Continuity mistake: When Eden confronts Kinsey by the lockers, as the angle changes so does Kinsey's arm. In some shots, she has her arms crossed and the locker door is closed, in some shots she has one arm up, holding the (open) locker door.
Other mistake: After they arrive in Marina Bay the pink ranger is wearing the red ranger's jacket.
Bubble, Bubble, Toil and Trouble - S2-E22
Continuity mistake: Cleo, Rikki and Emma are sitting together in their school campus grounds. Cleo is sitting upright in the wide shot but she's leaning to her left in the close-up. (00:10:10)
Continuity mistake: An employee is asked to leave the computer lab, he actually exits it twice. (00:11:15)
Episode #1.1 - S1-E1
Visible crew/equipment: When we see Dinah, Lloyd and Harvey walking to school the first time if you watch the top of the screen you can see the boom mic drop down into the shot a few times. (00:04:42)
Other mistake: When Teela is at Snake Mountain, she overhears TrapJaw saying how Skeletor's electrical creature will control all of the machines at the palace. When Teela returns to He-Man, she says that the creature Skeletor created is called Byte. There's no way for Teela to know the name of the creature, since TrapJaw never referred to it by name. (00:14:24 - 00:15:20)
Factual error: In Massachusetts, Atticus, Leti and George are attacked by the local sheriff and his deputies, who are patrolling the county roads. In Massachusetts, sheriffs run the county jails, but they do not (and did not) handle routine policing, which is the responsibility only of municipal police departments.
Continuity mistake: When Will Parry visits his grandparents, the grandmother is sitting on the sofa next to Will's grandfather. The grandmother's position keeps changing from sitting right next to him to being further apart.
Continuity mistake: When Marshall first finds Trip's letter, he holds it from the left side. In the close-up, he's holding it from the right side. (00:02:10)
Continuity mistake: The three friends finally meet in person after all the texting. Karube brings a cigarette to his mouth when Chota asks "Where to?", but in the next shot his hand is lower. (00:07:15)
Gortimer vs. The Mobile of Misfortune - S1-E3
Visible crew/equipment: When Stanley is riding the kart in the race, the shadow of the camera equipment is briefly visible bottom right, just before the kart starts to fall apart.
Episode #1.2 - S1-E2
Continuity mistake: In the flashback to Andong's restaurant, Ms. Andong begins pouring some gin from a glass bottle into the glass of the guy sitting next to her. When the camera changes angles, the bottle is suddenly upright and not being poured. (00:19:47)
Flash Gordon and the Planet of Death - S1-E1
Revealing mistake: In the flashback of the scientists' fate on the planet of Death, the sole survivor manages to run away and avoid the ray of "Belfagore" (which is just a big flashlight). Problem is, he does not; before hitting Bending behind him, the beam fully lit up his back, but he suffers no adverse consequences, no dropping dead for Jefvus. (00:06:40)
Continuity mistake: When Elizabeth starts weeping, her bodysuit is torn above her left breast with a single tear. Post-credits Meliodas asks her to join him; now that torn spot is split in two - the first time the bit of fabric that separates the two spaces was already severed. (00:17:40 - 00:22:30)
Factual error: When Alina stands outside of the door to the banquet hall, waiting to demonstrate her power to the king and queen, there is a modern electronic occupancy sensor on the wall behind her.
Plot hole: Loki states while on trial that The Avengers should be on trial for traveling through time to change the timeline. How did he know they came back through time?
Suggested correction: He recognized that there were two Tony Starks in the lobby by the smell of their colognes, and combined with all the other unusual shenanigans going on, he correctly deduced the Avengers travelled through time, though he incorrectly thought it was to prevent his ascendancy.
How exactly do you distinguish the smell of cologne as belonging to two separate people? But besides that, it's pretty wild to jump to a conclusion about time travel when it could be that someone else happens to be wearing Axe.
I'm sure he simply recognized his voice.
Factual error: A man enters a bank and begins firing his Glock 9mm pistol. A few of the men he shoots, jump up in the air after the rounds impact their bodies. Bullets hitting a body will never make it jump, or fly in the air. (00:00:01 - 00:01:46)
Revealing mistake: Whenever Isis has to do jumps you can tell it's not her but a stunt double.
Other mistake: You don't have to look further than the name; the title of the series is "Knight's and Magic" instead of "Knights and Magic".
Firefly, Light My Fire - S1-E1
Revealing mistake: Courage winces and reacts before the stereo-zapper is fired.
