Revealing mistake: At the very beginning of the episode, we see a hydrocharge being fired which causes an explosion in the sea. Then just a few shots later, another hydrocharge is fired and we see the same explosion - this is due to footage of one explosion being used twice.
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.
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)
Revealing mistake: During the "power outage" when Brian is out on the street during the day, all the stop lights and cross walks are on - you can also see the lighting is on in the windows of office buildings.
Revealing mistake: Dr. Shannon identifies the skeleton as being a middle-aged male, but the skull is female. A male skull has a more pronounced ridge over the eye orbits, a sloping forehead, a longer mastoid process, and the skull widens at the back, unlike a female's that is more parallel.
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: The bare, non-furry, forearms of the actor playing Anto are exposed when he is entertaining the gorilla soldiers.

Revealing mistake: When Nomi is on her bike, in a wide shot, she is portrayed by a stunt woman.
Revealing mistake: When Caleb arrives, as he's talking to Billaba and Grey, his Padawan braid clips through his cloak as it sways back and forth. (00:02:05)
Revealing mistake: When Martin uses telepathy to tell George's girlfriend how to open the window, the two wires attached to the bows on the dog's floppy ears are visible. (00:05:05)
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.
The Cavern - S1-E10
Revealing mistake: When Jonathan and Nicky are running out of The Cavern during the rockfall a cabinet is knocked over by the vibration, but you can see that it is pushed over by someone with a stick.
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.
Revealing mistake: After Krystal goes to the bathroom, Sarah's phone is not in call mode.
Revealing mistake: Jamie prepares to split a giant heavy log in two, with her bionic arm, so that it will fit into her fireplace. Just as her arm comes down, you can see the middle seam where the log was pre-cut for the shot, so that it easily breaks in two. (00:00:30)
Revealing mistake: June goes to an airstrip to fly to Canada, but all the abandoned aircraft on the field are ex Canadian Air Force, meaning it was probably filmed in Canada.
An Insidious Trap! The Flying Fleet - S1-E3
Revealing mistake: When Hayato attacks Bullface with the Liger missiles, the explosion does not follow at all the outline of the ground, it just cuts away in a straight line superimposed in the wrong spot. (00:18:15)
Revealing mistake: During Kendrix's morphing sequence you can see that the editor did a poor job photoshopping the Ranger helmet and you can still see the white edges of whatever photo they used. It should be tight to the Ranger's helmet and costume like the rest.
