Martin Sheen is set to narrate and produce Hard Evidence: O.J. Is Innocent, a docuseries that, as its name promises, will try to prove O.J. Simpson’s innocence. Airing on Investigation Discovery, O.J. Is Innocent will be the third production to catch on to the hip, en vogue trend of reexamining the brutal murders of Nicole Simpson and Ron Goldman two decades later, following in the footsteps of American Crime Story: The People v. O.J. Simpson and ESPN’s upcoming O.J.: Made in America. Sheen’s six-episode series, which claims to present new evidence and a new theory of the crime, is based largely on O.J. Is Innocent and I Can Prove It, by Texas private investigator William C. Dear. According to The Hollywood Reporter, Dear met Sheen through Sheen’s son Charlie, and that sharp clicking noise you now hear is the sound of everything making a horrible kind of sense.
