A movie studio decides what gets made through a layered approval process. A script gets read, rated and passed up the chain. If it survives, executives weigh the budget against expected returns, and a small group of senior people gives the final greenlight. Most projects never make it that far.
That is the short answer. The long answer is a pipeline with more exits than entrances, and each exit has a person's name on it. Understanding the pipeline explains why familiar franchises dominate release calendars and why a good script can sit in development for years.
This piece walks the process in order: coverage, development, packaging, the greenlight meeting, and the tests a film faces after approval. The mechanics here are general industry practice, described qualitatively; studios keep the specifics of their own pipelines private, and this site does not dress up a company's marketing as independent verification.
What happens when a studio first reads a script?
Almost every script enters through coverage. A professional reader — usually a junior employee or an outside service — reads the script and writes a short report: a logline, a synopsis, and a grade, typically some version of pass, consider or recommend. The report is the product. Executives read the report, not always the script.
A 'pass' is the end of the road at that studio. A 'consider' or 'recommend' moves the script to a creative executive, who decides whether the studio should pursue it. That first filter is cheap and brutal. Studios receive far more scripts than they can ever produce, so coverage exists to kill projects quickly and cheaply.
Where does the material come from? Three main channels: agents and managers pitching clients' specs, established writers with overall deals at the studio, and rights purchases — books, articles, foreign films, life stories. Each channel has its own gatekeepers, and the agent relationship often matters as much as the page count.
What is development, and why do projects get stuck there?
Development is the phase where the studio buys or optioned the script and pays to improve it. The studio hires writers for drafts, attaches notes, and revises. An option is a rental of the rights: the studio pays a fee for the right to try to set the project up, for a set period, before the rights revert.
Development is also where projects go to stall. A studio can spend years and multiple writers on a script and still decline to produce it. The studio's money is spent, the writers were paid, and the film never exists. Industry people call the result development hell, and the label is earned: the economics reward holding options cheaply and killing projects slowly.
For the reader, the takeaway is this: development spending is not a promise. It is the studio buying the option to decide later.
How does packaging work before a greenlight?
A script alone rarely gets a greenlight. Studios greenlight packages: a script, a director, and ideally one or two bankable cast members, all lined up before the money conversation starts. Talent agencies specialize in assembling these combinations, and the pieces affect each other — a named director can attract a named actor, and both can lift the project's perceived value.
Packaging is also where the budget takes shape. The studio's production finance team models the cost: cast deals, director fee, shooting schedule, locations, visual effects, and the marketing estimate that will come later. A package that cannot clear a realistic budget-vs-return model does not reach the greenlight meeting, no matter how good the script reads.

Who actually gives the greenlight?
The greenlight is a budget-approval decision, and it sits with senior executives — typically the head of the film group and, above a threshold the company sets for itself, the CEO or board. The exact titles vary by company. The pattern does not: the bigger the number, the higher the signature.
The greenlight meeting is a finance meeting wearing creative clothes. The creative team argues the film's case. The finance side argues the model: production cost, marketing cost, and the revenue scenarios across theatrical, streaming and licensing windows. A project gets approved when the model's downside looks survivable and the upside looks worth the capital.

And for how the year's whole release calendar gets assembled around these decisions, How Studio Slate Planning Works From Board Memo to Release Date covers the layer above individual films.
Why do franchises crowd out originals in this process?
Because the greenlight model rewards predictability. A sequel or adaptation arrives with known awareness, which lowers the marketing risk and the opening-weekend uncertainty. An original script carries all of its own risk on every line of the model. When executives choose between two projects at similar budgets, the familiar one usually pencils out better on paper.
Our analysis: this is the single strongest structural force in modern slate building, and it is a direct product of the greenlight process itself — not of executives' taste. The process is designed to reduce uncertainty, and franchises are the cheapest uncertainty reduction available. Why Studios Pick Franchises Over Originals: The Economics of Familiarity follows that logic through the whole slate.
The same logic extends past the theater. A franchise character can anchor theme-park attractions and merchandise, which feeds back into what the studio can justify greenlighting. The loop is laid out in How Theme Parks Subsidize Studio Slates: The Franchise Money Loop.
What tests does a film face after the greenlight?
Approval is not the last checkpoint. During production and post-production, studios run test screenings — invited audiences watch a cut and fill out questionnaires, and the scores shape reshoots and editing decisions. A poorly testing film can trigger additional spending or, in extreme cases, a shelved release.
Then the market delivers its own tests. Theatrical demand shows up in ticket sales, which services like Fandango sit at the front of — its listings for showtimes and ticketing near individual theaters are the consumer end of the opening-weekend machine studios plan around. After the theatrical window, attention shifts to streaming, where discovery platforms such as JustWatch track where films land across Netflix, Prime Video, Disney+ and rival services, and free ad-supported platforms like Plex give older titles a second commercial life. Each window is a revenue line the greenlight model predicted — or didn't.
What the evidence does not establish: how any specific studio weights test scores against other signals, or how often a tested film changes its release plan. Studios do not publish that. Any confident claim on those points would be guesswork.
What this means for anyone following the industry
Practical steps for reading greenlight news without getting lost:
- Check who announced the number. A studio's own announcement is the company describing itself, not an independent audit of the deal.
- Separate development from production. A project 'in development' has bought an option, not a release date.
- Watch the budget tier. Big numbers mean more signatures, which means more chances to die in committee.
- Ask what the model assumed. Every greenlight is a bet on windows that have not happened yet.
The process, in one sentence: movie studios choose what gets made by filtering a flood of scripts through cheap readers, paying to develop the survivors, packaging them with talent, and letting a small group of senior executives approve the ones whose financial model holds up. Everything else — the test screenings, the release dates, the streaming windows — is the studio checking its own homework after the decision was already made.
