While hit TV show <em>Buffy the Vampire Slayer</em> was known for its on-screen violence, the toxic abuse that was allegedly taking place off the camera is only just being publicly discovered. Charisma Carpenter, who played Cordelia Chase in <em>Buffy</em> and spin-off series <em>Angel</em>, posted on Twitter a lengthy statement accusing show creator Joss Whedon of abusive behaviour on set on Wednesday, February 10 . "For nearly two decades, I have held my tongue and even made excuses for certain events that traumatise me to this day," the actress wrote in a post that's been liked more than 150,000 times. She alleged Whedon "abused his power on numerous occasions" while she worked on both TV series, and accuses him of "casually cruel" behaviour, which included threatening to fire her, calling her "fat" when she was four months pregnant, asking her if she was going to "keep" her baby, mocking her for her religious beliefs, and then "unceremoniously" firing her after she gave birth. "Back then, I felt powerless and alone," she writes, while also admitting she still sought his validation and even publicly said she'd work with him again. "Only recently, after years of therapy and a wake-up call from the Time's Up movement, do I understand the complexities of this demoralised thinking." This comes after actor Ray Fisher accused the director last summer of "gross, abusive, unprofessional, and completely unacceptable" behaviour on the set of 2017 film <em>Justice League</em>. This was the subject of a lengthy investigation by WarnerMedia in 2020. "When [Fisher] publicly accused Joss of abusive and unprofessional behaviour ... it gutted me," Carpenter continued. "Joss has a history of being casually cruel. He has created hostile and toxic work environments since his early career." She used the hashtag #IStandbyRayFisher with her posts. Carpenter said she participated in the WarnerMedia investigation and decided to come forward after Fisher announced he was no longer going to play <em>Justice League</em> character Cyborg in the coming movie <em>The Flash</em>. "His firing ... was the last straw for me," she wrote. "It troubles and saddens me that in 2021 professionals STILL have to choose between whistleblowing in the workplace and job security." A number of <em>Buffy</em> stars have since spoken out in support of Carpenter, including Sarah Michelle Gellar, who played the titular character in the series. "While I am proud to have my name associated with Buffy Summers, I don't want to be forever associated with the name Joss Whedon," she wrote in a post on Instagram to her 3.5 million followers. "I am more focused on raising my family and surviving a pandemic currently, so I will not be making any further statements at this time. "But I stand with all survivors of abuse and am proud of them for speaking out." Actress Michelle Trachtenberg, who played Buffy's sister Dawn, reposted Gellar's statement, writing in the caption: "Thank you @sarahmgellar for saying this. I am brave enough now as a 35 year old woman....To repost this. Because. This must. Be known. As a teenager. With his not appropriate behaviour....very. Not. Appropriate. So now. People know. What Joss. Did." Amber Benson, who played witch Tara, also spoke up. "Buffy was a toxic environment and it starts at the top," she wrote in a post on Twitter. "@AllCharisma is speaking truth and I support her 100 per cent. There was a lot of damage done during that time and many of us are still processing it twenty plus years later." Clare Kramer, who took on the role of baddie Glory in season 5 of the show, wrote: "For what it’s worth, I believe and stand with @allcharisma, @ray8fisher, @amber_benson and others who have the strength to come forward with their truth. A lot of this industry needs a reset." Fisher also commented on Carpenter's accusation, saying she is "one of the bravest people I know". "I am forever grateful for her courage and for her lending her voice to the <em>Justice League</em> investigation. Read her truth. Share her truth. Protect her at all costs. 'It is time.'" Whedon has yet to respond to the new allegations.
