Visible crew/equipment: At the very end of the episode, right after he tells Jesse how he used the red phosphorus to kill the gunmen, Walt leans down to vomit. You can see his microphone transmitter under his shirt. (00:54:20)
Other mistake: Carrie the assistant brings Lisbon and Jane to Stutzer's office. She swipes her card to open the door. However, she does this upside down, swiping the bar-code instead of the black magnetic strip, on which she is holding. (00:09:30)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: When Tony says he has to stop the train from hitting the building’s power generators, the camera zooms in on a train car at the entrance of Stark Tower by the tracks that has the generators on it, and there are two Stark International employees standing on the balcony beside it dressed fully in white. Only a couple seconds later, Tony flies down there to cut off the train, and suddenly the two guys have vanished. (00:18:00)
Triumvirate of Terror! - S3-E8
Continuity mistake: When Joker zaps Wonder Woman and her mother, they are both standing in front of their thrones and fall forwards. But when Wonder Woman stands back up, her mother, still unconscious, is suddenly off to the side and behind the thrones. (00:11:35)
Power Hungry - S1-E5
Visible crew/equipment: When they're transporting Joseph Meegar out of the building and into the ambulance, you can see the reflection of the boom mike on the open car door, (the car Charlie is putting Mr. Fischer into). (00:41:00)
Continuity mistake: When Mary offers Walter the fast food bag of chicken soup, her hand disappears and reappears on the top of the bag. (00:34:40)
Thorpe Park - S1-E3
Factual error: The same number plate can be seen on two different vehicles in this episode. The registration M483LTH can be seen on the hearse and then on Simon's car when parking. No two vehicles in the UK will ever share a number plate. (00:11:10 - 00:12:30)
Other mistake: In one shot after the droid fight in Gha Nachkt's ship, at one point when you see R3-S6 (Goldie), his eye is reversed. (00:12:42)
Continuity mistake: After the POV shot of Domino's sniper scope pulls up, a billboard with Magneto on it is on the right side of the screen, over a building with a red roof. When the shot changes, Domino is perched at the bottom left of the same billboard. If she was perched there, then the billboard could not have been to her right when she raised the sniper scope. Additionally, the roof of the building is now white. It's not a separate billboard on a different building either, because the waterfront and docks are the same angle respective to the first shot of the billboard and the shot of Domino loading the magazine into the gun. (00:18:19 - 00:18:42)
Continuity mistake: 4.03 - The 15 Minutes Job. Parker gives the target her number on the napkin, tells the guy to call her and takes a drink. The way she holds the glass changes immediately.
Visible crew/equipment: When Jimmy Smits and Dave Navarro are talking to the shopkeeper, a microphone wire can be plainly seen under Navarro's wife-beater. (00:14:25)
The Darkest Hour: Part Two - S4-E2
Revealing mistake: At the very beginning of the episode, as the knights are about to send Merlin to Camelot with Lancelot, the knights walk towards the camera. As they do, there's a patch of green screen the special effects department must have forgotten to remove between Sir Elyan and Sir Percival. (00:02:10)
Glory Days - S8-E3
Continuity mistake: Towards the end of the episode, during the final shootout, Murdoch ambushes an armed bad guy in the attic and jumps through the wooden wall with him. As they fall down, Murdoch's trademark hat spectacularly flies off his head, but in the next overhead cut - showing him and the bad guy lying on the ground - the hat is on his head again.
Combat Jack - S1-E4
Visible crew/equipment: Multiple times during the "Fixin' To Die" song, a reflector screen can be seen in the glasses of Ray. (00:37:30)
Seattle, WA - S6-E6
Continuity mistake: While at Easy Street Records they make a plate of corn beef hash with three eggs sunny side up. When the dish is finished the eggs are placed over easy on top of the hash, but when served the eggs are sunny side up. (00:44:00 - 00:45:00)
