If they're still developing a Flash feature, that would suggest they're planning to have separate TV and movie continuities, then. I guess that rules out what I was thinking, that maybe the emergence of superpowers could be an aftereffect of the introduction of Kryptonian technology to the world. Maybe some remnants of it were scattered around the world and affect people in strange ways, or the government/military tries to reverse-engineer it and experiments on people, or whatever. Kind of like how the MCU is using Asgardian tech as the justification for a lot of its superscience. But if the TV and movie universes are separate, I guess that won't work.
I wonder, though, if Amazon
will be part of the DCCWverse, as it were, if it ever gets off the ground.
