The only film in what I adamantly do not call the "DC Extended Universe" (although I guess I just did) that people universally like is Wonder Woman, but it appears that the sequel Wonder Woman 1984 will take a bit longer to reach theaters. Originally slated for a November 1, 2019 release, the movie will now be a summer film slated for June 5, 2020.
Wonder Woman herself Gal Gadot tweeted out the news earlier today.
Super excited to announce that, thanks to the changing landscape, we are able to put Wonder Woman back to its rightful home. June 5, 2020. Be there or be square!!!— Gal Gadot (@GalGadot) October 22, 2018
Per THR, Warner Bros. President of Domestic Distribution Jeff Goldstein expanded on Gadot's characterization of the new date as "its rightful home," saying:
"We had tremendous success releasing the first Wonder Woman film during the summer so when we saw an opportunity to take advantage of the changing competitive landscape, we did. This move lands the film exactly where it belongs."
No apparent creative differences or crazy film-changing reshoots like Fox's The New Mutants, but rather a strategy to draw an audience during a more opportune time like Fox's other thing Dark Phoenix. Seeing how the first film's June 2017 release, plus the positive reception and word of mouth, led to a massive box office haul, it is believable that this is a move to possibly make lightning strike twice.
