Zack Snyder wants you to know that Ray Fisher's Cyborg is "the heart" of his Justice League

Ray Fisher was brand new to Hollywood when he made his big-screen debut as Cyborg in 2016's Batman v Superman: Dawn Of Justice, and, had everything gone according to plan, he’d have headlined a Cyborg standalone this year. Unfortunately, Warner Bros. DC franchise has been retooled time and again after films like Justice League and Suicide Squad were rejected by both critics and a good chunk of the superhero-loving populace. Justice League, in particular, had a troubled production history, with original director Zack Snyder being replaced by Avengers’ Joss Whedon in post-production following the death of his daughter. And, nearly three years later, the issues underlying the flop continue to resurface.
On Monday, Fisher tweeted out a video of him at 2017's San Diego Comic-Con, where he praised Whedon as “a great guy” and a “good person to come in and clean up.” In his tweet, however, he declared, “I’d like to take a moment to forcefully retract every bit of this statement.”
Fisher followed up that pointed tweet with another on Wednesday: “Joss Wheadon’s [sic] on-set treatment of the cast and crew of Justice League was gross, abusive, unprofessional, and completely unacceptable.” Fisher adds that Whedon’s behavior was “enabled, in many ways” by Justice League producers Geoff Johns and Jon Berg. (Fisher also took a veiled swipe at Johns in a reply to a tweet from Suicide Squad director David Ayer last month.)
As of this writing, no other cast members have spoken out against Whedon, and the circumstances fueling Fisher’s words remain unclear. What is known, however, is that Cyborg’s arc was deeply impacted by Whedon’s work on the film, which is likely why the actor has been as outspoken as anyone regarding the upcoming “Snyder Cut” of Justice League.
In a 2017 IGN interview, Joe Morton, who played Cyborg’s dad in the film, revealed that a key component of Whedon’s reshoot was to alter the “tone” of the character. “Well, the stuff that I had to do were just really small little bits and pieces, nothing necessarily having to do with tone,” he said. “I know that with Ray [Fisher], the young man who plays Victor, there were some adjustments that they made in terms of the tone of that character.”
