Visible crew/equipment: At the mill, when John tells Buck that Willie Brimmer might be at the Montgomery cabin with Jim-Bob, in the next closeup of John we see a billowy trail of cigarette smoke at the bottom right corner of the screen, but the only people standing there are Elizabeth, John, and Buck, and none are smoking. Presumably, it was someone offscreen smoking too close to the camera (similar to a mistake in 1978's "Halloween"). (00:26:05)
Visible crew/equipment: After Zeb tells the girls that the old dog, Sam, just wants to find a place to die in peace and dignity, when it cuts to John and Willie working inside the mill a crew member (wearing a red, short sleeve shirt) is hiding, toward the right side of the screen. Then after the shot of the girls on the hill, at the start of the next shot as the truck drives up, a bit of camera equipment is visible at the top, right side of the screen. (00:43:00)
