Other mistake: The security guard alerts Batman about Barry Allen's arrival pushing a button on his phone. The date on the phone says it's Friday 20th Jan, which is coherent with the year (2017) this version of the movie is set in, but too early for the K-pop "As if it's your last" music video playing in Flash's lair (it was a summer release).

Other mistake: Five people are walking in the forest to find a new place to stay. One person is not carrying anything. A child is carrying a camp lantern. One man is carrying a medium size duffel pack. Of the remaining two are one leading an injured man with a bandage on his eyes. No packs. When they make camp the have a large tent, a camp stove, a pot, and a sleeping bag, even fishing poles and gear. No way would all that fit in the one bag.

Other mistake: Towards the end of the movie when Spencer is riding the motorcycle to the top of the jaguar statue, he throws the grappling hook and swings on the rope. When Martha hands him the jewel as she falls, the rope he was swinging on disappears.
