Omari Hardwick co-stars as Eli Bridges, Bosch’s veteran training officer in the show. Additional cast members include JD Pardo, Ariana Guerra, William Fichtner, and Azita Ghanizada. Tom Bernardo and Brian Anthony co-created the series, with Bernardo serving as showrunner.
Michael Connelly, the bestselling author behind the Bosch book series, also executive produces the project. The show is scheduled to air on MGM+ in 2026, though an exact premiere date remains unannounced.
