Continuity mistake: When the woman is collecting the clothing at the Hi-Lo Mart, the position of the shoes she is carrying changes between shots. In the first shot the toes of the shoe are pointed at the ground, In the second they are aimed up over her shoulder. (00:03:00)
One Minute - S3-E7
Continuity mistake: Just after Hank crushes Leonel's legs by backing into him, Marco starts shooting into Hank's Jeep. You can see Hank crawling into the rear seat to escape through the side door. But as soon as the camera angle changes to inside the Jeep, Hank is back in the driver's seat and crawls out again. (00:43:30)
A No-Rough-Stuff Type Deal - S1-E7
Continuity mistake: While Walt and Jesse are talking with Tuco at the junk yard for first time, the sun changes between shots.
Continuity mistake: When Mike and Walt and Jesse are driving toward each other in the desert and they both spin out to avoid a wreck, Mike can be seen leaving his Cadillac, which is in the middle of the road/tire tracks, and the front wheels are in the tire tracks. In the middle of the scene, the Cadillac has moved to the right slightly, but is still in the road. At the end of the scene when the three drive off together, the Cadillac is seen off the road, having moved significantly to the right without a driver present. (00:15:15 - 00:16:45)
Crazy Handful of Nothin' - S1-E6
Continuity mistake: When we see the red liquid being injected into Walt, there is a lot of liquid in the syringe. Camera cuts and there is suddenly much less. (00:18:10)
...and the Bag's in the River - S1-E3
Continuity mistake: When we see the basement while Krazy-8 is alive, we can see that there is no light coming in from outside or any windows. When Jesse returns and goes to the basement all of a sudden there is loads of daylight streaming into the basement. (00:42:10)
Continuity mistake: In Season 4 we see Mike gets shot in the ear and and has a flap of flesh hanging off. In this episode, there are no marks or deformities on his ear.
Problem Dog - S4-E7
Continuity mistake: When Jesse is emptying the cigarette, his fingers are right at the end of the cigarette. Camera cuts and now they are up the other end. (00:19:20)
Box Cutter - S4-E1
Continuity mistake: During the diner scene when Jesse is eating, Walt asks him how he's doing. Jesse's head changes positions several times between shots. From looking out of the window, to back down at his plate, to back out of the window, to straight ahead again, all between shots.
4 Days Out - S2-E9
Revealing mistake: There are no water cooling tubes attached to the reflux condensers. Reflux condensers do not condense without cooling. (00:15:40)
One Minute - S3-E7
Other mistake: At the end, we see the gunfight between Tuco's cousins and Hank. Several shots are fired, cars smash into each other, a woman runs off screaming. So not a "quiet" attack. However, as the camera zooms out to show the carnage, 2 people who are not involved in the attack, are just stood talking in the car park. A bit odd since there has been a very clear shoot out. (00:44:50)
Suggested correction: Nobody is actually standing in the car park. People are standing around on the sidewalks talking to each other about what was going on, keeping their distance. Personally I would keep a bigger distance, but whatever distance they feel safe with.
Continuity mistake: At the end of the episode when Walt and Jesse are leaving the junkyard, the camera pans to Tuco and Ganzo watching them drive away. However, this is at the same time Ganzo is moving No Doze's body and is subsequently crushed by a car.
