Continuity mistake: An employee is asked to leave the computer lab, he actually exits it twice. (00:11:15)
Chapter Five - S1-E5
Factual error: Pete uses the term "throwing shade" when talking to Perry Mason in the middle of the episode. As this show is set in 1932, the phrase "throwing shade" did not yet exist (the phrase was first introduced in the 1990s). (00:35:00)
Suggested correction: The phrase was not first introduced in the 1990's. While it did become popular in the 1980's, the idea of "throwing shade" as an idiom would have been around before then. A variation of the idiom is found in writings from the 1800's, for example "Mansfield Park" by Jane Austen.
Factual error: At the end of the episode, as the veterinarians are leaving the pub, the camera pans up to the sky and you can see the full moon right next to the north star and the big dipper. In the northern hemisphere the moon is always to the south.
Continuity mistake: Throughout the series, the Barbers pull their cars straight up their driveway. But the cars are nearly always shown coming back down the driveway driving forward.
Continuity mistake: When Jonah confronts Meyer after the death of the surgeon, Meyer's holding a drink in his left hand as he turns to face Jonah. The shot changes angle and the drink is suddenly in his right. (00:48:40)
