Bosch: Start of Watch Prequel Sets MGM+ Premiere for Jan. 10, 2027
Cameron Monaghan plays a young Harry Bosch in the prequel series, which is not adapted from a specific Michael Connelly novel.
MGM+ has set Jan. 10, 2027 as the premiere date for Bosch: Start of Watch, a prequel series in the Bosch franchise, according to movieweb.com. Cameron Monaghan will play a young Harry Bosch.
The prequel is not based on a specific novel by Michael Connelly, the author who created the detective. That separates it from the earlier Bosch series, which was adapted from his books.
Bosch ran for seven seasons on Prime Video from 2015 to 2021. A sequel series, Bosch: Legacy, followed for three seasons and followed Harry Bosch as a private investigator.
A franchise that keeps expanding
The franchise has also branched out through Ballard, a spin-off centered on LAPD Detective Renée Ballard, played by Maggie Q. The character first appeared in Bosch: Legacy Season 3.
Connelly has published more than 20 novels centered on Harry Bosch, along with novellas and spin-offs. Titus Welliver played the lead in the two previous Bosch series; Monaghan takes over the role for the prequel’s younger version of the character.
