Production has officially concluded on Bosch: Start of Watch, the highly anticipated prequel series to the long-running Amazon Prime Video hit Bosch. According to a social media update from cast member Ryan McPartlin, the production team has wrapped filming for the first season, which is slated to debut on MGM+ in 2026. The series explores the origins of Harry Bosch, focusing on his early years as a rookie patrol officer in 1991 Los Angeles.
What is the premise of Bosch: Start of Watch?
The series serves as an origin story for the iconic detective Harry Bosch, portrayed by Cameron Monaghan. Based on the universe created by bestselling author Michael Connelly, the narrative is set in 1991, a period characterized by significant social unrest and systemic challenges in Los Angeles. The plot centers on a young, 26-year-old Bosch as he navigates his entry into the LAPD, eventually becoming embroiled in a complex web of criminal corruption and high-stakes heists. The show aims to establish the moral framework that defines the character throughout his later career, specifically his guiding mantra: “Everybody counts or nobody counts.”
Who is in the cast and production team?
The series features an ensemble cast led by Cameron Monaghan. Ryan McPartlin joins the production as Detective Mike Garner, a role for which the actor conducted research with the LAPD Southeastern Division. Omari Hardwick takes on the role of Eli Bridges, who serves as Bosch’s veteran training officer. According to official studio announcements, the supporting cast includes JD Pardo, Ariana Guerra, William Fichtner, and Azita Ghanizada. Behind the camera, the show is co-created by Tom Bernardo and Brian Anthony, with Bernardo serving as showrunner. Michael Connelly serves as an executive producer, ensuring the series remains consistent with the tone and themes of his established literary franchise.
Why does this prequel matter for the Bosch franchise?
Bosch: Start of Watch represents a strategic expansion of the Bosch IP, moving the narrative from the established Amazon Prime Video ecosystem to the MGM+ streaming service. This shift follows the success of the original series and its spinoff, Bosch: Legacy. While Bosch: Legacy continued the story of an older, independent Harry Bosch, this prequel provides a tonal contrast by grounding the viewer in the early 90s, offering a “boots-on-the-ground” perspective of police work during a period of intense civic volatility. By centering on the rookie experience, the series provides a grounded counterpoint to the more seasoned, investigative-heavy arcs seen in later iterations of the franchise.
