Visible crew/equipment: When the chauffeur opens the limo door, the camera and film crew are reflected in the window. (00:03:10)
Factual error: While Edgar Allan Poe is penning his famous poem, a close-up of the paper shows us that he's misspelled his own middle name as "Allen." (00:00:50)
Factual error: Ellis trots up the stairs with his wife's dinner, shaking and bouncing the tray all the way. But when he arrives, the liquid in the tray's very full glass of milk hasn't spilled a single drop. (00:14:30)
Since Aunt Ada Came to Stay - S2-E9
Continuity mistake: When she leaves the campus, Joanna gets wet running through the rain to her car. Just minutes later, she arrives home completely dry and with her hair neatly coiffed again. (00:27:10)
The Messiah on Mott Street - S2-E38
Plot hole: No one in Goldman's house finds it at all strange that a mailman arrives at the door with a letter after midnight on Christmas Eve. Nor, a short time later, does the doctor or anyone else passing by at this very odd hour wonder why the same mailman is collecting mail from a street box at dawn on Christmas Day.
The Tune in Dan's Cafe - S2-E45
Continuity mistake: When Roy is talking to Dan through the window while a hamburger is frying, the camera angle switches and there are suddenly 2 uncooked patties on the griddle.
I'll Never Leave You - Ever - S2-E56
Continuity mistake: Several times during this episode, reversed shots cause Moira's wedding ring to switch from her left to her right hand and back again.
Factual error: Gingold's Camera Obscura shows us a cross-fade. That's a special effect the Victorian device wasn't capable of performing. (00:06:45)
Factual error: Muñoz's name is misspelled on his headstone as "Dr. Juan Munos," omitting the tilde and changing the z to an s. (00:02:15)
Visible crew/equipment: In the 1920s, Agatha takes a taxi to Muñoz's house. In the background, through the taxi's rear window, you can see a large white 1970s Universal Studios panel truck being loaded next to another building on the back lot. (00:02:45)
Dr. Stringfellow's Rejuvenator - S2-E28
Continuity mistake: In the saloon, Stringfellow pours himself a drink and picks up his glass. When the camera angle reverses, his glass is back on the table and his hand is on the bottle instead. In the next shot, he's holding the glass again. (00:11:30)
Continuity mistake: During Juan and Agatha's dinner together, the camera circles them, passing behind Juan (where an "invisible" cut occurs) and continuing to move left around the table. Between the two segments, the position of Agatha's hands changes noticeably. (00:11:50)
Dr. Stringfellow's Rejuvenator - S2-E28
Audio problem: When Stringfellow beats his drum to attract a crowd to his medicine show, the sound doesn't match the strikes he's making with his drumstick. (00:01:00)
Visible crew/equipment: When the landlady opens the glass-paned door, it reflects a large, round studio light. (00:04:10)
Continuity mistake: While she talks to Mrs. Gibbons on the stairs, Agatha's paper sack changes its position and appearance several times between shots. (00:16:15)
Last Rites for a Dead Druid - S2-E52
Visible crew/equipment: After Jenny and Mildred find the statue Jenny calls for Mr. Bernstein, and when Mr. Bernstein walks into the room the white tape T-mark can be seen on the rug where he stands.
Continuity mistake: It's the 1800s, and Dicter rides up to a building that has every window, upstairs and down, blazing with what is obviously electric light. When he walks into the ground floor saloon, however, there are no bright lights. It's dark and dim inside. (00:03:00)
Continuity mistake: As Kyra is leaving the village, Logoda's fang necklace, in close-up, has two of its teeth flipped over and out of alignment with the rest. In full shot, though, all the teeth are back in perfect order. (00:09:10)
Visible crew/equipment: While the janitor works on Justice's thermostat, a large piece of blocking tape can be seen on the carpet in front of the door in the background. (00:09:15)
