Other mistake: In the starting titles, the newspaper clippings state that Doogie sails through high-school in 9 weeks, the article says he is 12 years old. The next clipping says he graduates from Princeton at age 10.
Dedication - S1-E7
Other mistake: At about the 8 minute mark SnakeDoctor is talking on the radio to Bushmaster who is on the ground. There is a few seconds long shot where Bushmaster's earpiece is dangling wires and not connected to his Comms Gear on his vest. That earpiece can't be wireless.
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)
Other mistake: The closing credits on the DVD are for another episode, "The Kidnapped Prime Minister." (00:47:15)
Mona Lisa's Revenge (1) - S3-E10
Other mistake: Mr. Smith scans the Mona Lisa and determines that it is genuine from DaVinci's brush strokes. He should have also noticed the words "This is a fake" written in felt tip under the paint, from when The Doctor replaced the Mona Lisa with one of DaVinci's "forgeries" in "City of Death."
Through the Looking Glass - S5-E19
Other mistake: Danny supposedly handcuffs an at-risk teenager. When the police officer takes her away to a cell, the girl isn't handcuffed. The handcuffs are just in her hands behind her back. (00:52:00)
Other mistake: Before the security guard is killed, he turns around and faces the direction of the camera. He is killed, and the camera backs up to reveal 6 men standing there. The security guard would have seen the men and he had time to react to them, but did nothing. (00:32:50)
Other mistake: When everyone is mounting Lefty after escaping the temple, part of the lava flow directly on the right of the opening goes nowhere and just ends halfway down the screen.
Log 51: A Jumper, Code 2 - S1-E19
Other mistake: Halfway through the show, the officers walk across the street to talk to some young toughs. The school sign painted on the street is spelled "Schol".
Other mistake: When Lorne Malvo shoots out of the window the only thing sticking through the newspaper is the gun's barrel. When the shot changes to the scope view, you can see the outside. But you shouldn't be able to look outside.
Cold Murdering Bastards - S3-E2
Other mistake: When we see the Royal Gazette, with the misinformation about Washington's death, the 2nd column is repeated in the 4th column.
Home for the Holidays - S11-E1
Other mistake: Only one set of prints were said to be on the garrote but in the last episode of season 10 Graham handles the garrote before handing it over to the murderer without wearing gloves. So there should have been 2 sets of prints.
The Case of the Sausalito Sunrise - S9-E19
Other mistake: The owner of a Los Angeles trucking company tells a driver who is going to San Francisco, "Take the San Diego Freeway toward Bakersfield." That freeway runs from San Diego to San Fernando. It does not go toward Bakersfield.
Other mistake: When we first see the Saito Gemu HQ, the shot is mirrored. It is apparent by the reversed company logo sign. (00:14:25)
Other mistake: When Cobb starts to chase the red Dodge, there's a shot of him passing between two vehicles (and very distinct buildings in the background). When Murphy picks up the chase, this same shot is reused, showing her passing between the same two vehicles.
Other mistake: When Voight finishes talking with Rev, Voight walks away. When he does, he goes in the opposite direction from where his car is parked and on the wrong side of car for a driver. (00:27:05)
The World Needs Heroes. Over. - S2-E9
Other mistake: The Doctor, coming up from the basement of his house, is locking both deadbolt locks using a key held in his right hand. He logically would use the same hand to put the key in his upper left pocket. Richard who is watching through binoculars uses a walkie talkie to inform both Ezra and Jules that the Doctor has put the keys in his upper left pocket. However, the next scene shows the Doctor with keys now in his left hand placing the keys in his upper right pocket. This doesn't match what Richard says he observed. (00:24:42)
Chapter Sixty-Eight: Quiz Show - S4-E11
Other mistake: Archie's uncle Frank tells Archie during an argument with him that he is 40 years old, with seven years in combat while in the military. But in a previous episode when explaining why he let Fred take the blame for his DUI, he claimed that he was a Desert Storm veteran in between tours at the time. Either the show got the wars wrong and meant to say he was an Operation Enduring Freedom or Iraqi Freedom veteran (no actual veteran uses "Desert Storm" when referring to combat in the Middle East after 9/11) or they're saying that he was only 10-11 years old when he went to Desert Storm. (00:29:30)
Other mistake: When Michael walks into his office and sees Shawn, Michael is wearing a wedding ring. Looks like he forgot to take it off prior to shooting the scene. (01:00:00)
Liar's Poker - S3-E3
Other mistake: Her name in the show is Elise Taylor, but on a badge in her car it's Elise Smith.
