Audio problem: When Michael is forced to do "errands" for Brennen, they stop by Jonathan Carver's house to get numbers from him for a voice key. The code played back at the facility is 71348. He says "3" in a medium pitch (tone) at the house, but it is high pitched when played back at the facility; he says "8" in a medium pitch, and it's also high pitched later. And finally he says "9" in a low pitch and it's played back medium pitch. Also very obvious is the fact that Jonathan never says "1" or "7."
Visible crew/equipment: When Michael breaks into the car, after he drives off you can see a camera standing in the back seat in the car, and it's pretty clear it's a stunt man driving. (Helps to pause at 18:07.) (00:18:05)
Continuity mistake: During the scene when Michael is attempting to deceive Brennen into letting him and Nate go (from the time Brennen receives the picture message to when Brennen leaves), Brennen's necktie (right below the knot) changes from having a dimple to being flat, 6 or 7 times during the scene.
Revealing mistake: When Victor is opening the padlock, sparks fly around in close ups. In the wide angle shots there are no sparks at all.
Old Friends - S1-E3
Continuity mistake: Near the end of the episode when Mike is threatening the Assassin, by withholding his allergy shot. The needle flips instantly in his hand between shots. Noticeable because of the black tip on one side. (00:39:05)
Good Soldier - S2-E9
Revealing mistake: As Michael is on the motorcycle headed toward his loft, just before he goes under the semi-trailer, you can see the long hair of the stuntman on the bike.
Revealing mistake: When Sam pops open the cabinet with the wire he will later cut, you can see that the wire was cut and glued together again. When Sam cuts the wire some time later, it's in perfect condition. The taping was probably done in reverse order.
Hard Bargain - S1-E9
Visible crew/equipment: When Michael drives away at the end of the first scene, you can see a boom mic reflected on the car's surface.
Continuity mistake: When Michael is talking to Walter, the art dealer, the latter has his hands folded together. In the next shot he has one hand on his lap and the other on the table. (00:35:20)
Continuity mistake: At the end of the episode, before the SUV rolls, it is a new Escalade. However, during and after the roll, it changes to a first generation Escalade.
Continuity mistake: When Hector, Caleb, and Michael walk to the back of Caleb's house looking for the GTO, they discover it behind the greenhouse. Caleb tells Hector he'd never steal from him. Hector gets in Caleb's face and says, "You mean, you never will." Here, Caleb is shown from the front. When Hector says "again," Caleb is shown from behind, and he has sweat running down his cheek. When Caleb is shown from the front again, Hector says, "Take him inside," and there's no sweat on his face. (00:35:40)
Hard Bargain - S1-E9
Other mistake: When one of the kidnappers knocks on Michael's door, it shows him undoing a sliding barrel bolt before opening it, but the bolt does not have anything it slides into on the door frame rendering it pointless, especially as the door opens inwards. (00:30:20)
Continuity mistake: Michael makes the target/client use a faulty pen that spill ink all over her hand. When Michael is in the bathroom and holds over the targets mouth, his shirt gets dirty of the ink from the target/clients hand. After this, it switches between the shots and Michael having a dirty and clean shirt several times. (00:10:53 - 00:11:46)
Factual error: When Michael attempts to start the Charger, the starter just clicks, indicative of a dead battery or faulty starter. He checks his father's logbook and reads "spark plugs." Unless the cylinders are filled with an non-compressible liquid, there is no way that spark plugs are going to prevent the engine from cranking.
Continuity mistake: Xavier's henchmen show up at Oswald's associate's house with 2 Escalade SUVs. Then, one more Escalade, same year as the 2 others, shows up behind the house. As soon as Michael says "We've got another one coming up. Third," the next shot of the Escalade shows a much older model.
Continuity mistake: Michael is having a meeting with the guy who is asking how Michael found out about him (where Sam is standing guard with the sniper rifle.) Michael has a gun pulled on him and is trying to escape. As Michael is trying to leave in the Charger, he pulls backwards and makes a 90 degree turn so that the passenger side of the Charger is facing the guy with the gun. The windshield could not have been shot from this angle. The next camera shot Michael is driving backwards again with the windshield facing the guy so he can shoot a hole in the center of Michael's windshield.
Do No Harm - S2-E10
Revealing mistake: The drawing little Jack made was reproduced on a printer; it has a perfect 1cm white border around the drawing.
Continuity mistake: When Ricky leaves Michael's apartment he has the envelope with money in his left hand. When the shot changes, we instantly see him walking away empty handed, with the envelope lying on the table.
Continuity mistake: Just after Michael throws his mothers cigarette out of the car, there is a shot from the inside through the front window. There is a large crack in the glass, bottom left of the rear view mirror. When the car is shot from the front, there's no crack. (00:24:30)
Chosen answer: It might not actually have one, in which case, he'd have to go down into the club and use theirs. As for showering, going to his mother's house or a gym membership would take care of that.
