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.
Revealing mistake: After the Shadow Duelist has activated the effect of Terrorking Archfiend and the flame has landed on the ball labelled 2, just as he says, "Mirror Gate is shattered", the card shown on his duel disk is misshapen, where two corners of the card are curved, instead of being straight. (00:16:23)
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.
We Will All Be Judged by the Courage of Our Hearts - S1-E8
Revealing mistake: When Nomi is on her bike, in a wide shot, she is portrayed by a stunt woman.
Revealing mistake: The effects of the wind blowing at Gale Frazer's Ranch are obviously being produced by a wind machine as only targeted areas of the ranch set are having wind blown at them.
Revealing mistake: The bare, non-furry, forearms of the actor playing Anto are exposed when he is entertaining the gorilla soldiers.
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: Every time "red alert" is on the screen, it's easy to see the screen is an overlay with "red alert" cut into it.
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)
Revealing mistake: After Krystal goes to the bathroom, Sarah's phone is not in call mode.
Revealing mistake: Batwoman gets shot in the alley; the bullets create bad looking CGI sparks each time they hit her suit. When she gets back to the cave and sits down as Luke scolds her, you can see her suit bends and folds at the breastplate all rubber-like, making even more unlikely the fact that bullets would create sparks on impact (for what is worth, in the following episode there's a close-up of a bullet hitting the breastplate of the suit and there is no trace of sparks and not the slightest give from the material). (00:02:00 - 00:03:55)
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: 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.
Revealing mistake: When Gamora is warning Silver Surfer to think about what he is saying, the gallery of characters behind her are the exact same on both mezzanines.
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: 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.
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)
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: While Matt is lying in his hospital bed, he hangs up on a call with Emma. You can see his left foot moving. He's not supposed to be able to feel or move his lower body.
