August 27, 2025
Following her acquittal, Karen Read partnered with LBI Entertainment to adapt her story for the screen, adding a personal dimension to the dramatization.
A new limited series is in development, produced by Warner Bros. Television, that explores the controversial case of Karen Read, a Boston woman accused of murdering her boyfriend, police officer John O’Keefe, a case that drew national attention.
The series is based on the popular podcast 'Karen,' produced by Law & Crime and Wondery, which was acquired by Brownstone Productions, and will delve into themes like society's obsession with true crime, conspiracy theories, and institutional trust.
Justin Noble, known for 'The Sex Lives of College Girls,' will serve as the showrunner and writer, bringing his experience in popular TV comedy to this serious true crime story.
Elizabeth Banks is set to star as Karen Read and will also serve as an executive producer through her Brownstone Productions, marking a significant acting role in a courtroom drama based on a real case.
Karen Read was acquitted in June 2022 of murder and manslaughter charges related to her boyfriend's death after a previous mistrial, with the case continuing to generate media interest.
The plot centers on the investigation into Officer O’Keefe’s death, with Read accused of first-degree murder but ultimately acquitted of second-degree murder and manslaughter.
Read and her defense attorney, Alan Jackson, are developing a separate scripted adaptation of her case with LBI Entertainment, the studio behind 'Killers of the Flower Moon,' as part of a broader effort to dramatize the story.
The case has captivated the public and media, sparking debates over her guilt and allegations of a law enforcement cover-up, and inspiring news specials and a Netflix documentary.
Elizabeth Banks’s involvement in the series continues her recent collaboration with Prime Video, following their success with 'The Better Sister,' and she remains a prominent figure in this project.
With David E. Kelley’s recent Emmy-nominated courtroom drama 'Presumed Innocent,' the project benefits from his proven expertise in legal storytelling.
The series aims to explore the complex circumstances surrounding Karen Read’s legal case, focusing on her trial and the events leading up to her charges.
