Justice League star Ray Fisher is sounding off on how Joss Whedon treated the cast during filming the DCEU project.

Fisher took to Twitter to tell his audience how Whedon mistreated him and the people on the Justice League. “Joss [Whedon’s] on-set treatment of the cast and crew of Justice League was gross, abusive, unprofessional, and completely unacceptable,” he wrote. “He was enabled, in many ways, by Geoff Johns and Jon Berg. Accountability>Entertainment.”

Whedon has been on Fisher’s radar since June 29, when he tweeted that he wanted to “forcefully retract every bit” of his 2017 Comic-Con statement, in which he described Whedon as a “great guy.”

Whedon took over filming Justice League after Zack Snyder left the film because of a family emergency. Snyder has since come back to the project and is working on his cut of Justice League, which will debut on HBO Max next year.

This isn’t the first time Whedon has been called out for being less-than-stellar. In 2017, Whedon’s ex-wife Kai Cole lambasted Whedon for being a “hypocrite preaching feminist ideals.” In the guest post for The Wrap, Cole revealed Whedon had numerous affairs during their 15-year marriage and caused Cole to have “Complex PTSD.”
