Justice League actor Ray Fisher accused director Joss Whedon of treating the cast in a “gross, abusive, unprofessional, and completely unacceptable” manner on the set of the 2017 film in a tweet Wednesday. Whedon had taken over for director Zack Snyder to complete additional photography for the film after a death in Snyder’s family led him to leave the project. Earlier in the week, Fisher had shared a video of the 2017 San Diego Comic Con in which he called Whedon “a great guy” and a good choice of a replacement, captioning the video, “I’d like to take a moment to forcefully retract every bit of this statement.”
