Just when you thought the cast of FX and Ryan Murphy mouthful American Crime Story: The People v. O.J. Simpson couldn’t get more outlandish, the marquee grows even bigger. Star Trek star and recent Mad Men guest Bruce Greenwood will suit up for the historic crime drama, among several other new additions to the cast.

Per FX’s official announcement, Greenwood will play the role of Gil Garcetti, the Los Angeles County District Attorney who prosecuted Simpson for the murder of his ex-wife Nicole Brown Simpson and Ronald Goldman. Provided the series doesn’t end up swallowing Hollywood whole, Crime Story has also added Steven Pasquale as Mark Fuhrman, Sterling K. Brown as Christopher Darden, Malcolm-Jamal Warner as Al Cowlings, Evan Handler as Alan Dershowitz and Cheryl Ladd as Linell Shapiro.

The 10-episode miniseries follows Jeffrey Toobin book The Run of His Life: The People v. O.J. Simpson, with episodes written by Scott Alexander & Larry Karaszewski, and directed by Ryan Murphy. Produced by Murphy, Nina Jacobson, Brad Simpson, Brad Falchuk and Dante Di Loretto, so reads the official synopsis for the new series, which begins production this year:

‘American Crime Story: The People v. O.J. Simpson’ is a look at the O.J. Simpson trial told from the perspective of the lawyers that explores the chaotic behind-the-scenes dealings and maneuvering on both sides of the court, and how a combination of prosecution confidence, defense wiliness, and the LAPD’s history with the city’s African-American community gave a jury what it needed: reasonable doubt.

The bevy of newcomers join a cast that thus far includes Selma Blair as Kris Jenner, Billy Magnussen as Kato Kaelin, Jordana Brewster as Denise Brown, Kenneth Choi as Judge Ito, Connie Britton as Faye Resnick, Courtney B. Vance as Johnny Cochran, John Travolta as Robert Shapiro, David Schwimmer as lawyer Robert Kardashian, Cuba Gooding Jr. as the titular criminal, and Sarah Paulson as prosecuting attorney Marcia Clark. Keeping to the American Horror Story model, subsequent seasons will follow another headline-making real-world crime, though it’s unclear if the series would reuse cast members, like its predecessor.

Production has already begun, spilling out set photos from California, but who else should join FX’s American Crime Story: The People v. O.J. Simpson before its 2016 premiere?
