Warner Bros. The INSIDER Summary: "Wonder Woman 2" will be released December 13, 2019. The first movie was released June 2017 and owned the summer box office. It's a bit surprising Warner Bros. didn't give the sequel its coveted mid-July theatrical date where "Harry Potter" and "The Dark Knight" have found huge success. Instead, the sequel will be going up against Disney's "Frozen 2" and has to hope another "Star Wars" movie doesn't get pushed back. We finally have a release date for the "Wonder Woman" sequel, but we're going to have to wait a while. Warner Bros.
