Formula 407 - S1-E12

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.

Continuity mistake: When Steve and Diana are off the coast of Virginia, they share binoculars to watch for three men coming ashore in a rubber boat, and when Steve raises the binoculars to his eyes the lenses are either extremely cloudy or the lens caps are on (it reflects no light), but in the following shot when Steve lowers the binoculars the lenses are perfectly normal. Then when Steve hands Diana the binoculars the lenses are still normal, but in the following shot when Diana lowers them it's once again extremely cloudy or the lens caps are on.
Continuity mistake: In the first two closeups of Steve's two dollar bill, the serial number on the bill is "A16452841A", but when Diana kisses the bill and leaves a lipstick mark, in the next closeup it's actually a different two dollar bill with serial number "A77148841A."

Continuity mistake: When Wonder Woman calls the Dept of Motor Vehicles disguised as General Blankenship, the woman who answers the phone has long polished fingernails, but in the closeup of her going through the file box the fingernails we see are quite short and unpolished (looks like a man's hand).
The New Original Wonder Woman - S1-E1
