop the bolt of his MK14 EBR continues to move back and forth as if it's still firing. (00:30:30)
Crystal Blue Persuasion - S3-E15
Factual error: When Frank, Olga and he rest of the Back Step Team meet Commander (a Navy O-5 Rank) William Streck, he is dressed in a U.S. Air Force Uniform with the rank of Colonel (O-6).
Continuity mistake: When Captain Bragg orders her troops to move in on the people in the square, GS-8 is standing behind her, despite the droid having fled the scene just two shots earlier after Senator Singh's arrest. (00:02:58)
Emergency Marineville - S1-E11
Continuity mistake: When the second group of Spearhead jets take off from Marineville there are only two jets, but in the next shot you can see three jets, and in the next shot there are two again.
Audio problem: While Pickles is sniffing the ground, she asks Bob "Did you know vomit tastes bad?", but her lips don't match what she is saying.
San Junipero - S3-E4
Continuity mistake: Near the end, Yorkie gets into a red left-side drive convertible, then is seen driving on highway in the same car but with right side drive. Following scenes are of a left-side drive car. (00:58:00)
Continuity mistake: When Molly is in space, alone, a man she knew is on The Other Side of a door that has a circular window in it. The man uses his finger to draw the words "HELP ME." When we first see the words, they are legible and about a third of the way below the top of the window, but the next time the words are much higher up and hard to read, and the third time they are now back to the original place.
A Single Piece Was Lost - S1-E10
Visible crew/equipment: When the Gruenaks attack the Scientist a puppeteer is visible to the right of one of the Gruenaks, just before it grabs the bird cage and throws it onto the Scientist's head. (00:28:18)
Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
There Is No Normal Anymore - S1-E2
Continuity mistake: The beautiful blonde visitor takes a picture of herself on Tyler's phone. However, we get a perfect view of her as she concentrates to take the snap (looking very serious and studious, barely showing her teeth), but when we see the picture she is wearing a classic toothy smile right across her face. (00:23:00)
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
Triumvirate of Terror! - S3-E8
Continuity mistake: At the diner when Superman, Batman, and Wonder Woman are discussing the Superhero Memorial Time Capsule, Wonder Woman's cup is next to her arm. Then a few shots later, without her touching it, the cup is suddenly much closer to the edge of the table. (00:09:10)
