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)
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)
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)
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: 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)
