Although Harry Bosch is undoubtedly , the prequel to his celebrated Prime Video series is all the better for leaving him out of its cast. Cameron Monaghan has instead been tapped to play Bosch as a 26-year-old LAPD police officer at the start of the 1990s, when racial tensions in Southern California were running high.

So pivotal is Welliver’s part in making Bosch the hugely popular and acclaimed franchise it is that he will cast a long, looming shadow over Bosch: Start of Watch, regardless of whether he features in the prequel series himself.

But it’s absolutely crucial that Welliver stays well away from the project, because if he were to appear, even in a small cameo role, it would distract from the plot of this exciting new creative venture. Moreover, the comparisons between Cameron Monaghan and the original Harry Bosch actor will already be, without the two of them also appearing side-by-side onscreen.
