FX continues to round out the world of American Crime Story: The People vs. O.J. Simpson.

Based on Jeffrey Toobin's book, The Run of His Life: The People v. O.J. Simpson, the drama will be told through the perspective of the lawyers involved in the case and will explore the behind-the-scenes dealings on both sides of the court.

The Sopranos alum Joseph Siravo has booked the recurring role of Fred Goldman — the father of the slain Ron Goldman (played by Jake Koeppl).

The Golden Globe-winning writers on the project, Scott Alexander and Larry Karaszewski (The People vs. Larry Flynt), will exec produce with Nina Jacobson, Brad Simpson, Ryan Murphy and Brad Falchuk. Murphy is also set to direct.

Siravo, whose credits include playing John Gotti in The Wannabe, counts The Blacklist, Dirty Sexy Money and Elementary among his credits. He's repped by ATA Mangement and Hirsch Wallerstein.

He joins a cast that includes Cuba Gooding Jr. as O.J. Simpson; John Travolta as Robert Shapiro; David Schwimmer as Robert Kardashian; Courtney B. Vance as Johnnie Cochran; Sarah Paulson as Marcia Clark and Billy Magnussen as Kato Kaelin. Check out first-look photos of the cast here.
