Days later, the studio hired Dave Callaham to co-write the film's script with Jenkins and Johns. On March 9, 2018, Kristen Wiig was confirmed to play Cheetah, the villain of the film. Later that month, it was announced that Pedro Pascal would have a key role in the film. In May 2018, long-time DCEU producer Zack Snyder confirmed on social media platform Vero that he, along with wife Deborah Snyder, will serve as producers on the Wonder Woman sequel. In June 2018, the title of the film was announced to be Wonder Woman 1984. A third film was announced in January 2019 to be taking place in the present.
