American Crime Story season 4 to tackle Monica Lewinsky scandal

Plus, one cast member has already been confirmed - and, yes, it's the one person you're thinking of right now

Though Ryan Murphy has remained typically tight-lipped about American Horror Story's future, he's been far more liberal when it comes to American Crime Story.

We'll have to wait until next year for the show's second season, focused on the aftermath of Hurricane Katrina, and presumably even longer for season 3's look at the murder of designer Gianni Versace.

However, Murphy has already confirmed that season 4 will focus on the Monica Lewinsky sex scandal, following news last month that he'd optioned the rights to Jeffrey Tobin's book on the subject, A Vast Conspiracy: The Real Sex Scandal That Nearly Brought Down A President.

The book details the events which led up to the trial to impeach President Bill Clinton, the second such vote in American history, though he was eventually acquitted of all charges.

There's a focus, as well, on the various participants in the scandal; including Linda Tripp, the US civil servant who secretly recorded Lewinsky's confidential phone calls about her relationship with the President.

"It's a very interesting book," Murphy told E! News. "It's not really about Hillary Clinton. That book is about the rise of a certain segment of a right-ring group of people who despised the Clintons and used three women, Paula Jones, Monica Lewinsky and Linda Tripp to try and tear him down. The Toobin book is amazing. And there are a lot of bizarre crimes within that book that you can highlight."

"But the show isn't really about Hillary Clinton, it really is about the other women. In fact, we might be doing the Clintons with hand puppets [laughs], I don't know. We're more focused on the mechanizations behind the scenes to try and get [Bill Clinton] impeached."

Murphy even confirmed his longtime collaborator Sarah Paulson - who's featured in every season of American Horror Story, American Crime Story, and the upcoming Feud - will indeed be joining the cast in an unspecified role.

"Sarah will be in it but she won't be playing Hillary [Clinton]," Murphy added. "That's earmarked for talks with somebody else. We're casting that now. I can't say what Sarah is playing, but it starts shooting at the end of this year."
