Continuity mistake: Throughout this entire season, the blue tape holding the new windscreen in place on Walt's car is constantly disappearing and reappearing. This happens throughout several episodes.
Suggested correction: The tape is only there while the adhesive sets in his continually new windshields, as he only just replaced the windshield and probably took off the tape off camera because it wouldn't add to the plot.
Box Cutter - S4-E1
Continuity mistake: When Gus is getting his shirt back on, he's doing up the first couple of buttons. Camera cuts and his shirt is done up and his tie is done. (00:34:45)
Box Cutter - S4-E1
Continuity mistake: When Gus is putting his orange jumpsuit on, he puts one shoulder on, camera cuts and he puts it on again. (00:29:00)
Open House - S4-E3
Continuity mistake: In the scene whee Walt and Skylar are talking to Saul, his shirt unbuttons.
Continuity mistake: When Walt realises that Krazy8 is awake in the basement, Krazy's foot is sideways showing the tread of his boot. When the camera shows Krazy from the front, his boot/foot is now flat on the floor as it should be. (00:26:40)
Continuity mistake: When Jesse is lying on the rotating disc at the beginning of the episode, in the initial side view Jesse's head doesn't reach the centre of the disc. However, when they switch to an aerial view from the top down, he is lying on the exact centre. Presumably, Jesse's feet couldn't reach the ground to rotate the disc when he put his head on the exact centre.
Blood Money - S5-E9
Continuity mistake: After Walt comes back to Jesse's house and returns his bags of money to him, Jesse is sitting on the couch with his hand over his mouth as he looks off to the side. After Walt says that "it's your money, you've earned it" he goes to sit down on the couch with Jesse, his hand still over his mouth as the camera pans around. When it cuts to a different angle as Walt is sitting down, suddenly Jesse's hand is down on his neck.
Box Cutter - S4-E1
Continuity mistake: When Marie returns to her home and we see Hank bidding online on crystals, when she walks in and says she's back the side view of him shows his mouth hanging partly open. When it cuts to a different angle, his mouth is shut.
Continuity mistake: Mike yells at Jessie to make himself useful and find a gun. The shadows in these two scenes are very long indicating it was shot late in the day. In the next shots and rest of the sequence, the sun is overhead.
Continuity mistake: At the end of season 1, we see the meth get weighed and Tuco tell No Doze to give Walter some more money. However in this episode the scene is different. We see Tuco give Walter the money which already includes the extra money. (00:02:15)
Continuity mistake: We see Jessie with the torch to his pipe. Camera cuts and the torch has disappeared. (00:37:30)
Continuity mistake: When Jesse looks out the window at the RV, the door is wide open. When he gets outside, the door isn't open as wide. (00:11:50)
Continuity mistake: When Walt is talking about his operation, in the hospital Cafeteria after Hank is shot. He says the line "Lying there waiting for them to anesthetize you." From one angle, he is shown looking forward, while from the next angle, he is turned around facing Marie. (00:20:50)
