The Journal - S8-E7
Continuity mistake: In this episode Olivia states that she conceived one month after getting married. Olivia asks John if he remembers that summer when just the two of them went camping up on the mountain, and they both recall that it was their one month anniversary after eloping. Olivia also says that she knew later that night, "That there's some kind of miracle happening inside me," and even felt that it was a boy - John-Boy, their eldest child. The problem is, in 8x1 "The Homefront," when Cindy joins Olivia in the garden, Cindy asks, "How long was it before you knew you were expecting John-Boy?" and Olivia replies, "About two years, but everybody is different..." (00:23:10)

Visible crew/equipment: While driving to the fair John-Boy tells Oscar it's the next turn on the right, then it cuts to two overhead shots of the fairgrounds, and in that second overhead shot we can see the crew's Panavision camera at the bottom right corner of the screen. As an aside, Panavision was founded in 1953. (00:28:40)
Visible crew/equipment: When Oscar and the Baldwin sisters get up to leave after their visit with the Walton family, they walk to the front door and we can see set equipment at the right side of the screen. Then when they get into the vehicle and start to drive away, the reflections of some crew members are visible on the vehicle windows. (00:10:20)
Visible crew/equipment: After Zeb retrieves the misplaced perfume from the Baldwin sisters, when he meets up with John-Boy on the road, the reflections of crew members are visible on the truck's windshield when John-Boy arrives, and also when he backs up the truck. (00:36:40)
Visible crew/equipment: When John and Esther go to the Baldwin house in search of Zeb, while John leans on the vehicle door talking to Esther, in the closeups the shadow of the moving boom mic is visible at the back of the truck. (00:17:10)
Visible crew/equipment: After all the children leave for school, the man from the electric company goes to the back of the Walton house to turn the power off, then while Olivia, Esther, and Zeb stand near the home John gets into the truck, and in the next shot of John in the truck we can see a crew member (who appears to be shirtless) through the windshield, walking around inside the barn (this cannot be anyone else other than a crew member). (00:05:10)
Visible crew/equipment: When Jody asks John-Boy about Chateau d'If in The Count of Monte Cristo, Harley drives up in the automobile he fixed, and in the two shots facing Jody by himself, the shadow of the moving boom mic is visible on the wood beam beside Jody. (00:26:20)
Visible crew/equipment: After John-Boy reads from the Count of Monte Cristo, everyone climbs down from the treehouse, and as Ben, Elizabeth, and Jim-Bob walks toward the Walton house, we can see a balding crew member wearing white pants, at the left side of the screen. (00:25:15)
Visible crew/equipment: After Olivia and Esther talk to Verdie about Harley, while they're all busy in the kitchen with the peaches, when it cuts to Harley walking we can see set equipment at the right side of the screen. (00:21:30)
Visible crew/equipment: When Verdie shows Harley the overalls for Jody, the reflection of the boom pole and mic are visible on the vehicle surface in the overhead shots. (00:19:25)
Visible crew/equipment: After Harley tells Verdie that he's an auto mechanic but things are slow, when Jim-Bob and Elizabeth rush over to John-Boy to tell him they can keep the peach tree, the shadow of the moving boom pole and mic is visible on the ground beside Jim-Bob, at the right side of the screen. (00:06:35)
Factual error: When Mary Ellen brings G.W. into the woods to practice dancing together, she opens up a magazine and shows him a movie still of Fred Astaire and Ginger Rogers. The problem is the photo is a still from Fred and Ginger's dance in the movie "Swing Time" (at 00:28:00 within that movie) which premiered August 1936 (and was filmed that year), but this episode takes place more than two years prior, in early 1934. (00:59:20)
Continuity mistake: When Olivia asks John to go with them to Sunday services, in the wideshots Erin is sitting on the arm chair and Jim-Bob is rocking away in the rocking chair, but in the few shots facing John or Zeb we see the rocking chair and arm chair are empty. (00:04:10)
Visible crew/equipment: When the Baldwin sisters drive up to the Walton house with a gift, the reflections of location lighting and a few crew members are visible on their car's windows. (01:07:40)
Factual error: After Olivia realises she has polio, when John goes downstairs the radio is on and we hear an excerpt from President Roosevelt's fireside chat about upcoming Labor Day. The problem is this aired on the radio right before Labor Day in 1936, but Olivia contracts polio very early 1934. (00:22:35)
Continuity mistake: The Baldwin sisters buy Olivia a wooden wheelchair, and when Zeb brings it into the bedroom the camera tilts downward and we see Zeb's legs behind the chair. Later, after Mary Ellen and G.W. dance for Olivia it cuts to a closeup of the wheelchair, but it's actually the earlier shot because we still see Zeb's legs and he's not even in the room. (01:09:10 - 01:14:20)
Visible crew/equipment: While Mary Ellen walks home with G.W. after the Sunday services they're alone, and when G.W. tells her, "People learn how to dance," right at the start of the next shot we can see the blue shirt of a crew member at the lower left side of the screen. (00:08:30)
