Justice League's Ray Fisher says WarnerMedia launching investigation into workplace behavior of Joss Whedon, more

Justice League actor Ray Fisher's outspoken criticism of the alleged on-set behavior of director Joss Whedon and producers Geoff Johns and Jon Berg on that film looks to have generated some new momentum, according to his latest update on the matter.

Fisher on Thursday took to Twitter to double down on what he claims was the "toxic and abusive work environment created during Justice League reshoots" of the Warner Bros. film, and he says that parent company WarnerMedia has now begun an investigation of its own.

Variety, citing sources inside the company, also confirms that an investigation has been launched but notes that "the investigation is not limited to" Whedon, Johns, and Berg.

Fisher has been reiterating his claims over the summer as soon as Zack Snyder's Justice League got traction at HBO Max. With the winds changing, Fisher has been very public about what he characterized as his negative experience with the creative team that took over after Snyder had to leave the original film. (Whedon, in particular, was allegedly “enabled” by Johns and Berg.)

Here's his latest update:

"After 5 weeks of interviews with various cast/crew, @WarnerMedia has officially launched an independent third-party investigation to get to the heart of the toxic and abusive work environment created during Justice League reshoots," Fisher wrote. "This is a MASSIVE step forward!"

"I believe 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," the actor continued. "Thank you @WarnerMedia and @ATT for making strides to ensure a safer workplace for all!"

While Berg has denied these accusations, Whedon and Johns have not responded to Fisher's claims. Fisher was not on the massive list of announced DC FanDome attendees, though Zack Snyder's Justice League will have a panel where a trailer will be presumably shown. This new version of the film heads to HBO Max sometime in 2021.
