Visible crew/equipment: When John-Boy asks Esther to help him with his story she replies that she'll tell him about it later, and in the next shot of Liv and John, filming equipment is visible at the right side of the screen. (00:04:15)
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 John-Boy quietly leaves his home to search for his sister it cuts to a long shot of Jamie and Mary Ellen, and at the lower right side of the screen we can see a crew member wearing eyeglasses moving around, with equipment in front of him. (00:34:50)
Revealing mistake: When Maryellen runs into John-Boy's arms (after running away) Richard Thomas (John-Boy) breaks character as he looks into Judy's (Maryellen) eyes, by swallowing hard. Like a guy would do, when he's close to an attractive girl. Then later covers his groin with the cast, when John and the kids check up on him. The two young actors playing Jon-boy and Maryellen crushed on each other behind the scenes.
