When O.J. Simpson was on trial for the murder of his wife, he could really have used a best friend. And in Ryan Murphy's true-crime drama American Crime Story: The People v. O.J. Simpson, which recreates that trial, Simpson's getting one of the best Friends.

David Schwimmer, who played Ross on the NBC hit sitcom, is joining the cast to play Robert Kardashian, one of Simpson's confidants and attorneys, FX announced Friday.

Schwimmer joins an impressive cast that already includes Cuba Gooding Jr. as Simpson and Sarah Paulson as prosecuting attorney Marcia Clark.

The series, a new drama anthology (like Murphy's other FX show American Horror Story), will base its first season on the Jeffrey Tobin book The Run of His Life: The People v. O.J. Simpson and be told from the perspectives of the lawyers in the trial.
