Other mistake: When the wild hawk flies over and soon lands on the green painted chicken box, not only are different birds of prey shown in these shots, their flight feathers are also intact.

Visible crew/equipment: After Jim-Bob gets home he and John talk for a bit, then just as Jim-Bob walks behind his father and says, "I hope you find your fishing pole," the arm of a crew member is visible at the right side of the screen. (00:08:10)

Visible crew/equipment: When Jim-Bob is in his car trying to get it going, in the last shot as he successfully drives away from The House, the reflector screen is visible at the left side of the screen, and the shadow of a crew member with filming equipment is also seen at the bottom, left side of the screen. (01:10:25)

Visible crew/equipment: After Mary Ellen leaves in the van to visit Curt at Fort Lee, when it cuts to Olivia with the baby, the shadow of the boom mic dips into view just as John sits down. (00:33:35)
Factual error: After Jason tells Olivia that he's giving up playing his music because he doesn't think he has a choice, when it cuts to the exterior shot of the rooming house, the vehicle parked in front is modern. The same type of thing happens later, when John rescues Pip from the airfield there are modern vehicles, etc, on the street in the background. (00:34:30 - 01:29:30)

The Return - S6-E20
Factual error: Right before the scene with John-Boy and Daisy at the restaurant, there's a shot of Times Square, and two of the marquees advertise the 1946 movie "The Jolson Story," and the 1946 movie "The Best Years of Our Lives," and also reads "Picture of the Year" which it won at the 1947 Academy Awards, but this episode takes place in 1940. (00:05:30)
The Return - S6-E20
Factual error: The year is 1940, and in the opening shot (as the name Richard Thomas appears on the screen) we have a view of Lower Manhattan as seen from the East River below the Brooklyn Bridge, but the problem is some of the buildings we see did not exist in 1940, such as One Chase Manhattan Plaza, which did not begin construction until 1957.
