Visible crew/equipment: After John-Boy says goodbye to his family then walks up the road it cuts to Belle in her office, and when she says that Mr. Fairfield is a man after her own heart, the shadow of the boom mic is moving on the wall at the upper right corner of the screen. (00:03:40)
Audio problem: Very audible slight 'echo' when Erin is talking with Mary Ellen in her bedroom about putting things off.
Other mistake: When Erin leaves The House to go with Ashley Jr., Elizabeth states to the kid that it's 3 a.m. When Ashley stops The Car to propose to Erin moments later, it is sunrise between the trees or early daylight, meaning this was a moment shot in different increments.
The Starlet - S8-E6
Visible crew/equipment: Shadows from booms and camera corners are quite visible in several shots around Erin's office and the plant exterior as the "film crew" is shooting.
Continuity mistake: When Verdi is sitting on Josh's bed, talking to him about being a man, the medium shot has her face tilted to the left. But in the immediately close-up, it's suddenly to the right as she finishes her comment.
Visible crew/equipment: Camera lights are visible in the reflection of Maude's glasses in several scenes.
The Seashore - S6-E5
Continuity mistake: Maryellen's pregnancy changes during the episode from her natural woman figure to a slight baby bump to a 9-month belly near the end.
The Inferno - S5-E20
Audio problem: When the Hindenburg explodes, audible screaming and panic of ladies' voices are heard in the foreground, but no crowd is present on the airfield except for the Naval aircraft workers.
The Inferno - S5-E20
Audio problem: While Johnboy and the press guy park, the Hindenburg is hovering over the aircraft field, while audible voices cheer alongside clapping and shouts. Yet, there is no visible crowd, but a small scattering of Naval comrades on the field. (00:17:23)
Continuity mistake: Elizabeth's hair length doesn't match while on The Ferris Wheel. The shot from the ground is very long hair 'draped' over the back of the seat. Yet, in the following close shot of her, it is from the chest up, so only the very bottom strands would be visible over the edge.
Continuity mistake: Or revealing mistake: Olivia's hair is suddenly long and braided in its "normal" length after her disastrous perm in the last episode 'The Rebellion'.
Revealing mistake: Her scalp 'shifts' slightly when Olivia fusses with her curly 'do, indicating it's an obvious wig.
The Secret - S4-E16
Continuity mistake: The view outside Johnboy's bedroom window is a tree within feet when no such tree exists in prior episodes. In fact, all the bedroom windows face the driveway.
Audio problem: A very audible echo is heard when Jon-boy says "I'm trying to work up there".
Revealing mistake: The wall in Jon-boy's room 'jiggles' a bit as Erin is confiding in Jon-boy about Maryellen, indicating it's either a set piece or an office partition instead of an exterior wall.
The Fighter - S4-E3
Revealing mistake: The Woman spectator at the boxing match is wearing an obvious 1970s fashionable floppy sun hat and dress, instead of an appropriate 1930s style.
Deliberate mistake: In the opening of seasons 2 onwards, there is a photo of Olivia outside the Church with the family. This is a scene from Season 1 Easter Story. However, it had to be from an outtake because the position of Erin, the absence of Jason, is different than what is shown in the episode. It's just something I noticed when I identified from where the shot was taken.
Factual error: When Olivia gets polio, she is at home. John is allowed to stay with her 24/7. It seems unlikely that the doctor, even if not taken to hospital, would allow John to stay in the room and risk contamination.
Audio problem: When Todd Cooper says "Good job" to Job-Bob while examining Jim-Bobs wooden plane int he boys' bedroom, it makes a very distinct echo that lingers for almost 30-sec, and then repeats very faintly in the next shot. (00:03:20)
Continuity mistake: Esther's wedding band is missing from her finger while she's sweeping and talking to Maryellen on the stairwell. But seconds later when she heads outside it's suddenly back on.
