Patty Jenkins has confirmed that Wonder Woman 2 will be another period piece, this time set in the 1980s. Although most of the DCEU has been set in a chronological order, Wonder Woman has been the rare exception. Though Wonder Woman first appeared in the film franchise during Batman V Superman, the majority of her debut movie was set during World War I, the earliest that any superhero movie story has been set.
There was heavy speculation that Wonder Woman 2 would follow suit, given the ending of Diana’s debut. Wonder Woman has a rather bittersweet ending with Diana mourning the death of Steve Trevor but still resolving to help humanity and be a part of the world. This was at odds with Diana’s story in both BvS and Justice League, where she was re-entering the world after a long absence. It appears that among many other things, Wonder Woman 2 will answer the lingering mystery of Diana’s disappearance.
