TV’s Casting Directors Betting on Unknowns
In an era dominated by social media visibility, casting directors are increasingly seeking out industry newcomers with relative digital obscurity. This strategy allows audiences to feel they are discovering new talent for themselves, creating a deeper connection to the characters on screen.
The Scale of the “Great Experiment”
HBO’s medical series The Pitt serves as a primary example of this approach. Casting directors Cathy Sandrich Gelfond and Erica Berger were tasked with filling more than 250 roles for the fictional Pittsburgh ER.
Due to the show’s immersive, 360-degree shooting style and lack of traditional marks, the team prioritized theater performers. These actors needed to be nimble and fast on their feet to move seamlessly between the background, and foreground.
The selection process is exhaustive. Berger estimates receiving between 2,000 and 5,000 headshots and résumés for a single role, eventually narrowing them down to five or seven tapes for producer review.
Prioritizing Naturalism and Chemistry
The search for authenticity often leads producers to non-professional actors. For FX’s Love Story: John F. Kennedy Jr. & Carolyn Bessette, casting directors Courtney Bright and Nicole Daniels sought a “naturally masculine” lead.
They eventually selected Paul Anthony Kelly, a Canadian model with little to no professional acting experience, just three weeks before filming began in New York City.
Beyond physical traits, a chemistry read with Sarah Pidgeon proved decisive. The decision was sealed when Kelly offered Pidgeon a ride home rather than her taking an Uber, signaling a genuine connection.
Shaping Newcomers and Improv Talent
Casting newcomers is often a collaborative process of development. Lucy Bevan, casting A Knight of the Seven Kingdoms, notes that actors are often shaped and guided by casting directors over weeks or months before they ever read for producers.
For this HBO prequel, Bevan and Emily Brockmann sought actors who could capture the comedic tone of Ira Parker’s scripts. They cast Peter Claffey as the nearly 7-foot-tall Ser Duncan “Dunk” the Tall and Dexter Ansell as the child squire, Prince Aegon “Egg” Targaryen.
Similarly, Prime Video’s Jury Duty requires actors with high-level improvisation skills. Casting director Susie Farris utilized staged focus groups where actors performed under pressure alongside unsuspecting participants.
Once cast, these performers had only one month to memorize a fake life and history within the fictional hot sauce business, Rockin’ Grandma’s.
The Balance of Veteran Presence
While newcomers are prized, casting directors also use these projects to bring veteran Broadway and West End performers to a wider audience. However, The Pitt specifically avoids actors with strong associations with recent medical shows to maintain a unique environment.

Some established names still appear in strategic roles. Mary McCormack, Dann Florek, Jeff Kober, and Rusty Schwimmer were all cast in The Pitt, providing familiar faces that audiences are happy to see again.
Future Implications for Casting
The success of these “unknown” casts could lead more studios to prioritize raw chemistry and naturalism over established fame. This shift may result in more rigorous, multi-stage audition processes that include real-world social tests.
Production teams might also continue to lean toward theater-trained actors for immersive shooting styles, as these performers are often more adept at movement without traditional marks.
