What is a first run?

Theatrical release windows, explained

A first run is a film's initial theatrical release — the opening window in which a new film plays exclusively in cinemas, before it reaches home entertainment, streaming, or any other platform. When people talk about a film "opening this weekend", they're talking about the start of its first run.

The term dates back to the golden age of cinema, when "first-run theatres" — the flagship houses in city centres — had exclusive rights to show new releases before they moved on to second-run and neighbourhood cinemas at lower ticket prices. The tiered system has largely gone, but the first run itself is still the commercial heart of the film industry.

Why the first run matters

The first run is where a film earns most of its theatrical box office and establishes its commercial trajectory. Opening-weekend performance shapes everything downstream: how long cinemas keep the film on screens, how it's positioned for home entertainment and streaming, and how international territories time their own releases.

For distributors, it's also the period of maximum operational intensity. A wide release can mean hundreds of cinemas, each showing the film under its own booking agreement, each reporting box office daily, each owing a negotiated share of ticket revenue back to the distributor.

How a first run works behind the scenes

Before a single ticket is sold, the distributor and each exhibitor agree terms. Across a release, that involves:

• Release and booking agreements — which cinemas show the film, from when, for how long, and on what terms.
• Film rental terms — the percentage of box office receipts owed to the distributor, which can vary by cinema, by week of release, and by territory.
• Box office reporting — daily grosses flowing back from exhibitors and box office aggregation platforms, which must be validated and reconciled.
• Settlement and invoicing — calculating the film rental actually owed under each agreement and invoicing every exhibitor.

Multiply that by several territories with different currencies, reporting standards and release dates, and the first run becomes one of the most demanding logistics exercises in entertainment.

How distributors manage it today

For a long time, most of this ran on spreadsheets and legacy systems built decades ago. That's now changing. Cinema technology company Unique X — whose software supports over 40,000 screens in more than 100 countries — has launched The Platform, a cloud-native platform that centralises booking agreements, box office data and film rental invoicing in one place. Nordisk Film Distribution was the first in the world to adopt it, running theatrical sales across Norway, Denmark, Sweden and Finland on the platform.
