Factual error: When Walter Goggins fires a LAW at the church from next to the vehicle, the back-blast from the rocket would have shattered the car's windows, and flying glass fragments would likely have injured the occupant. The show depicts neither outcome.
Factual error: Thomas holds the Gendarmerie rank of Capitaine (by which he is frequently addressed by his subordinates), and thus should wear three horizontal silver bars on his epaulettes.

Factual error: The map of the western United States shown during the weather report at the start of the episode shows some states drawn incorrectly. Idaho's entire western border is a straight line, whereas in real life, Oregon has a horn-shaped indentation on its northeastern border that it shares with Idaho. Idaho also looks like a crude staircase, with the southwestern border of Montana going down to central Wyoming, whereas that area in real life is around the northwestern part of Wyoming.
Learning Curve: Part 1 - S1-E5
Factual error: When Pip is blasted back by the plasma jump, he is shown to rotate his body and slow down just before Silver Surfer reaches out and grabs him.

He would continue to float perpetually until he bumped into something with more mass than himself or entered the atmosphere of a planet.
Factual error: A British soldier in 1940 says he was educated at the University of Warwick. The university wasn't founded until 1965.
