Continuity mistake: When Jimmy is talking outside the courthouse, pretending to be his secretary, he puts his case on his car roof. In the first shot the white aerial is visible in front of his case. Shortly afterwards it's hidden, either behind or on top of his case, without him touching anything.
Continuity mistake: After James hits the roller blade guy, when the two brothers run away the sun changes between shots.
Continuity mistake: While James is arguing with Tuco in the desert about the twins the sun changes in several shots.
Continuity mistake: In the desert when Tuco and Nacho are interrogating Saul, the sun and sky change half a dozen times. When he is being cut free, the sun is to his left. The next shot it's overhead. The continuity gradually improves as the scene goes on.
Factual error: Tuco Salamanca's gun is a Taurus Raging Judge. Season 1 - as well as Season 2 - where Tuco's gun is prominently featured, are set in 2002. The Taurus Judge series wasn't produced until 2006.
Continuity mistake: Out in the desert when Jimmy is tied up, they decide to let him loose. Tuco's thug goes behind him, and James has his hands duct taped behind is back. The thug bends down to cut the tap, and then the camera cuts to a rear view. As the thug pulls the tape away, Jimmy's hands are suddenly instantly in front of him at his sides and he's leaning forward.
Other mistake: When Jimmy goes looking for the Kettlemans, he climbs up the Sandia Mountains but finds them in a flat forested area. To get to a level forested area in the Sandias, Jimmy would have had to climb all the way to the top, which would be suicidal, because the area of the Sandias he goes into is extremely rugged and steep, plus he goes in there with nothing but a suit. Even the Kettlemans would be insane going that same route with two kids, a tent, and camping supplies in tow.
Factual error: While Jimmy is climbing up the billboard to save the worker, some buildings can be seen in the background such as the TriCore Labs, Embassy Suites Hotel, and the Bernalillo County Metro Court House. This episode is set in 2002 but the Embassy Suites and TriCore Lab buildings weren't built until 2004 and 2005 while Metro Court was still under construction at this time. Even the billboard tower in this scene didn't exist until years after it was set.
Factual error: The intro scene for this episode shows Mike getting off the Rail Runner Express. This train didn't come into service until 2005. This scene is set in 2002.
Continuity mistake: When James McGill returns from the toilet, Craig Kettleman is rubbing his hands. In the next shot he is holding a cup with the right hand and his left hand is hidden under his right arm. (00:25:05)
Visible crew/equipment: At the end of the episode Saul is sitting in his office and you can see the shadow from a crew member in the windows. The member even moves. (00:50:41)
Other mistake: In episode 3 Jimmy says to Kim that the Kettlemans bought a boat using some of the money they embezzled. Nevertheless, when Mike breaks into the Kettleman's house and gets the money back which later is delivered to the district attorney in this episode, it's the whole amount without any money missing.
Visible crew/equipment: At the end of the episode you as Jimmy is sat on the floor, you can see the head of a camera man or sound technician duck down to the left of Jimmy.
Factual error: When Mike is waiting in the parking garage with Sobchak for Pryce to arrive, the AT&T logo is prominently displayed on an office building in the background. This logo is the new style introduced in late 2005 and didn't exist in 2002 when the show is set. (00:11:25)
Continuity mistake: In the parking garage, the guy to Mike's right starts talking about the blood of some ethnics running hotter. When he says it's physiology, Mike is looking straight ahead. The camera then cuts to a wide angle showing all 3 guys and now Mike is looking off to his left.
Continuity mistake: While talking to Marco, when the bartender asks them if they want something else, James McGill is holding a beer bottle in his right hand. In the next shot the bottle is in the center of the table. (00:20:00)
Factual error: In one of the shots shown of Chicago, the Trump Tower can be seen on the right. Although the episode is set in 2002, this building did not exist until the late 2000s. (00:28:33)
Continuity mistake: During Jimmy's rant during Bingo, B5 is flashing on the main board (the last number he read out loud). It switches to B2 flashing when he says he got on top of the BMW. B5 is then seen flashing again, on the board in the back, when he's finishing his rant.
Continuity mistake: When Jimmy is in the pool and calls to get the number for Davis and Main, his feet are uncrossed. But in the next shot of him, his feet are crossed.
Factual error: In the scene of Jimmy driving with his new Mercedes, we can see a Subaru forester that is definitely a model after 2010. Season 2 is set in 2002 so this couldn't be possible.
Answer: It might be the Panavision cap he wore when directing his terrible commercials.
