I found this oddity today. A failed pilot for a Wonder Woman show in 1967.
The concept sounds very Grant Morrison.
Even before the 1970s, producers tried to bring the character to TV—and it certainly would’ve been one of the weirdest takes on the character if it ever advanced beyond the pitch stage. Who’s Afraid of Diana Prince? only exists as a four-minute test scene, and bizarrely imagined Diana, played by Ellie Wood Walker, as a housewife who could look in a mirror and see her reflection as Wonder Woman, played by Linda Harrison—with the implication that Diana was basically going insane and Wonder Woman didn’t really exist. Weird.
