‘Bosch’ Prequel Series Gets Green Light, and Young Harry Bosch Has Already Been Cast
Harry Bosch is back, but with a twist.
On Wednesday, MGM+ announced that it had green lit a new Bosch spinoff focused on the detective’s early years with the LAPD.
Harry Bosch: Start of Watch rolls the clock back to Los Angeles in 1996. It will follow 26-year-old Harry Bosch during his early days as a rookie cop.
“The series will explore a city on the edge, teeming with racial tension, gang violence, and a fractured LAPD,” MGM+ shared in the announcement. “Amid routine calls and growing unrest, Bosch finds himself drawn into a high-profile heist and a web of criminal corruption that will test his loyalty to the badge and shape his future as the detective who lives by the code, ‘Everybody counts or nobody counts.’”
Cameron Monaghan plays Harry Bosch in new spinoff

Cameron Monaghan will play Harry Bosch in Bosch: Start of Watch. Monaghan is known for playing Ian Gallagher on Showtime’s Shameless, twins Jerome and Jeremiah Valeska on Gotham, and Tom Fairfax in PBS’s Mercy Street. He also appears in the just-released Tron: Ares as Caius. Monaghan’s Bosch, a probationary patrol officer with the LAPD, is a “stoic, unyielding young man, intensely observant.” He already “possesses all the qualities that will come to mark his legendary career: he’s smart, relentless, determined, fiercely protective of the victims of crime.”
Omari Hardwick (Power, Army of the Dead) will play veteran officer Eli Bridges in the new show. Training officer Bridges is a “seasoned, salty” Vietnam vet who guides the young Harry “through the mean streets of Los Angeles and the complicated world of the LAPD. Bridges is fighting a war on the streets and looking for soldiers, and they don’t come any brighter than Hieronymus Bosch.”
‘Bosch: Start of Watch’ will film in Los Angeles
Like Bosch, Bosch: Legacy, and Ballard, Bosch: Start of Watch will film on location in Los Angeles starting in 2026.
“It’s a terrific privilege to be able to explore both the origins of this iconic character and the Los Angeles that formed him in the early 1990s,” said series co-creator and executive producer Tom Bernardo.
“I’m deeply grateful to Michael Wright and the team at MGM+ for championing this next chapter in Bosch’s journey with such remarkable care and integrity,” said Michael Connelly, author of the best-selling series of Bosch novels. “Being able to see how Harry Bosch became the man we have loved for 10 seasons is a gift to me and his many fans. I can’t wait to dig in with Cameron and the writers to explore this uncharted character territory.”
