Ray Fisher's very public battle between himself and Warner Bros. / DC Films has moved into a new chapter from last night.

In a tweet sent yesterday evening, Fisher pretty much ended his tenure as Cyborg in the 'Justice League' franchise by saying that he will no longer participate in any production by DC Films with studio chief Walter Hamada in charge.

"Walter Hamada is the most dangerous kind of enabler. His lies, and WB PR’s failed Sept 4th hit-piece, sought to undermine the very real issues of the Justice League investigation," Fisher tweeted above a New York Times article about DC Films' upcoming plans involving HBO Max and cinema releases.

That plan, in a nutshell, involves DC Films releasing up to four movies per year, with the more expensive efforts going to theatres while the less-expensive ones go to HBO Max directly. Not only that, more TV spin-offs will be in the mix. So far, two movies - 'The Batman', and 'The Suicide Squad' - already have themselves a spin-off on the streaming service.

It's not yet clear if Fisher's character, Cyborg, had any role to play in these plans. Cyborg was apparently due to appear in 'The Flash', the standalone movie directed by Andy Muscietti and starring Ezra Miller in the title role. However, given Fisher's latest comments, his involvement now seems unlikely.

Fisher has, in the past, accused Joss Whedon - who took over from Zack Snyder as director on 'Justice League' - over gross misconduct on the set. A third-party investigation took place at Fisher's urging and concluded earlier this month, with findings from that investigation not made public. WarnerMedia gave a short statement at the time, claiming that "remedial action" had been taken.
