"WarnerMedia's investigation into the Justice League movie has concluded, and remedial action has been taken," the studio said on Friday, Dec. 11.
Fisher, who played Cyborg in the film, took to Twitter to relay that Warner Bros. had made him aware of their actions.
He added about the studio's message to him, "And this statement (which truly belongs to ALL who participated in the investigation): 'WarnerMedia appreciates you having the courage to come forward and assist the company with creating an inclusive and equitable work environment for it's employees and partners.'"
The star pointed out that he still hopes more work will be done in the aftermath of the investigation.
"There are still conversations that need to be had and resolutions that need to be found," the 33-year-old actor continued. "Thank you all for your support and encouragement on this journey. We are on our way."
This news comes five months after Fisher accused director Joss Whedon of "abusive" behavior that allegedly took place during reshoots helmed by Whedon after credited director Zack Snyder stepped aside following a family tragedy. The actor also accused producers Geoff Johns and Jon Berg of enabling the misconduct.
There were plenty of contentious moments en route to Friday's announcement. In early September, Warner Bros. released a statement claiming that Fisher was not cooperating with the third-party investigation. At the time, Fisher issued his own statement denying this.
Later that month, Justice League co-star Jason Momoa shared an Instagram post in support of Fisher. "Serious stuff went down," the Aquaman actor wrote. "It needs to be investigated and people need to be held accountable. #IStandWithRayFisher."
Fisher recently participated in additional photography for Zack Snyder's Justice League, the four-part HBO Max miniseries premiering in 2021 that is said to fulfill Snyder's initial vision for the project.
