Visible crew/equipment: During the shot from the interior of the car of Hank following Jesse, a camera man in a green T-shirt can be seen crouching down on the road to the right of the screen. (00:30:40)
Other mistake: Throughout the show, during the into credits, people's names have 1 or 2 letters replaced by green characters to symbolise elements from the periodic table. However, Michael Slovis has the 'Ch' highlighted. There is no 'Ch' on the periodic table. (00:03:20)
Visible crew/equipment: Just as Walt is saying the line about checking to see if the other one is dead in the RV, the edge of the set comes into view very briefly on the right hand side. (00:15:10)
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.
To'hajiilee - S5-E13
Audio problem: After Hank and Gomez separate Jessie and Walt after he's arrested, Hank tells Gomez that "I'll call the Tribal Police on my way out, let them know we're here." During the middle of this line, the shot cuts to Walt and you can distinctly hear the sound of a microphone picking up the actor breathing on it as he recorded this line in ADR.
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)
Green Light - S3-E4
Visible crew/equipment: Skyler is making copies and the scene starts with a shot looking down into the copier (the Green Light). When the shot lightens a bit as the copier continues, you can see the camera lens. This makes sense because the camera is sitting directly on the copier looking down.
Crawl Space - S4-E11
Factual error: When the doctor is reciting Jesse's medical information, he states that he is 1.87 meters, which would make Jesse 6ft 3 in. Aaron Paul is only 5ft 8 in. (00:07:42)
Suggested correction: First, the doctors says 180 centimeters, not 1.87 meters. 180 cm is 5'10." But it's not a mistake if characters are a couple inches taller or shorter than the actors that play them. Just like often characters can be older or young than actors that play them.
Continuity mistake: Walt is making pancakes and there's 1 pancake left in the pan. Skyler walks in and now there's 2. (00:04:35)
4 Days Out - S2-E9
Visible crew/equipment: Walt and Jesse get stranded out in the desert. We see Walt cough up some blood and Jesse stand behind him. In this shot you can see the reflection of someone move in Walt's glasses, despite them being alone and still. (00:32:30)
Continuity mistake: The amount of glass on the floor changes after Walt breaks the light. (00:07:10)
Visible crew/equipment: When Walter talks with Jesse outside the Mesa Credit Union, just after giving him the money to buy the RV, a boom mic pole can be seen reflected on Jesse's car door. (00:36:12)
