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)
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)
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)
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: 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.
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)
Hard Bargain - S1-E9
Continuity mistake: When the kidnapper holds Michael at gunpoint on the balcony, his hand holding the gun is shaking. In the next shot, from behind, his hand is perfectly still. The shot then switches back, and his hand is shaking again.
Broken Rules - S1-E7
Continuity mistake: Michael has to prove himself for his new "boss" Concha Ramirez. He walks across the street to Fiona and starts a mock robbery to get her purse. When he approaches the car, the window is down. Three seconds later he is at the car and the window is up so Michael can break it. Watch as the window frame goes from clean (as if the window were down) to broken pieces of glass on the frame between shots. (00:24:10)
Wanted Man - S1-E8
Continuity mistake: When Michael is eating his slush, the way he holds his cup changes between shots.
Continuity mistake: When the heroin importer is questioning Sam, he has his hand around his face, with his fingers touching his ear. When the shot moves to the front, his hand is more on his throat and nowhere near his ear. When we cut to the back, his hand moves again.
Continuity mistake: When Sam bugs Ari's Ferrari, he places the bug under the dash cowl above the steering wheel. Near the end, after the Zamir family's warehouse is found empty, the father is shown searching his son's Ferrari and pulls out the bug from behind an air vent on the passenger side, not where the bug was originally placed.
False Flag - S1-E10
Continuity mistake: When Michael is talking to Evelyn she picks up her glass and brings it to her mouth. When switching to a different angle her glass is back on the table, and she has her hands on her lap.
False Flag - S1-E10
Continuity mistake: While the team is driving to drop Doug off at the Attorney General's office, there are multiple times that the camera shows Michael riding with Fiona in the trailing car, however when they arrive she is alone and Michael is on the roof behind Evelyn. (00:36:20 - 00:37:25)
Continuity mistake: When Michael is on the phone with the heroin dealer at the docks, he has his phone at his left ear. When the camera moves to a shot from the back, there's no phone near his face (or in the frame for that matter) and his mouth doesn't move while talking. When the shot cuts back, the phone instantly is back at his ear.
Old Friends - S1-E3
Other mistake: This Jan Haseck assassin, who has either multiple allergies or else one allergy to a very common substance (peanuts), could never do any espionage work, as it would make him too vulnerable.
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.
