Originally shot in 2006, the conversation between Mr. Simpson and the publishing magnate Judith Regan was intended then to promote the ReganBooks release of “If I Did It,” described as a “hypothetical” explanation of how the N.F.L. Hall of Famer might have murdered his ex-wife Nicole Brown and her friend Ron Goldman — a crime for which he was acquitted in 1995.
Hosted by Soledad O’Brien, “The Lost Confession” alternated clips from the interview with new commentary from a panel that included Ms. Regan, Christopher Darden (the lawyer who helped prosecute the original case), Jim Clemente (a retired F.B.I. profiler), Rita Smith (a spokeswoman for the National Coalition Against Domestic Violence), and Eve Shakti Chen (a friend of Ms. Brown’s).
