Who Controls the Screenplay Controls the Room

By Stephen Cyrus Sepher

The first thing David Boxerbaum says isn’t a flex in the Conversation Podcast. It’s a thesis. You’re nothing without the screenplay. In a town that worships packaging, algorithms, and celebrity rosters, that line lands like a reminder from a different era. The page is still the power source. Everything else is leverage built around it.

“Who controls the screenplay controls everything,” he says.

We talk endlessly about agents, but rarely about what makes one actually take a chance on something. Behind every script that breaks through, there’s a decision, a private calculus that no one writes about. It’s not just whether a screenplay is good. It’s whether it feels alive. Agents ask themselves questions in quiet moments: Does this voice cut through the noise? Does the market need this story or is it just another echo? Can I walk this into a room and feel proud to be behind it?

Because agents don’t just sell. They curate. They decide which writers are worth betting their own reputation on, which stories have the gravity to pull others toward them. In 2025, control is no longer about who owns the rights. It’s about who owns the momentum. The agent’s job isn’t to chase, it’s to generate pull. Not through ego, but through intuition, taste, and timing.

The Apprenticeship Behind the Curtain

David’s story begins the way so many Hollywood stories do…at the bottom of the food chain. The mailroom. From there he rose to assistant, then agent, then partner. Between walking dogs, organizing script libraries, and fetching lunches, he had a front-row seat to Armageddon, Con Air, and Enemy of the State. He was learning in real time how the machine runs.

The mailroom has become mythology for a reason. It’s where observation replaces entitlement. Michael Ovitz started there. So did David Geffen. So did Ari Emanuel. For decades it has been Hollywood’s unofficial bootcamp, a place that tests ambition and teaches rhythm.

But more than anything, it teaches temperature. You learn the climate of the business. Who’s hot, who’s fading, who’s untouchable. You learn to read the emotional air before you walk into a room. You learn which executives mean what they say and which ones are rehearsing their own politics. You begin to understand that survival here isn’t just about aggression, it’s about awareness.

In an industry that runs on whispers and timing, emotional intelligence is currency. One wrong move can freeze a relationship for years. The people who last don’t just have drive; they have sensitivity. They know when to press, when to wait, and when silence says more than another follow-up email ever could.

The mailroom isn’t just an initiation. It’s a kind of X-ray. It shows you what moves through the arteries of Hollywood, what clogs, what flows, what dies. You start recognizing patterns. You start anticipating decisions before they’re made. Pattern recognition becomes survival.

The Reality of Representation

Every writer sits somewhere on the same axis of access.

There are writers with representation who are getting into rooms. They’re the ones whose reps are actively pushing, leveraging relationships, and keeping their clients’ names in circulation. These are the writers who create work that feels immediate, relevant, and sellable right now.

Then there are writers who have representation but can’t get into rooms. They’re talented, maybe even brilliant, but dormant. Their agent believes in them enough to keep them signed but not enough to prioritize them. These are the invisible clients. The ones waiting for a call that may not come. The truth is, the industry forgets fast. The only way to wake it up is with new work. Write something undeniable. Make something yourself. Give your rep a reason to re-engage.

And then there are the writers with no representation at all. The outsiders. The ones building without permission. Once upon a time, the system ignored them completely. Now, it can’t afford to. Contests, fellowships, short films, YouTube pilots, Substack serials, podcasts, each one can function as proof of concept. The walls still exist, but they’re thinner. Sometimes the side door is the only way in.

What separates these three groups isn’t luck or even talent. It’s velocity. The industry rewards movement. It’s drawn to the energy of people who keep creating, regardless of the noise.

The Temperature of Now

When you listen to someone like David Boxerbaum, what emerges isn’t just a portrait of one agent’s career. It’s a snapshot of how the business really feels right now. Cautious. Sensitive. Simultaneously shrinking and expanding. Everyone walking on eggshells, yet still trying to claim space. The power dynamics have softened but not disappeared. The people who thrive are the ones who know how to move through the tension with grace.

The work still matters. The relationships still matter. The timing matters more than ever. But what matters most, the thing no algorithm or agency can replicate is the ability to stay human in a business that often forgets to be.
