“Glee” alum Darren Criss has landed a major role in Ryan Murphy’s FX TV series, “American Crime Story.”

According to TV Line, the actor will play the role of a serial killer named Andrew Cunanan in the “Versace” installment of the series. Cunanan is the one responsible for killing famed designer Gianni Versace. Edgar Ramirez has been cast to play the lead role.

“American Crime Story” Season 3 will have a total of 10 episodes, and they will chronicle the 1997 assassination of the designer in his own home in Miami Beach. A week following his death, his killer decides to take his own life. The entire season will be based on the book, “Vulgar Favors,” written by Vanity Fair writer Maureen Orth.

As of late, the role of Gianni’s sister, Donatella, has not yet been cast. Previously, there were rumors that Lady Gaga will be giving life to the character, but the creators of the series debunked this, saying that she won’t be part of the third season. Gaga and Murphy worked together in “American Horror Story: Hotel” in the past.

No other cast member has been confirmed to appear in “Versace,” but actress Annett Benning has signed on to star in another “American Crime Story” installment, “Katrina.” She will be playing the role of Louisiana Governor Kathleen Blanco. Other actors who will be part of the series, but also potentially in different installments, include Courtney B. Vance, Sarah Paulson, Cuba Gooding Jr. and Sterling K. Brown.

Meanwhile, Murphy will also be taking on Monica Lewinski’s scandal, according to E! News. Paulson will most likely be part of the installment, but she will not be playing the role of Hillary Clinton.

“American Crime Story: Versace” will premiere on FX sometime next year.
