Continuity mistake: Kate arrives in front of the newspaper. Directly behind her a guy a bit on the chubby side is arriving as well. But he already was in the crowd shown before, looking at the dummy. (00:11:40)
Single Point of Failure - S1-E2
Revealing mistake: Walter accesses code on the sick girl's laptop to trace the source of the virus - aside from the fact that the code comes straight up a fraction of a second after his hands even touch the keyboard, the code displayed in the black window is for a set of traffic lights, with lines like "Walk/Dont_Walk" and "Green_Arrow/Yellow_Slow." (00:08:10)
Heart of Archness: Part III - S3-E3
Continuity mistake: On the way to the helicopter, Archer stops the group to ask about the lacrosse game. Archer has the pirate held at gun point and the two are standing mere inches from each other, but when Archer says to Lana she is his only friend, the pirate is nowhere in sight.
Factual error: In the scene, Floki walks towards a small waterfall today known as Kvernufoss. Floki is supposed to be the only inhabitant if not the entire Iceland, at least the region, as we are shown no sign of civilisation whatsoever, and as historical record tell us about Iceland in the early 800s (as the events of Vikings seem to take place). But a well beaten footpath is visible, leading to the waterfall at the end of the canyon. That path is an oft-travelled path tourists follow nowadays to reach Kvernufoss, a well-known site in the area. A path like that in Floki's time would simply not have existed (there is nothing in that canyon but that waterfall, no reason to go there if not for sightseeing) and represents a (tiny) intrusion of our modern world in a show set in the middle age Iceland.

Beauty and the Obese: Part 1 - S1-E1
Continuity mistake: Once the episode cuts to the inside of the Tender Loin club, a stripper dressed in blue and yellow is on the table with a very large group of men sitting around her. Once the kid comes in with the fake I.D. and is shown around by the manager, suddenly the crowd around the stripper's table is much smaller. (00:01:54)
Visible crew/equipment: As Michael and Robin go to get into KITT on the firing range, the filming crew and equipment are reflected on the light cover on the back end of the car.
Beyond the Farthest Star - S1-E1
Other mistake: When showing Scotty on the bridge, some of the frames show more of his body than others. In those frames, you can see that he lacks legs.
Visible crew/equipment: After Raines shares details with Kellett about Semien's crew, when it cuts to Semien waking everyone up, just as he announces his contact with Belgian Federal Police, there's a visible T-mark taped to the floor behind Andre's cot. (00:24:25)
Origin of Iron Man: Part 1 - S1-E11
Continuity mistake: When Rhodey, Julia and Wanda are watching Iron Man heading to the volcano on the monitor, Julia is standing with her feet pressed together and pointed at the equipment in front of her. When the shot changes, her feet are now several inches apart and pointed towards Rhodey on her left. (00:01:18)
Innervisions - S1-E7
Continuity mistake: When Silver Surfer is heading towards the temple to turn off the Dreamweaver, Beta Ray Bill throws his hammer at his back, which knocks Silver Surfer off his board and into the ground. When Silver Surfer rises out of the hole in the ground, he does so perched upon his board, even though it should be on the ground behind him.
Shelter from the Storm - S3-E18
Continuity mistake: When Winn and Brainy hug, Winn starts the hug with one arm high and one lower, towards Brainy's waist. The shot cuts and both his arms are up and in the centre of his body.
Visible crew/equipment: You can see the camera in the backseat as they pull into the gas station.
Behold the Negative Zone - S1-E12
Factual error: When the heroes fly by the World Trade Center after Annihilus and Blastaar have begun battling each other, the 1 WTC building is missing its spire, and both buildings are incorrectly depicted as being conjoined by what appears to be a multi-level walkway. (00:18:13)
Continuity mistake: When Park Eun-hee is talking into a video camera there are some on-screen icons for the camera: zoom, battery level, etc. Initially there are two guide lines on the zoom level bar. When the view changes then switches back a few seconds later, there is only one guide line.
What Price Gloria? - October 16, 1961 - S2-E4
Continuity mistake: When Sam goes out of the window to save Gloria, part of the ledge breaks off, but in the near shots it is broken off almost to the corner near Gloria, while in the shots from below most of the ledge is still intact. (00:35:45)
Continuity mistake: Ashley Barrett is first seen behind Homelander, but then in the next shot she immediately jumps in front of him. (00:19:32)
Continuity mistake: When Blob lifts up Angel, he does so by his right shoulder. When the shot changes, he is now holding him up by his left shoulder. (00:13:23)
Visible crew/equipment: During the shooting, a crew member holding a camera is visible in the upper right side of the screen. (00:22:39)
Visible crew/equipment: During the final battle between Duncan and Luther, you can see a crew member holding a boom microphone pole standing on the stack of hay bales in one of the shots. (00:44:10)
The Book of Occupation: Chapter Two - S3-E2
Continuity mistake: The first time Black Lightning is approached by the female character with the necklace, it shows that the necklace with the charm is sitting on the side of her neck. Then a few seconds later, the necklace with the charm is perfectly placed in the middle of her neck. (00:09:39)
