The sequel to Patty Jenkins’s successful first installment to Wonder Woman, officially titled Wonder Woman 1984, was first announced to have a November 1st, 2019 release date, but then was moved back to June 5th, 2020 soon after production of the film was finished.
Wonder Woman 1984 producer Charles Roven went on to explain to ComicBook.com why the date was changed, confirming that the studio wanted to push up the date from the original date because they felt they really needed another tent pole movie in 2019, but then realized that the June date was better for the sequel, as that’s also the month Wonder Woman was released.
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 . 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.
Since the change of date, Todd Phillips’s The Joker starring Joaquin Phoenix as the title character, was then announced by Warner Bros. to have a release date of October 4, 2019, in other words, it looks like The Joker become the replacement for Wonder Woman 1984 in a way for the void that was needed for another DC Comics movie within the year, as Shazam! has the earlier on in the year release of April 5th.
