Joss Whedon wasn’t allowed to be alone with Michelle Trachtenberg on ‘Buffy’ set, actress says

Joss Whedon was barred from being alone with Michelle Trachtenberg on the set of his show, “Buffy the Vampire Slayer,” according to the actress.

Trachtenberg, 35, who as a teen played Dawn Summers from 2000 to 2003 on the series Whedon created, expanded on her previous allegations against the 56-year-old “Avengers” director in a Thursday Instagram post.

“The last. Comment I will make on this. Was. There was a rule. Saying. He’s not allowed in a room alone with Michelle again,” the “Gossip Girl” actress commented on her earlier post.

Originally, Trachtenberg had reposted a Wednesday statement from Buffy herself, Sarah Michelle Gellar: “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.”

Gellar, 43, added: “I stand with all survivors of abuse and am proud of them for speaking out.”

In her repost, Trachtenberg wrote: “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 behavior....very. Not. Appropriate. So now. People know. What Joss. Did.”

Both actress’ remarks followed that of Charisma Carpenter, 50, who accused the Oscar-nominated Whedon of having “abused his power on numerous occasions” on the set of both “Buffy” and the “Angel” spinoff.

Carpenter accused the filmmaker of “being casually cruel.”

“He was mean and biting, disparaging about others openly, and often played favorites, pitting people against one another to compete and vie for his intention and approval,” she alleged, referencing an instance in which he reportedly chose to “interrogate and berate” the actress for a rosary tattoo she got “to help me feel more spiritually grounded in an increasingly volatile work climate.”
