Other mistake: The opening credits for season 5 show June coming out of the front door with a pitcher of what looks like iced tea, and calling for Ward, Wally and Beaver who are all working outside. But the door opens by itself as she comes out, and then closes by itself behind her. If the entire family is outside, who opened and closed the door?
Visible crew/equipment: There is a shot of the outside of the tavern (used in several chapters) where Zorro jumps towards Tornado. As the two walk away, a hand can be seen hiding behind the wall where Tornado was standing.
