The entertainment company Hollywood Ventures Group, founded by executive Glenn Gainor and producer Sandy Climan, has acquired screen rights to an upcoming memoir by Dr. Erroll Southers. The project is described as an optioned work intended for development into either a feature film or a television series, with the company planning to translate the book’s firsthand accounts of counterterrorism and public safety into dramatized storytelling. The memoir, titled Inside the Castle Walls, reportedly delivers an insider’s perspective that could lend itself to both procedural and character-driven approaches on screen, combining policy detail with personal struggle.
About Dr. Erroll Southers
Dr. Erroll Southers brings decades of experience across federal, state and local security posts. He has served as President of the Los Angeles Board of Police Commissioners and currently oversees public safety at the University of Southern California as Associate Senior Vice President of Safety and Risk Assurance. His earlier career includes time as an FBI Special Agent and a member of a SWAT team, leadership as Deputy Director of the California Office of Homeland Security under Governor Arnold Schwarzenegger (who contributed a foreword to the memoir), and a tenure as Chief of Homeland Security and Intelligence for the Los Angeles World Airports Police Department. He was also President Barack Obama’s first nominee for Assistant Secretary of the Transportation Security Administration, a nomination he ultimately withdrew.
The memoir and the author’s public voice
Inside the Castle Walls is presented as a chronicle of decades spent at the intersection of counterterrorism, law enforcement and policy-making. Southers is already the author of Homegrown Violent Extremism and has regularly contributed analysis to national outlets such as USA Today and the Los Angeles Times. His public profile includes television appearances on programs like History’s America’s Book of Secrets: The FBI, Bravo’s Spy Games and CNN’s The Nineties, which established him as a commentator who blends operational experience with accessible explanation of complex security topics.
The adaptation plan and production leadership
Hollywood Ventures Group intends to develop the memoir for both film and television possibilities, leveraging the founders’ industry backgrounds. Glenn Gainor, who previously led operations at Amazon MGM Studios, and veteran producer Sandy Climan will shepherd initial development activity. Gainor praised Southers’ combination of lived experience and commitment to reform, noting that few people grasp the nuances of global security and the human side of public service with such depth. He described the book as a narrative that mixes systemic critique with personal perseverance and suggested the material could translate into compelling, authentic drama.
What the story offers artists and audiences
Adaptation discussions reportedly focus on themes that include institutional change, resilience and the moral complexity of security work. The book’s emphasis on the human element of public safety—how individuals and communities respond under pressure—creates opportunities for character arcs that probe leadership, trust and redemption. Producers could choose a procedural format that highlights specific incidents and operational detail, or a limited series that explores a lifetime of policy battles and personal sacrifice. The presence of a foreword by a high-profile political figure adds a layer of public interest and contextual authority to the narrative.
Next steps and representation
Neither a production schedule nor casting details have been released; studio representatives say further announcements about timelines, casting and distribution will come later. Dr. Erroll Southers characterized the partnership with Hollywood Ventures Group as an opportunity to broaden the memoir’s reach and said he hopes the chapters of his life and career will inspire others to tackle obstacles in pursuit of systemic improvement. He framed the book as more than memoir—an invitation to conversation about public safety and civic duty. Southers is represented by Steven Adams of Alta Global Media, who will handle media and industry negotiations as the adaptation moves forward.
