Landing a role on a major network procedural requires a precise mix of timing, chemistry, and rigorous audition loops. When casting directors built the ensemble for a major broadcast hit, they looked for actors who could anchor high-stakes tactical scenes while maintaining grounded personal dynamics.
The process behind populating the screen with special agents, informants, and antagonists relied on established Hollywood casting infrastructure. Susan Bluestein and Jason Kennedy, the primary casting directors behind the series, managed a multi-tiered pipeline that evaluated everything from traditional theatrical training to physical stunt readiness. Understanding how major action-dramas source their talent reveals the mechanics behind modern television production.
The Architecture of Procedural Casting
Casting a long-running investigative drama starts well before cameras roll on a pilot episode. Producers and casting directors collaborate to establish character profiles that balance procedural archetypes with distinct personality quirks. For a series set in Southern California's tactical underworld, talent scouts needed performers who could pivot instantly from heavy exposition to firearms handling and hand-to-hand combat choreography.
Principal roles typically move through standard industry channels:
- The Breakdown: Producers issue detailed character breakdowns to franchised talent agencies detailing age ranges, physical descriptors, and required emotional range.
- Initial Auditions: Actors submit self-tapes or read live for casting directors, focusing heavily on line delivery and immediate screen presence.
- Producer and Network Sessions: Shortlisted performers test for the show's creator, executive producers, and network executives, where chemistry reads determine how well opposing actors play off one another.
Chemistry and the Core Ensemble
The longevity of an ensemble procedural rests entirely on interpersonal dynamics. During auditions for lead characters, casting directors run multiple combinations of actors to test chemistry. When Chris O'Donnell and LL Cool J auditioned or chemistry-tested for their respective roles, producers prioritized the friction and mutual respect between veteran field operatives.
Supporting characters undergo a similar crucible. The addition of tech specialists and field analysts requires performers who can make technical jargon sound urgent rather than dry. Talent scouts look for actors with theatrical backgrounds who possess strong vocal projection and natural comedic timing to balance the show's darker elements.
Sourcing Background Talent and Stand-Ins
While principal actors secure parts through theatrical agents, the massive machinery of a show like this requires thousands of background actors, stand-ins, and photo doubles. In major production hubs like Los Angeles, background casting agencies manage this influx.
Extras are chosen based on wardrobe fit, typecasting requirements for specific scenes—such as military personnel, law enforcement officers, or civilian bystanders—and union status. Stand-ins, who mirror the height and skin tone of principal actors to help lighting crews set shots, must understand technical camera blocks and remain patient during long setups. Productions frequently source these workers through dedicated casting platforms and background databases.
Common Misconceptions About Television Casting
A frequent myth among aspiring performers is that major network shows hold open cattle calls for principal roles. In reality, unions like SAG-AFTRA and the sheer volume of submissions make open casting calls rare for scripted television. Almost all professional television acting roles require representation by a franchised talent agent or manager who has direct access to casting breakdowns.
Another misunderstanding involves the audition timeline. Performers often assume casting decisions happen overnight, but a recurring or guest-starring role on a major network procedural can involve weeks of network approvals, wardrobe tests, and scheduling alignment before a contract is finalized.
Frequently Asked Questions

What qualifications do background actors need?

Who were the main casting directors for the series?
Susan Bluestein and Jason Kennedy served as the primary casting directors for the production, guiding the talent search across its multi-season run.
Why is chemistry testing crucial for action dramas?
Action dramas rely heavily on partner dynamics and team trust. Producers must see how actors interact physically and verbally under simulated high-pressure scenarios before casting them together.
