O.J. Simpson documentaries to air on A&E and LMN

The 20th anniversary of the verdict in the Trial of the Century will bring two new documentaries about O.J. Simpson.

LMN will debut The Secret Tapes of the O.J. Case: The Untold Story on Sept. 30 at 8 p.m., while sister network A&E will unveil O.J. Speaks: The Hidden Tapes the following night at 9 p.m. ET. Both two-hour programs — which are executive produced by American Tragedy author Lawrence Schiller, who was close to Simpson lawyer Robert Kardashian — feature never-before-heard recordings and interviews.

The Secret Tapes of the O.J. Case: The Untold Story promises new insight into how Simpson was acquitted of the murders of his ex-wife Nicole Brown Simpson and Ron Goldman on Oct. 3, 1995. According to the network, the documentary “exposes disturbing realities about O.J.’s thoughts, feelings and behavior before, during and after the trial,” and presents an audio recording made by Simpson before the infamous slow-speed freeway chase, as well as interviews with people on both sides of the case, including Kardashian and his ex-wfie Kris Kardashian Jenner.

O.J. Speaks: The Hidden Tapes takes you behind the scenes of O.J.’s civil trial, which in 1997 found him liable for the deaths of Nicole Brown Simpson and Goldman. That special boasts access to the plaintiff’s deposition tapes, whch have been held in storage for almost two decades, as well interviews with family members such as Ron Goldman’s father, Fred, and lawyers from the civil trial. Both docs are also exec-produced by Stephen Auerbach and Chuck Braverman, who worked with Fred Goldman to acquire the deposition tapes.

Among the other O.J. projects in the works is the FX miniseries American Crime Story, with season 1 focusing on the Simpson criminal trial. It is slated to air next year.

Simpson is currently serving a 33-year prison sentence for armed robbery and kidnapping.
