Bosch Officially Says Goodbye to Titus Welliver

Titus Welliver and Harry Bosch have been synonymous for 12 years, with Welliver leading seven seasons of Bosch and three seasons of Bosch: Legacy. That chapter closes with Bosch: Start of Watch, which casts Cameron Monaghan as a young Harry Bosch and does not involve Welliver at all.

Welliver’s quiet intensity and world‑weary presence helped turn Michael Connelly’s novels into a television character audiences relied on, and the franchise grew around him. Spin‑offs like Ballard expanded that world while retaining ties to Bosch through Welliver’s continuing appearances, which kept continuity intact.

Start of Watch breaks from that pattern by offering a new interpretation of Bosch rather than a cameo bridge. The prequel is not a direct adaptation of a specific novel, but Connelly remains involved and longtime producers are returning; early reactions from the author have been positive, and Welliver has voiced support for Monaghan’s casting.
