Wonder Woman director Patty Jenkins took to Twitter this afternoon to rebut, forcefully, allegations that the DC Universe tentpole starring Gal Gadot is in serious behind-the-scenes trouble. “This is some made up bs [sic] right here. Made up! Produce a source, anyone,” she said, later adding that “zero about the movie we are making has been called a mess by anyone in the know. Fact.”

The context? If you’ve been on Twitter during the past 24 hours, you might have seen the furor over an open letter addressed to Warner Bros Chairman and CEO Kevin Tsujihara, posted anonymously to the website Pajiba by someone claiming to be a former employee of the studio. The focus of the letter is the performance of the studio’s major tentpole films, particularly in light of the controversial 2014 layoffs that, so the letter argues, happened due to the mistakes of people who continue to keep their jobs and/or receive millions in funding from WB.

Blasting Suicide Squad and Batman v Superman: Dawn of Justice in particular, along with several of Warner Bros’ recent unsuccessful films like Point Break and Pan, the letter then drops the claim about Jenkins’ film. “Maybe Wonder Woman wouldn’t be such a mess,” it reads. “Don’t try to hide behind the great trailer. People inside are already confirming it’s another mess. It is almost impressive how you keep rewarding the same producers and executives for making the same mistakes, over and over.”

Bulls-, ah, nonsense, Jenkins said today in a spirited series of tweets.

Given the overwhelmingly negative critical response to Suicide Squad and Batman v Superman, the possibility that Wonder Woman might follow their lead is something Warner Bros no doubt is hugely concerned about. On May 17, the studio put in motion a serious overhaul of its DC Films imprint, a move sources close to the matter have confirmed to Deadline was a direct response to the negative reaction of fans and critics alike to Batman v Superman. Previously existing largely as a production banner, DC Films was established as an official division within Warner Bros, with DC chief content officer Geoff Johns and WB EVP Jon Berg placed in charge.

Wonder Woman wrapped filming on May 9, making it the first of WB’s superhero projects to go into post-production after the establishment of DC Films division. The film is set for release June 2.
