Visible crew/equipment: When Wonder Woman is in the kitchen with the children telling them they should take care of themselves, a crew member's back is visible at the left side of the screen.
Visible crew/equipment: When Wonder Woman arrives at the Diamond H ranch, the housekeeper opens the front door and the reflection of lighting/equipment is visible on the glass. Additionally, there's a prominent flagpole at the front of the house with the Flag of Texas flying high, but the problem is it's being flown upside-down with the red stripe at the top, when it should be the white stripe at the top. Proud Texan JP Hadley would know better.
Visible crew/equipment: After Wonder Woman cautions JP about Lampkin, when JP tells the kids about Maria's apple pie note the open cabinet door over JP's shoulder, presumably to prevent reflections. After Jeff admits to being Lampkin's informer, when JP walks over to Jeff that cabinet door is closed and now we can see the reflections of array lighting/equipment (then when WW walks over both doors are ajar).
Visible crew/equipment: After the children rescue Wonder Woman it cuts to her telling JP and Jeff about it, and when JP tells the kids about Maria's hot apple pie, the actor's tape mark is visible on the rug where Charlie had been standing.
