Visible crew/equipment: While the family starts packing up their car with John's suitcases and boxes, right after John says, "I just don't want any kind of a big scene," a cluster of boom mics dip into view and stays there at the top of the screen, over Mary Ellen and Jason. Then in the closeup, as John agrees that they will all go see Olivia, a crew member wearing a blue shirt (with a front pocket) is visible in the vehicle's window reflection. (00:44:40)
Visible crew/equipment: When Jim-Bob delivers Betsy's mail she's washing her hair outside, and as she flips her wet hair back we can see the microphone under her halter top, while her arms are up. Then when she walks toward the cabin with Jim-Bob, the bulge of the mic transmitter is visible at the back of her shorts. (00:06:20)
The Scholar - S1-E22
Visible crew/equipment: When John drives off with Olivia and Esther while everyone shouts their goodbyes, just as we hear, "Have fun!" a director's chair is visible at the right side of the screen. (00:11:50)
The Bicycle - S1-E23
Factual error: While Ann is on the Walton's swing telling Curtis that he deceived and lied to her, when Curtis gets back into his car, a modern vehicle is visible at the right side of the screen, which is inappropriate for the time period. (00:46:10)
The Reunion - S1-E14
Visible crew/equipment: After Miss Emily tells her sister to serve some more Recipe to Homer and Zeb, when it cuts to the Walton house the set's c-stand lighting equipment is visible at the left side of the screen. (00:15:45)
Character mistake: When John-Boy reads the nursery rhyme "Simple Simon" to his nephew, John-Boy points to the colorful illustrations in this book and tells John Curtis, "See, that's Simple Simon, he's a bear." This is incorrect. In the illustrations, Simple Simon is a donkey, and it's the pieman who is a bear (he's wearing a chef's hat and apron). (00:40:50)
Visible crew/equipment: After John finishes checking on John-Boy's car, when it cuts to the kids in the bathroom, note the vanity mirror's reflection. In between Mary Ellen's and Jason's reflections, we can see an older man wearing black glasses, yellow shirt, and blazer, who is standing outside the bathroom's doorway. We continue to see the reflection of this crew member in the mirror when Jim-Bob and Ben go at each other. (00:04:25)
The Townie - S1-E24
Factual error: After John-Boy and Sarah's date at the double-feature, during the ride back home when John-Boy tells Sarah that there's nothing to makeup and he's not mad, through the windshield 1970s vehicles are parked directly ahead of John's pickup truck. (00:08:25)
Visible crew/equipment: When John-Boy falls off the ladder and breaks his wrist Zeb drives him to the doctor in the truck. During their drive we can see through the window behind them, and there's a crew member wearing a red shirt riding along in the back, as they drive past a parked 1970s station wagon. The camera and its operator are casting a shadow on Zeb as well. (00:18:25)
Visible crew/equipment: After Colonel Brunson's funeral it cuts to Rose in the living room, and when Elizabeth and Drew walk into the Walton house, the black T-mark is visible on the rug where Elizabeth stands. (00:07:00)
Visible crew/equipment: After Miss Hunter tells the class that the spell down between the finalists will continue the next day, when it cuts to the long shot of the kids coming home, we can see the crew's production truck at the top, right side of the screen. (00:17:35)
The Bicycle - S1-E23
Visible crew/equipment: When Curtis stops his car because Ann has been following him on Olivia's bicycle, while the couple are hugging we can see the reflection of two crew members on the vehicle's windshield. (00:48:10)
Visible crew/equipment: After Jason tells John that he left word with Ike for the Sheriff, Elizabeth runs into the barn worried about Pete. Then Gino walks over to his T-mark (plastic type) on the dirt ground and a second T-mark (partially covered in dirt) is beside it. Soon, John-Boy walks over to that second T-mark as he glances down to presumably be certain he hits his mark. (00:32:55)
Visible crew/equipment: When Judge Thornbury fails to convince John-Boy to kill the story on his car accident, Thornbury heads over to talk to John at the mill, and just as Zeb says, "Hiya, Judge," the boom mic pops up into view at the bottom of the screen. (00:17:40)
Visible crew/equipment: When Erin and Elizabeth help Daisy unpack in their bedroom, just as John-Boy walks into the room, the lighting equipment is visible at the left side of the screen. (00:20:55)
Visible crew/equipment: While everyone is on the porch talking about gifts for Elizabeth, after the little vase falls and breaks it cuts to a shot of the porch, and the set's c-stand is visible at the right side of the screen. (00:06:50)
Visible crew/equipment: While Mary Ellen is sitting on the couch reading Gone with the Wind during her break, when David walks in and sits down beside her, the shadow of the boom mic is moving around on the wall, at the right side of the screen. (00:16:05)
Continuity mistake: After Elizabeth tells her mother that nobody cares about her, while she sulks on the porch there's a wideshot of the girls playing catch with Holly, then as the camera is dollying out Holly's mother comes into view at the left and she's wearing a sweater, but in the next closeup the sweater has vanished. (00:32:40)
Continuity mistake: When John-Boy finishes the roof repair he carries the ladder and places it beside the tree, then he notices the unlocked padlock on the garage door. In the closeup, the open lock is inserted through the latch facing the right, but in the wideshot the lock is inserted through the latch the opposite way. (00:25:25)
Factual error: The Woman talking with Mamie and Emily about the jams is wearing 1970s large framed glasses. (00:33:15)
