Full account
MGM+ has released first-look images of Cameron Monaghan and Omari Hardwick in Bosch: Start of Watch, a prequel centred on the early career of detective Harry Bosch. The eight-episode series is due to premiere on 10 January 2027 with two episodes, then continue weekly until its finale on 21 February.
Monaghan plays Bosch at 26, newly joined to the Los Angeles Police Department in 1992. Hardwick plays Eli Bridges, a veteran officer who becomes his mentor. The other named regulars include Ariana Guerra as fellow rookie Rosa and JD Pardo as Cory, Bosch’s foster brother. The ensemble also includes Kathleen Wilhoite, William Fichtner, Rafi Gavron, Raphael Sbarge, Azita Ghanizada, Kenneth Miller, Seamus Dever, Ryan McPartlin, Marco Rodriguez and Shelli Boone.
The series places Bosch’s first police work amid racial tension, gang violence and turmoil within the LAPD. Its story follows routine calls and rising unrest as Bosch becomes involved in a prominent heist and a corruption case, putting his loyalty to the badge under pressure. The character was created by Michael Connelly, whose novels also inspired the earlier television adaptations; this prequel’s plot, however, is described by one report as an original story rather than an adaptation of a specific book.
The new casting marks a change from the earlier shows, in which Titus Welliver played Bosch. The original Bosch ran for seven seasons, followed by the three-season sequel Bosch: Legacy, which depicted the retired detective working privately. Start of Watch is co-created by Tom Bernardo and Brian Anthony, with Bernardo as showrunner; both reports note his connection to the previous series. It is produced by Fabel Entertainment, with Connelly among its executive producers.
Where outlets differ
From the full account, which is AI-written from the sources:
One report explicitly says Start of Watch is not based on any of Connelly’s novels. The other describes the series as based on his bestselling book series, while also presenting a new origin-story plot; it does not identify a particular novel as its source.
The first report foregrounds the recasting and the history of the two earlier series, and gives Bosch’s Persian Gulf War service as background. The second focuses more on the 1992 setting, the heist and corruption storyline, and names a larger supporting cast and production team.
The first report says the series will debut on MGM+ without specifying territories. The second lists the United States, United Kingdom, Belgium, Ireland, Italy, Germany, the Netherlands, Spain and Latin America as its release markets.
Explained simply
Harry Bosch is a fictional Los Angeles police officer at the centre of the series Bosch and its follow-up, Bosch: Legacy. The earlier shows starred Titus Welliver as Bosch later in his career; the new prequel goes back to his first years in the Los Angeles Police Department.
The story is set as the city faces racial tension and violence, and presents Bosch as a Gulf War veteran beginning police work. Cameron Monaghan plays the younger Bosch, with Omari Hardwick as his mentor Eli Bridges, Ariana Guerra as fellow rookie Rosa and J.D. Pardo as his foster brother Cory.
The character comes from crime novels by Michael Connelly, but this prequel is an original television story rather than an adaptation of one of his books. Tom Bernardo, who worked on the earlier series, is its showrunner.
