Screenwriter

Screenwriter

noun | Screenwriting & Development

The person who writes the screenplay -- the formatted written document from which a film is made. The screenwriter translates a story concept into scene headings, action descriptions, and dialogue using standard industry format. The screenwriter may originate the story from their own ideas, adapt existing source material (a novel, a true event, an article), or rewrite work started by another writer. In studio productions, a single script may pass through multiple screenwriters before production.

The Explanation: How & Why

The screenwriter occupies a paradoxical position in the film industry: their work is the origin of the project, yet they typically lose creative control of it once it is sold or put into development. A novelist controls every word of the published book; a screenwriter hands the script to a director, producer, and studio who may then rewrite it, hire other writers to revise it, or change it substantially during production. This is not a flaw in the system -- it reflects the collaborative nature of filmmaking -- but it is a structural reality that shapes every working screenwriter's career.

In the American studio system, the Writers Guild of America (WGA) governs minimum payments, credit arbitration, and residuals for WGA-covered productions. Writing credit on a studio film is determined by a formal arbitration process: the WGA reads all drafts of the screenplay and assigns credit -- "Written by," "Screenplay by," or "Story by" -- based on the contribution of each writer to the final film. A writer who originates the story may receive story credit while another writer who substantially rewrote the script receives screenplay credit.

On independent productions, the screenwriter and director are often the same person. The writer-director model gives the writer full creative continuity from page to screen -- but also requires the writer to subordinate their writerly instincts to the practical realities of production.

Historical Context & Origin

The first film scripts were not written by specialised writers. Directors and producers wrote the brief scenario cards that guided early productions. As narrative complexity grew in the 1910s, studios began hiring dedicated title card writers and then scenario writers -- often recruited from journalism, theatre, and novels. The transition to sound in 1927 dramatically increased the demand for dialogue writers, and studios began importing playwrights and novelists from New York and London in large numbers.

The Screen Writers Guild (later the WGA) was founded in 1933 to protect writers' rights in contract negotiations with studios. The first major WGA strike (1960) established residual payments for films sold to television -- the beginning of the residual system that now governs payments for streaming.

How It's Used in Practice

Scenario 1 -- Development (Writer): A screenwriter pitches an original spec concept to three production companies. Two pass; one offers to option the script for $15,000 against a purchase price of $150,000. The writer, working with an entertainment lawyer, negotiates to retain the right to write the first rewrite if the project is greenlit, protecting their continued involvement.

Scenario 2 -- Production (Director / Writer): A writer-director arrives on set for day one of principal photography with the production draft locked. During rehearsal of the opening scene, an actor finds a line that does not feel natural in the character's voice. The director-writer revises the line on the spot, drawing on both the script's underlying intent and the actor's instinct to find a better version.

Scenario 3 -- Post-Production (Producer / Writer): During the edit, a structural problem emerges: the second act loses momentum because a key scene was cut for location logistics during production. The producer brings the original screenwriter back to write a replacement scene that can be shot as a one-day pickup, restoring the narrative beat the production cut eliminated.

Usage Examples in Sentences

"The screenplay is credited to two writers who worked on it in sequence, though the final shooting draft reflects elements of both drafts."

"Her first produced screenplay won a WGA Award; she followed it with two unproduced specs before selling her third."

"The director rewrote several scenes during production, but the film's overall structure remained true to the original screenwriter's draft."

"In WGA arbitration, the credited writer receives residuals from every subsequent use of the film -- broadcast, streaming, and home video."

Common Confusions & Misuse

Screenwriter vs. Author: A novelist retains copyright over their finished work. A screenwriter who writes under a work-for-hire agreement (the default for commissioned studio work) does not own the copyright to the finished screenplay -- it belongs to the commissioning party. An original spec screenplay written outside any agreement belongs to the screenwriter until it is sold. Understanding the work-for-hire distinction is critical before signing any writing agreement.

Screenwriter vs. Story Writer: In WGA credit determinations, "Written by" indicates one writer contributed both story and screenplay. "Story by" and "Screenplay by" as separate credits indicate the story originated with one writer and the screenplay was substantially rewritten by another. These distinctions affect residuals and credit visibility.
