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.
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.Jon Sandys
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.Quantom X
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.Quantom X
