In July, actor Ray Fisher went public with allegations of mistreatment on the set of 2017’s “Justice League”.

Fisher — who played Cyborg in the film — complained that the behaviour of Joss Whedon (who stepped in to complete the movie after director Zack Snyder stepped down partway through filming to deal with a family tragedy) had been “gross, abusive, unprofessional, and completely unacceptable.”

Fisher also claimed that DC Films executive Geoff Johns threatened him when he tried to express his concerns through the appropriate channels.

Following Fisher’s public complaints, Warner Bros. — which produced “Justice League” — announced that an investigation was being mounted to look into Fisher’s concerns.

Fisher responded by thanking the studio, sharing his belief that “this investigation will show that Geoff Johns, Joss Whedon, Jon Berg (and others) grossly abused their power during the uncertainty of AT&T’s merger with Time Warner.”

On Sept. 4, Fisher tweeted that her received a call from DC Films president Walter Hamada “wherein he attempted to throw Joss Whedon and Jon Berg under the bus in hopes that I would relent on Geoff Johns. I will not.”

Following that tweet, Warner Bros. responded with a statement alleging that Fisher has refused to cooperate with the investigation.

“In July, Ray Fisher’s representatives asked DC Films President Walter Hamada to talk to Mr. Fisher about his concerns during the production of ‘Justice League.’ The two had previously spoken when Mr. Hamada asked him to reprise his role as Cyborg in Warner Bros.’ upcoming Flash movie, together with other members of the Justice League,” reads the statement.

“In their July conversation, Mr. Fisher recounted disagreements he’d had with the film’s creative team regarding his portrayal of Cyborg, and complained that his suggested script revisions were not adopted. Mr. Hamada explained that creative differences are a normal part of the production process, and that a film’s writer/director ultimately has to be in charge of these matters. Notably, Mr. Hamada also told Mr. Fisher that he would elevate his concerns to WarnerMedia so they could conduct an investigation. At no time did Mr. Hamada ever ‘throw anyone under the bus,’ as Mr. Fisher has falsely claimed, or render any judgments about the “Justice League” production, in which Mr. Hamada had no involvement, since filming occurred before Mr. Hamada was elevated to his current position,” the statement continues.

“While Mr. Fisher never alleged any actionable misconduct against him, WarnerMedia nonetheless initiated an investigation into the concerns he’d raised about his character’s portrayal. Still not satisfied, Mr. Fisher insisted that WarnerMedia hire an independent third party investigator. This investigator has attempted multiple times to meet with Mr. Fisher to discuss his concerns but, to date, Mr. Fisher has declined to speak to the investigator. Warner Bros. remains committed to accountability and to the well-being of every cast and crew member on each of its productions. It also remains committed to investigating any specific and credible allegation of misconduct, which thus far Mr. Fisher has failed to provide,” the studio’s statement concludes.

Fisher subsequently responded with a pair of tweets disputing the studio’s claim that he was uncooperative by sharing an email in which he questions the independence of the investigation. Fisher also slammed Warner Bros. for what he described as a “desperate and scattershot attempt to discredit me to continue protecting those in power.”

In his second tweet, Fisher reminded that he had previously “made it clear to the world… that I would be vetting the investigator to ensure a fair and protected process for all witnesses.”
