Amanda Seyfried has no regrets about sparring with Elizabeth Holmes' partner Billy Evans in that jaw-dropping scene

• Amanda Seyfried gave her first detailed account of starring in "You Can See Everything."
• Seyfried spoke to Rolling Stone about sparring with Billy Evans in one of the movie's climactic scenes.
• "There was no reason for him to get that aggressive," Seyfried said, referring to Evans, who is Elizabeth Holmes' partner.

The wait is over: Amanda Seyfried has finally spoken out about appearing in "You Can See Everything."

In an interview with Rolling Stone released on Wednesday, Seyfried, along with directors Nathan Fielder and Lance Oppenheim, spoke about how "The Dropout" star got involved in the hit Elizabeth Holmes documentary.

It began harmlessly enough, when Seyfried's friend Emma Stone connected her with Fielder, who asked if she'd look over the interview footage they'd shot with Elizabeth Holmes. After sharing her thoughts, Seyfried's involvement eventually expanded to include her filming reenactments playing Holmes, and, in one shocking moment, traveling with Fielder to have dinner at the home of Holmes' partner, Billy Evans.

The scene is one of the doc's most climactic and surreal moments, as Seyfried ends up sparring with Evans at the dinner table.

Seyfried admits in the Rolling Stone interview that she already had "negative feelings" toward Evans after seeing Fielder's footage. But she said things "only got worse" after meeting him.

"I am sitting there with her children and cuddling with her dog! While she's in prison!" Seyfried said of being in Evans' home while Holmes is in prison. Holmes even calls from prison while Seyfried and Fielder are there.

"Someone asked me if that was real, if that was really her on the phone. And I'm like, 'It's a documentary. Who else would it be?'" she said.

Things quickly went downhill during dinner when Evans insulted Seyfried's acting and the two sparred over Seyfried's comments about Charlie Kirk. Seyfried told Rolling Stone the moment really was as intense as it's portrayed onscreen.

"There was no reason for him to get that aggressive," Seyfried recalled. "That's the word I'm going to use, as it's more diplomatic. If my jaw wasn't obviously on the floor, you could tell, like, it had come unhinged. I don't want to provoke him, but at this point, it's kind of like, the gloves are off. Because this guy has disrespected me in such a way that I was like, 'Oh, I don't think so, buddy.'"

Seyfried said she has no regrets about how she handled the argument.

"I was in the frame of mind where I'm like, 'OK, this guy is disrespectful, and I'm here in his home, I'm gonna argue this because I actually have a pretty solid stance on things. I don't like the way he's using this human being, his wife — the person he says he's "building monuments of love' to — as a tool. Maybe he does respect her, but he's behaving like he does not respect her. And not only am I protective of myself, I'm just trying to set the record straight in a way where I'm trying to defend myself, too, while maintaining some kind of rapport with him, so I can stay and he doesn't kick us out, you know?"

Billy Evans did not respond to a request for comment.

"You Can See Everything" is in theaters now.
