So, you’re scrolling through Prime Video and you see this show called On Call. It looks gritty. It looks like a high-speed chase through the streets of Long Beach. And then you see the name Tim Walsh.
If you're like most people, you might be scratching your head. Is this the guy from KPMG? The toy inventor? Or the guy who wrote for Chicago P.D.? Honestly, the "Tim Walsh" world is pretty crowded, but the one people are buzzing about right now is the creative force who teamed up with Elliot Wolf to reinvent the police procedural.
Who exactly is the Tim Walsh behind On Call?
Tim Walsh isn't your typical Hollywood insider. He’s a Chicago native who took a pretty winding path to get to the showrunner's chair. We're talking about a guy who openly discusses making "poor decisions" in his youth—the kind that could have landed him in a very different kind of institution. Instead, he grabbed a second chance by the horns, earned his GED, and worked as a security guard while teaching himself how to write scripts.
That grit shows up in his work. You've probably seen his name on the credits of Chicago P.D., where he spent four seasons. He also cut his teeth on Hightown, Shooter, and Treadstone. But On Call is his baby. It's the first scripted streaming series from Wolf Entertainment (yes, the Dick Wolf empire), and Walsh is the one steering the ship as executive producer and showrunner.
The technical nightmare that actually worked
When On Call premiered in early 2025, people weren't just talking about the plot. They were talking about how it looked.

Walsh and his team decided to ditch the traditional "cinematic" look for something much more visceral. They used a mix of:
- Hand-held cameras
- Real bodycam footage
- Dash-cam angles
- Cellphone video
Basically, it's designed to make you feel like you're trapped in the back of the cruiser. Walsh has mentioned in interviews that this was a total headache to film. You can’t "stage" a scene the normal way when someone is wearing a bodycam with a massive wide-angle lens. If a crew member is standing three feet away, they’re in the shot. It required the actors—like Troian Bellisario and Brandon Larracuente—to essentially become their own camera operators.
Why the half-hour format?
Most cop shows are an hour long. They start with a body and end with handcuffs. Walsh took a different route. On Call episodes are 30 minutes.
It’s fast. It’s serialized. It feels more like Southland or The Shield than it does Law & Order. Walsh's logic? Modern viewers don't always have an hour to commit to a slow-burn procedural. They want the adrenaline hit, and they want it now. By keeping the runtime tight, the show avoids the "filler" scenes where characters sit around drinking lukewarm coffee and explaining the plot to the audience.

It’s not just about the "blue"
There’s a lot of debate right now about how police are portrayed on screen. Walsh seems acutely aware of this. He’s gone on record saying the show is about "human beings first who happen to be police officers."
The series follows a veteran, Traci Harmon (Bellisario), and a rookie, Alex Diaz (Larracuente). Walsh uses that dynamic to explore the gray areas. It’s not a "black and white" morality play. He specifically pushed for the "criminal element" in the show to be three-dimensional. You aren't just watching "bad guys" get caught; you're seeing people in crisis.
The "Other" Tim Walshes (Don’t get them confused)
If you're searching for "Tim Walsh on call" and finding weirdly specific business advice, you’ve hit a different guy.
- The KPMG CEO: Timothy J. Walsh is a heavy hitter in the world of audit and tax. He’s the Chair and CEO of KPMG U.S. If your "on call" needs involve SEC filings or multi-billion dollar mergers, he's your man.
- The Toy Expert: There is a Tim Walsh who is a world-renowned toy and game historian. He wrote Timeless Toys and won "Game Designer of the Year" in 2025. He's amazing, but he probably won't help you write a gritty TV pilot.
- The Risk Advisor: Another Tim Walsh leads the Design & Construction practice at Unison Risk Advisors.
The On Call Tim Walsh is the storyteller. He's the one who spends his time figuring out how to make you care about a traffic stop in Long Beach.

What you can learn from Walsh's career
Honestly, Walsh’s career path is a masterclass in persistence. He didn't move to LA until 2000 and didn't land a staff writing job until 2011. That's over a decade of grinding.
Practical Takeaways from the Walsh Playbook:
- Value the Life Lived: Walsh has said he doesn't care much about a writer's resume; he cares about the obstacles they’ve overcome. If you're trying to break into a creative field, your "real world" struggles are often your best source material.
- Ditch the Ego: When working with Elliot Wolf, Walsh emphasized being "egoless." In any partnership, you have to accept that there are ten different ways to tell a story. Yours might not be the best one.
- Stay on the Move: Just like the show, your projects should avoid stopping for too long. Momentum is everything in storytelling.
If you haven't checked out the show yet, it's worth a watch just to see how Walsh handles the technical constraints of the "POV" style. It's a bold move for a brand as established as Wolf Entertainment, and it's largely thanks to Walsh's willingness to experiment.
Keep an eye on the credits. Whether he's showrunning a new season or popping up as a guest speaker at the Marketing Society, this Tim Walsh is currently one of the most interesting voices in the transition from traditional TV to the streaming-first world.
