Revealing mistake: Whenever the newspaper Josh is shown at the beginning appears, the news story consists of a paragraph that repeats itself.
Revealing mistake: Not only is the stunt double's face visible in several shots during the apartment fight scene, the man is also noticeably taller and heavier than Robert Wagner, and is wearing a really bad wig.
The Defection of Hawkeye - S1-E8
Revealing mistake: When Spider-Woman is blasting at Whirlwind and Blizzard, one shot pans to the left from Whirlwind to Blizzard, and you can see the edge of an animation cel. (00:05:03)
Lightspeed - S5-E8
Revealing mistake: When the HIVE Five exit the museum and are intercepted by Kid Flash, Mammoth loses both his pants and the artifacts he has before KF whizzes past him. It's best seen in slow motion; at normal speed this mistake is hard to catch.
Not Kansas - S3-E21
Revealing mistake: As the guy fires the machine gun at Guardian, there's a closeup of bullet casings falling to the ground, but they're not just empty casings, they're fired blank rounds.
Slouching Towards Bethlehem - S2-E8
Revealing mistake: When Kenya is being held at gunpoint the pistol pointed at her has a visible seam running up the grip and the back of the slide. It's a plastic prop.
Revealing mistake: When Travis dumps out the heads of the gangs leaders from the case, it is painfully obvious that they are computer generated.
Chapter 7: In the Name of Honor - S1-E7
Revealing mistake: When the big battle starts, Boba and Mando appear using their jet packs. As Boba lands with one foot forwards, sand is thrown up into the air, but the sand is a special effect coming from about a metre in front of Boba, not from the foot itself. The result is very unconvincing.
Revealing mistake: After Krystal goes to the bathroom, Sarah's phone is not in call mode.
Fence + Suitcase + Americium-241 - S3-E12
Revealing mistake: When MacGyver cuts the green wire under the bomb, the wire is not tied up at both ends. (00:25:45)
Revealing mistake: After Max the dog breaks free from the cage and then bites through Callahan's chains, the two head to the metal barred window and Max begins pulling on one of the bars with his teeth. Which are obviously rubber, as they 'bend' slightly as the dog is pulling.
When in Rome - S1-E3
Revealing mistake: Will and Frankie are in a boat. In the first wide shot the boat is going rather slowly, in the next shot they are speeding many times faster, and the shot is erratic, showing that the action was speeded up. (00:02:05)
Winds of War - S1-E8
Revealing mistake: When the widow is bandaging the fighter pilot, the part of bandage she is wrapping appears and disappears during the animation - when her hand movies, instead of adding new layers of bandage, the army causes the green sleeve of the space suit to flash back in view. (00:20:10)
Helping Hands, Iron Fist - S1-E4
Revealing mistake: When Iron Man appears on the screen in the Hulkbuster armor, if you look at the background behind him, there is a closed door behind him to his right and a control panel directly behind him, which means he appeared from out of nowhere.
The Killer - S1-E1
Revealing mistake: When Drake puts the bomb against the ceiling, the 'concrete' wobbles. (00:40:00)
Revealing mistake: In the Batcave, the protagonist looks at the newspaper clipping about the death of her mother. The rightmost column has a headline "Children traumatized after ride of terror", and a sign ("by Lucy Moguire"). And yet, it begins like this; "With the population of the planet ever increasing, so does the demand on Earth's resources." It's a lazy copy and paste by the prop department, putting some global warming report as filler text. (00:27:40)
Revealing mistake: After Mr. Haengrang and Ms. Haman are shot by the Japanese soldiers, there are visible blood stains on their clothing from the wounds they would have sustained. But there are no bullet holes shown on the blooded part of their clothing, which is where the bullets would have hit. (01:17:49)
Revealing mistake: About 20 minutes in, the cops have a newspaper with the headline about the two guys they killed. They turn to page two which has a story about the next guy they are planning to kill. If you look at the picture, it is glued onto the story page. The left side is lifted. The actor must have been hired after the printing.
Revealing mistake: When everyone is supposed to be frozen, the neighbor girl standing behind the car can be seen moving her hand onto the car. This happens as Monica says "I'm not afraid of you, Wanda." (00:24:25)
