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)
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)
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)
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.
Continuity mistake: When Magneto uses his powers to create a hole in the metal wall, the edges of the wall surrounding the hole are smooth. When the shot changes, the edges suddenly look crumpled. (00:17:16)
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)
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.
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)
