Warner Bros. Co-President of Production Jon Berg has responded to recent accusations made by Justice League actor Ray Fisher, who said that Berg and Geoff Johns allowed Joss Whedon's supposed abusive on-set behavior to occur.

In response to the comments made by Fisher, Berg said it was "categorically untrue that we enabled any unprofessional behavior," according to a statement published in Variety. He went on to say, "I remember [Fisher] being upset that we wanted him to say ‘Booyaa,’ which is a well known saying of Cyborg in the animated series." Additionally, it was mentioned in the article that Whedon himself had no comment.

In his initial Tweet, Fisher said Whedon's treatment of Justice League's cast and crew "gross, abusive, unprofessional, and completely unacceptable." None of the other main cast members from Justice League have spoken out about Fisher's comments.

Fisher's character in Justice League, Cyborg/Victor Stone, was meant to play a larger role in the film, according to Zack Snyder. However, many of Cyborg's scenes were eventually removed when Whedon took over as director. Many fans are hoping that Zack Snyder's Justice League, which is set to hit HBO Max in 2021, will feature the additional Cyborg scenes that have been teased.
