It's safe to say that
Wonder Woman 1984 is currently the most anticipated film on DC's upcoming slate. Patty Jenkins' predecessor, which was released in 2017, garnered critical acclaim from the majority of critics as well as all four quadrants. We knew a sequel would be coming eventually, it was just a matter of when.
Holding a November 2019 release date, it was announced last year that the film would be moved all the way to June 5, 2020. With the sequel already mid-production, this was an unprecedented move from the studio, which seemed keen on a fast tracked-product.
When asked about the movie being pushed back by Collider,
Justice League and
Wonder Woman producer Charles Roven had this to say:
We always wanted the date that we are on right now. The studio felt that until their slate for the year before came together—and they had an amazing end of 2018—that they needed to have a big what I call aircraft carrier, a “tentpole”, in [2019]. We had a very rushed pre-production because Patty also did the TNT show and we had a very rushed post-production schedule in order to make the date that we were on, which was November 1, 2019. We were doing it because the studio said they really needed it, and then at a certain point they came to us and they said, ‘You know what, you guys are right. Let’s go back to the month that you guys released [Wonder Woman] in, and take the extra time.
Thankfully, the studio was taking note of the requests of their creators, which is another example of DC's newfound reliance on creatives instead of strategic profit. Take note, inexperienced cinematic universes.
