Continuity mistake: When Dennis Leary and Michal J. Fox are at the bar, the shot Michael J. Fox has changes from being empty to partially full between shots, multiple times.
Visible crew/equipment: In the episode "Head over Heels," twice you can see the cameras mounted on the walls that are used to film this series. The first one is during the cross-examination of Miss Morris and the second time is during the defence summing-up.
Continuity mistake: In the scene where Maria talks about wanting to throw the vase to the floor, the vase changes between shots. When she eventually throws it to the floor it's the original vase. This was most likely done due to a retake that had to be shot after the original vase was thrown to the floor and destroyed.
Continuity mistake: In the opening scene where Tommy and Jude are composing a song, Jude's head is turned to the side in a wide shot. In the following close-up shot, her head is staring straight up and not turned to the side.
Plot hole: In order for the show to be starting on "Day 1,412" as counted back from Cooper's eventual high school graduation, it would have to be a mere 49 days after his graduation from the eighth grade. (4*365 = 1460 + 1 for leap year) So it should be the middle of summer, but instead the school year seems to be in full swing. For example, it's already the end of Natalie's soccer season.
Continuity mistake: Bob Fossil records Howard saying "Gorilla" on his talk box, which Howard does with a downward inflection at the end of the word. However, every time Fossil plays back Howard's "Gorilla", it has an upwards inflection at the end of the word.
Deliberate mistake: Before each season begins filming, each potential apprentice is filmed leaving Trump Towers and entering the taxi as if they were just fired. Once the person is actually fired on the show, this becomes an obvious mistake as hairstyles, etc. change from the boardroom scene to the cast member's exit.
Factual error: At one point the barristers are seen going into the old arch entrance of the Old Bailey. However, you cannot actually go in that way, it's blocked off, you have to go in the more modern entrance and through a series of security checks.
Continuity mistake: When Brian and Gerry are chasing Kelly, Kelly's jacket is only zipped up at the bottom at the start of the chase, but when the camera angle changes it is zipped all the way up for the rest of the chase.
Factual error: In episode 2-11: "Safe House," Bradin's PSAT score report is shown. He has a 726 verbal and a 746 math, for a total of 1472. However, the PSAT has three sections - verbal, math, and writing skills - and each is scored on a scale of 80 points, not 800. So PSATs run on a scale of 240, not the familiar 1600 that the SAT used until earlier in 2005.
Continuity mistake: It is established that having matter from one universe in another causes it to deteriorate, but the parallel universe doorway closed, even though the photo of Ben and Buster is left in the alternate house. There was brief panic that the chaos wasn't over, when they thought Buster had brought a new collar from the alternate reality, but the photo was forgotten about and the worm-hole thing closed, despite the photo being on the wrong side.
Visible crew/equipment: Towards the beginning, when the Taliban steps on the landmine, you see the DEA agent getting hit with dirt and blood. In the center of the shot, you can see a few drops of blood stick to the camera lens. Incredibly easy to notice, so I'm not sure how this one slipped through.
Coming Home - S1-E3
Factual error: At the convalescent home, Dr. Conner asks if a lector has been to the home to give communion. Later, he describes a lector as a person who gives communion at church or to the homebound. A Eucharistic Minister or Extraordinary Minister of Holy Communion gives communion in the Catholic Church.
Continuity mistake: In the scene where Mr. H. Makes Bloo wash his hands, Mr. H takes off his gloves and washes his hands then dries them. Notice that as soon as he takes his hands out from underneath the towel his gloves are back on.
Episode #3 - S1-E3
Audio problem: When Muhammad is meeting with the group of Al-Quaeda leaders in the desert, the movements of his mouth do not match what he is saying in the foreign language.
Continuity mistake: In two episodes aired consecutively on CBBC on April 7th 2004, The "DON'T WALK/WALK" sign moves from one side of the crossing to the other and changes colour. At the end of the episode where Bernie has a lucky watch, the sign is to the right of the main door to the apartment building and has orange text. At the start of the episode where Bernie finds a cat, the sign is to the left, and red.
Continuity mistake: When Shirley walks through the door you can see over Alan's shoulder that he's reading the comics in the daily paper. As they talk the paper changes to the business section.
Continuity mistake: At the end of the battle between Jaden Yuki and Gravekeeper's Chief, just as the explosion settles, in one shot you see the Gravekeeper's Spear card to the left of Gravekeeper's Chief on the duel disk. However in the next shot Gravekeeper's Spear is replaced with Magician of Black Chaos, which Chief neither has in his deck or ever played in the match. (00:13:35)
Continuity mistake: In the episode where they overhaul a 1976 blue van, there is a shot of the white donor van being carted away. Yet later on in the same episode, the white donor van is back in the workshop.
