1 visible crew/equipment mistake in Beebo the God of War - chronological order
Left Behind - S1-E9
Factual error: Ray, Sara, and Kendra are Left Behind in 1958. However, 10 weeks later Sara and Kendra are playing the board game "The Game of Life." The modern version, as seen, didn't come out until 1960 (previously it was called The Checkered Game of Life and doesn't resemble the modern version).
Vandal Savage: Who are you to stand up against me, Vandal Savage, destroyer of empires.
Leonard Snart: Leonard Snart, robber of ATMs.
The Magnificent Eight - S1-E11
Trivia: In the town of Salvation there's a place called "Kubert's Barber Shop." Joseph Kubert was a comic book artist for DC Comics and creator of Hawkman/Carter Hall.
