So this is much less about the actual crime itself, as the story takes place after their murders (the court trial that followed), and there will be no flashbacks.
Cuba Gooding Jr. plays O.J., while Sarah Paulson is prosecutor Marcia Clark, Courtney B. Vance plays the late Johnny Cochran, David Schwimmer is Robert Kardashian, John Travolta plays Robert Shapiro, and Billy Magnussen as Kato Kaelin.
Malcolm-Jamal Warner is A.C. Cowlings, the former pro football player and friend of the defendant, who was also the driver of the white Ford Bronco in the infamous televised police chase; Selma Blair is Kris Kardashian and Connie Britton is Faye Resnick.
The real O.J. Simpson is not involved in the series in any way, nor will he benefit financially from it.
FX has now released a first poster for the upcoming series, which is embedded above.
No full trailer yet, just a bunch of teasers, all of them embedded below, followed by character photos.
