When Robert Kardashian reads O.J.'s note at the press conference, the reporters present don't know who he is and ask him to spell his surname. While assisting in O.J.'s defense raised his public profile, Robert obliquely became a household name through his daughters' reality show Keeping Up with the Kardashians (2007).
Mentions are made of the prosecution of Lyle and Erik Menendez for their parents' murder in 1994. Chris Bauer, who plays a police detective here, later appeared in Law & Order True Crime (2017) as the husband of Leslie Abramson, the Menendez brothers' defense attorney.
