ENTERTAINMENT WEEKLY: You’ve played this character for 10 seasons, about 10 years, nearly 100 episodes.

How does it feel to be wrapping up the main Bosch saga as we know it?

TITUS WELLIVER:Terrible, it feels terrible.

I love Harry Bosch and I miss him.

But I’m extremely proud of what we’ve accomplished in 10 years.

It’s hard to say goodbye to that, but never say never.

I was really taken aback.

I don’t think any of us anticipated that at all.

So my immediate response was kind of shock, and then deep disappointment, a kind of disbelief.

But some of it, as Harry would say, it’s above my pay grade.

It was not due to any kind of salary disputes or anything like that.

A command decision was made, and that’s the way it goes.

I think it’ll be a show that’ll run and rerun and find new audiences over the years.

What’s it like to see that kind of support?

I find it deeply touching and moving.

The fans have always, from the beginning, been really, really supportive.

And I was not a social media guy until I didBosch.

And I really enjoyed interacting with the fans, and still continue to do so.

Can you tell us anything about where a season 4 might have gone?

Well, it was funny.

Tim Marcia, were there.

And I said, “Because I feel like a cop again.”

And I said, “Well, come on, Mike.

In the books, he volunteers for the San Fernando Police Department as a cold-case homicide detective.”

And Tim said he definitely could.

And so we talked about that for a little bit.

You’ve expressed interest in doing some kind ofBoschcontinuation, be it more episodes or something feature-length.

What’s appealing to you about that?

It’s the character and it’s the experience.

And there are a lot more stories to be told.

I mean, that’s the thing.

So there’s so many different avenues.

My brain sometimes is a very, very busy place, and I get inspired.

Or is this just the season as it was made?

That’s just what happened.

I mean, there’s no ultimate closure.

We always left things a little bit up in the air [at the end of a season].

It was just what’s done was done.

So it ends in the way that most seasons ofBoschdo.

There’s not definitive finality to it, but there’s no cliffhanger.

Is there anything you didn’t get to do that you would’ve liked for a final season?

Well, I’d have brought everybody back.

If I’d known that, I would’ve said, “You know what?

What do you imagine Harry’s headspace is like after going through all that?

I think he comes as close to the edge as we’ve ever seen him before.

And it’s not that he’s unaware of that darkness and the fact that it can penetrate you.

I think he heals himself, in his own way.

And I think that, more than anything, would be something that we would see him do.

But the only way that he does that is by continuing the process.

So it makes perfect sense that you would have Harry just go right back to work.

He’d be looking for the next thing because that’s, oddly, his safe place.

It’s his work that carries him through, even through the darkness.

Patrick Wymore/Prime

We talked a little bit about Ballard coming on the scene.

We hit it off right away.

We have a million friends in common, but we hit it off right away.

I know it’s in very capable hands with her.

Maggie really got the character.

That’s integral to the success of it.

Can you tell us anything about what’s in store there?

I don’t want to spoil anything.

Here’s what I will say: I don’t think it’s anything that’s earth-shattering.

I think it is just sort of some of the connective tissue between the universes.

But I love working with Maggie.

But that’s the beauty of it.

That’s what you hope for, and that was the experience of doingBoschall those years.

It was really, really fun.

You recentlysigned a first-look deal with Amazon, so you’ll be continuing that creative partnership.

What sorts of projects are you looking to do next?

AndBoschis a tough act to follow.

It’s in its infancy.

We’re just starting to really have real-time conversations with material and where we want to go with it.

There’ll definitely be some great stuff coming down the pike.

And Michael Connelly and I and Henrik Bastin and Tom Bernardo, we continue to work together.

We’ve got some ideas, so stand by.
