RELATED: This TV Star Left His Show After “Terrorizing the Set,” Producer Says One Tree Hill ran for nine seasons, from 2003 to 2012. And while the open letter about Schwahn (pictured above center) claims that his alleged misconduct was common knowledge on the set, his women colleagues didn’t come forward until a few years after the series finale. The cast and crew who signed the letter were motivated to speak out in support and solidarity after one of the show’s writers, Audrey Wauchope, made harassment accusations against Schwahn (though, without naming him) on her personal Twitter account. The letter claims that women working on the show were “manipulated psychologically and emotionally” by Schwahn, “were put in positions where [they] felt physically unsafe,” and were discouraged from coming forward because it “would result in our show being canceled and hundreds of lovely, qualified, hard-working, and talented people losing their jobs.” Some detailed the harassment and misconduct they experienced to Variety, including stars Hilarie Burton, who claimed that Schwahn assaulted her on several occasions, and Danneel Ackles, who recounted instances in which Schwahn came uninvited to her hotel room and her home and demanded to see her. Male and female writers reported Schwahn making inappropriate, demeaning jokes, as well as sexual advances, in the writers room. At the time that the accusations because public, Schwahn was working on another show he created, The Royals, an E! drama revolving around a fictional royal family. A few days after the open letter was published, the companies behind the show issued a statement that Schwahn had been suspended to allow for an investigation. About a month later, Lionsgate circulated another statement announcing, “We have concluded our investigation and Mark will not be returning to The Royals.“ae0fcc31ae342fd3a1346ebb1f342fcb Amid the suspension, Royals actor Alexandra Park responded on social media. “I am devastated to admit to myself, to my colleagues, and to this industry that I too, have been exposed to this reprehensible behavior,” she tweeted, as reported by Variety. Another open letter, this time from the women working on Schwahn’s new show, quickly followed. It read, in part, “It became all too apparent reading [the One Tree Hill cast and crew’s] statement earlier this week that the betrayal and anger so many of us had experienced during our time on The Royals is not exclusively ours. And we were angry then, and we are angry now.” Schwahn declined to comment on any of the accusations or his firing at the time, and he hasn’t worked on any shows or movies since The Royals. Still, it appears that there’s more to talk about. Another conversation about Schwahn ensued when Craig Sheffer, who played Uncle Keith, was on the April 4 episode of the Drama Queens podcast, hosted by One Tree Hill co-stars Burton, Bush, and Bethany Joy Lenz. Scheffer’s character was shockingly killed off early on in the series, and the actor claimed that Schwahn blindsided him with that news after ensuring him that his position was safe. “I go, ‘OK, so I’m dead? Does that mean I don’t get paid anymore?’” Scheffer said, recalling a phone call he received from the showrunner. “He was like, ‘Yeah.’ I was like, ‘Dude, you told me.’ Not only was it cheesy, but the way it was handled. You don’t call me and talk to me about it?” Scheffer also said that he felt like Schwahn nitpicked his personal needs, like requiring time off to see his daughter, and his appearance, because for him, “it was so about control.” “‘We want your hair combed back, we want you shaved, we want this.’ It got to a point where they’re calling my agent like, ‘If this power struggle is going to continue, we’re just going to get rid of him,’” the actor explained. “That kind of stuff, they break down your soul.” RELATED: For more entertainment news sent right to your inbox, sign up for our daily newsletter. Bush (pictured above left) corroborated Scheffer’s claim that Schwahn was fixated on controlling the appearance of the actors in the show, having had her own issues in that area. When she decided to change her hair between seasons, Schwahn “lost his mind on [her].” “You know what he said to me?” Bush continued. “A grown man who was my boss. I was 22, 23. He goes, ‘Who the [expletive] told you you could cut bangs? You know who had bangs? All the [expletive] cheerleaders in high school who never wanted to have sex with me.’ I was like, ‘What’s happening?’ Craig, it was so controlling and gross and misogynistic and creepy for us. He’d yell at Hilarie and I if we put our hair in ponytails during cheer practice.” RELATED: This TV Star Says She Felt “Intimidated” Into Silence After On-Set Accident.
