Rockets, Communists, and the Dewey Decimal System - S1-E2
Other mistake: As Young Sheldon is a prequel series to Big Bang Theory, this episode is at odds with episode 2-13 of Big Bang Theory, "The Friendship Algorithm," in which Sheldon is unfamiliar with books like "How to Make Friends and Influence People," which he reads in this episode of Young Sheldon, produced nine years later but taking place twenty years earlier.
Old Wounds - S1-E1
Continuity mistake: When the Krill shuttles land, they park on either side of the entrance to Epsilon station, but when the Orville crew are escaping, the Krill shuttles are gone momentarily (during the firefight), only to return to their proper places a moment later as the Orville shuttle takes off. (00:33:40)
Factual error: In the opening sequence when Maddie is supposedly driving from Michigan through Ohio and back to Pennsylvania, you can very briefly spot the reflection of a "TD Canada Trust" in the car window. This is because the show is actually shot in Vancouver. In the United States the company is simply known as "TD Bank", which doesn't operate any branches in either Michigan or Ohio. (00:01:55)
Wuffenloaf - S3-E1
Plot hole: When Abby and Eric return the night vision goggles, Abby asks if they should put them back exactly where they were and Eric says he didn't remember where they went but luckily he "took a picture" of how it looked before. How could this be possible if Abby purposely excluded him when she collected those goggles from Lisa?
Continuity mistake: When Midge is doing her makeup routine, she doesn't have eye liner, then she does, then she doesn't.
Out of Time - S1-E3
Continuity mistake: When John meets Brooke and is examining her wrist, he ends up holding her hand palm up, but in the next shot her palm is facing down.
Continuity mistake: When Deborah is talking to Mrs. Chadwick, Mrs. Chadwick's hair keeps changing position and is either covering or not covering her name tag. And when the camera is on Deborah, we still see Mrs. Chadwick's head and she doesn't move it at all.
Continuity mistake: Outside Rusty's bar Lucy says she's staying in room 114 of the Marlowe Inn. When Brockmire goes to see her, she's in room 411.
Continuity mistake: When Emily looks over at Wendy, Teddy, and Ron, they're huddled together and start walking away, still huddled. In the next shot, they're separated and Wendy is already a step ahead of Teddy and Ron.
Other mistake: When the interviewer asks the girl what she was doing March 15th, 2016, she says she was shopping. However when the receipts are shown they say 05/15/2016. (00:10:50)
Continuity mistake: When Evan is out with Doug it is day time. Evan proceeds to get out his cell phone to text Casey. Then we see Casey and it's nighttime. (00:11:50)
The Buffer - S1-E3
Continuity mistake: When Mickey touches Trish's boob, her hand is over the grey shirt, in the next shot, her hand in inside the grey shirt, and over the grey shirt again in the next shot.
Continuity mistake: When Josh is asking his dad if the cops were hot, from the side he's leaning forwards with both elbows on his knees, then from the front he's more upright with one hand on his knee, arm bent out to the side. (00:09:45)
Continuity mistake: The way "Jack Griffin" is written on the board changes in various shots.
Revealing mistake: When Andi walks into the library (this is not Andi's dream) it cuts to the librarian sitting at her desk and we can see the shot is flipped - note the bookcase and the librarian's buttons. (00:10:40)
Other mistake: There is a countdown on the movie screen. It is then reflected in Dusty's glasses. But the numbers are not reversed in the glasses. (00:41:00)
Audio problem: Right after Carol finishes studying by singing a rap to Katie, Katie congratulates her and Carol hurries out. They exchange several lines of dialogue, but it all appears to be dubbed. During most of the dialogue, each character's mouth is not shown when they speak. However, the cadence of Katie's moving jaw can still be seen from behind, and appears to last longer than the audible speech. Additionally, Katie and Carol can each be heard to speak when it can be glimpsed that their mouths are not moving.
Boundaries - S4-E3
Continuity mistake: Alex and his mom are talking with Grandma about masturbation. Alex is in his school uniform shirt but for one shot he has a hoodie on, then in the next shot it's gone.
Factual error: In the last 2 episodes of series 2, when anyone uses a phone box it has the the BT Piper logo on the outside, which wasn't introduced until 1991 - six years after the series is set.
