Other mistake: After John-Boy leaves, in the last scene we hear Jim-Bob ask about the magazines, but subtitles claim it is Ben who asks, then as we hear Jason answer the queston, the subtitles tell us it is Jim-Bob who answers. (00:47:00)
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)
Revealing mistake: While John-Boy is in his old bedroom with John Curtis, having a heart-to-heart conversation with the baby, in all the wideshots from behind the crib the edge of the set is visible at the right side of the screen. (00:21:20)
