Revealing mistake: When Major Popov aims the rocket launcher at the Venus probe, there is no rocket in the launcher- it is just an empty tube.
The Defection of Hawkeye - S1-E8
Revealing mistake: When Hawkeye is saying "Hey, what's shaking, gang?", the screen is shaking from left to right, likely indicating a composite shot. (00:08:54)
Revealing mistake: Multiple times when we see the speedometer of the minivan, the RPMs aren't moving. The car's shifter is also noticeably in park. This is obvious as its higher, whereas if were in drive, it would be lower. Even during the most intense moments, the RPMs never change. The car is obviously being towed by a camera vehicle.
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.
Split Second - S2-E2
Revealing mistake: Shortly after Kiera drives the van past the train tracks, we see a few different shots of Travis and Carlos fighting. In a couple of quick shots, Travis' stunt double can be seen. (00:13:00)
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: The wires holding the small satellite the two alien men are 'channeling' across the lake are visible although it's supposed to be floating.
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)
Man to Man, Beast to Beast - S1-E6
Revealing mistake: When Hulk uppercuts Sasquatch into the ice wall, if you look closely you can see that Hulk's fist doesn't even make contact with Sasquatch.
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)
Revealing mistake: When Ms. Haman is shot by the soldiers, the moment that the gunshot that hits her is heard, and she is shot, there is already a massive, thick blood stain on her dress from where she is bleeding from. No gunshot wound on the planet can create an amount of blood that massive or thick in an instant. The blood stain was likely applied to her dress before filming the shot. (01:17:52)
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)
