Netflix's potential acquisition of Warner Bros. has quickly gone from being a simple corporate move to one of the most serious debates about the future of cinema. Beyond the multi-million dollar figures involved, what has truly set off alarm bells is a very specific number: 17 days , the period the platform reportedly wants to establish as the exclusive theatrical window for the studio's films before releasing them on streaming.
Various reports from outlets such as Deadline and ScreenRant suggest that, if the deal goes through, Warner Bros. blockbusters would no longer enjoy their usual 45-day (or even longer) run in theaters. This reduction, which on paper might seem like just a scheduling adjustment, is perceived within the industry as a direct blow to the heart of the cinema business, including in Spain and the rest of Europe , where traditional exhibition remains crucial for the viability of thousands of theaters.
From 45 days to 17: why this change turns everything upside down
According to leaks, Netflix's plan would involve Warner Bros. films enjoying only 17 days of theatrical exclusivity before becoming available on the subscription service. This means just over two weeks from their theatrical release to their arrival on the platform's catalog, a gap that currently typically occurs between 45 and 70 days, depending on the title and the market.
For major theater chains, such as AMC in the United States, this minimum threshold is considered essential for a release to recoup investments in marketing, theater operations, and distribution agreements, as happened with box office hits like Moana 2. Reducing it to 17 would mean, in practice, that a large part of the audience would assume it's worth waiting a couple of weeks to see the film at home, especially if they already have an active subscription.
The main question is whether those 17 days represent the maximum theatrical run or just the exclusivity window. Some analysts suggest the latter is more likely: that after that period, the film will become available on Netflix but could continue to be shown in theaters for a while. Even so, the impact on box office revenue could be significant, since the peak attendance is usually concentrated in the first three or four weeks.
The fear among European and Spanish exhibitors is that a pattern similar to the one Netflix already uses for its own titles will be transferred to cinemas: very limited releases in a few theaters , for a minimal time, to meet award requirements like the Oscars, while the real focus is on the global launch on the platform. With Warner Bros. under its control, this model would no longer only affect in-house productions but would also impact major franchises that currently drive a significant portion of the box office.
A delicate context: weakened box office sales and risk of collapse
The debate over the 17-day window comes at a particularly fragile time for cinemas. Global figures show that, from 2019 to 2025, annual box office revenue has fallen by around 20% , from approximately $11.264 billion to around $8.870 billion. The recovery from the pandemic has been partial, and in many European markets, cinemas are still operating below pre-pandemic levels.
In this scenario, a potentially fatal blow is perceived as a consequence of further shortening the exclusivity window. Several studio executives quoted by US media warn that if a 17-day standard for major releases becomes widespread, global box office revenue could plummet even further in just three years, forcing the closure of less profitable theaters and reducing the diversity of films on offer.
In Europe, where regulatory frameworks tend to be more protective of exhibition (especially in countries like France, Italy, and Spain), it's possible that regulators will impose limits or conditions on these very short release windows, particularly if they are deemed to harm competition or cultural diversity. Netflix's acquisition of Warner Bros. itself is expected to face intense scrutiny in Brussels and other capitals.
The fear among cinema chains, both in the United States and Europe, extends beyond the short term. If theatrical windows are drastically shortened, it complicates release planning, reduces the impact of word-of-mouth marketing, and diminishes the opportunity for a film to gain traction in theaters . Titles that have historically thrived by remaining in theaters for weeks or months would see their box office potential drastically reduced.
At the same time, the potential disappearance of rentals and digital purchases —intermediate stages that often fall between theatrical release and subscription streaming— would leave studios and cinemas with fewer revenue streams. Without physical editions or premium video-on-demand windows, the Netflix catalog would become the only legal way to watch certain films, with the added risk that if a title is ever removed, it will be difficult to access it officially.
Netflix's role, Sarandos' promise, and the precedent of Stranger Things
Netflix is ​​trying to downplay the controversy. Ted Sarandos has publicly insisted that the company doesn't buy a studio to "damage its value" and that there is a commitment to maintaining Warner's theatrical releases with "standard industry timelines." At the same time, in other statements, he has argued that release windows should "evolve" and be "more audience-friendly," a message many interpret as meaning "getting films on the platform sooner."
Sources cited by Deadline explain that, internally, the 17-day figure aligns with how Netflix already handles certain original productions. Typically, their films only appear in theaters to meet award eligibility requirements , and even then, only in a limited number of theaters and for the shortest possible run. Recent examples, such as 'Frankenstein' and 'Knives Out: From Among the Dead,' had an almost symbolic presence in theaters: many viewers weren't even aware they were playing in cinemas.
The other major precedent being closely scrutinized is the Stranger Things 5 ​​finale , which Netflix decided to release simultaneously on its platform and in select theaters across the United States. That move, presented by the company itself as an "olive branch" to exhibitors and a "trial balloon" to gauge audience response, yielded a striking statistic: it's estimated that the theatrical release grossed between $25 and $30 million in a single day , even surpassing a major release like 'Avatar: Fire and Ashes' during the same period.
Paradoxically, that money didn't go directly to Netflix , as the distribution agreements were designed as a gesture toward theaters. But the experiment makes it clear that there is significant economic potential when the appeal of a major title is combined with the big-screen experience, even when the release coincides with streaming . Previous cases like the Gentleminions phenomenon illustrate this. Precisely for this reason, many are questioning whether it makes sense to so aggressively limit the theatrical run of future Warner blockbusters.
Sarandos's ambiguity fuels distrust. He once went so far as to call theatrical releases "an outdated idea" and expressed his conviction that phenomena like the famous Barbenheimer would have had "the same cultural impact" if they had gone directly to Netflix. Given this track record, promises to respect "usual" release schedules are met with skepticism by both exhibitors and filmmakers.
Warner Bros, its franchises and the impact on major productions
Warner Bros. is no ordinary studio. For decades, it has maintained a strong tradition of theatrical releases and, year after year, places some of the most important titles on the global box office, many of them part of the highest-grossing franchises . In the last season, the company has added major hits with films like 'A Minecraft Movie', 'F1: The Movie', and 'Superman', all of which have grossed over $600 million worldwide, and are part of the ecosystem of powerful franchises that keep cinemas running.
Looking to the near future, the development catalog includes highly anticipated productions such as Man of Tomorrow , the new installment in the Superman universe scheduled for July, and The Hunt for Gollum , linked to The Lord of the Rings and planned for December 2027. It is precisely these types of releases that worry theater chains: if they could only exploit them exclusively for 17 days, or if they had to share them very soon with the Netflix catalog, the blow to the box office could be devastating.
The concern also extends to other brands and universes linked to Warner, such as DC, the franchises associated with HBO, and the Harry Potter universe . All of these are key components of cinema programming in Spain and the rest of Europe, especially during peak seasons like summer and Christmas. A scenario in which a large part of the audience waits only two weeks to watch these productions at home would completely change how cinemas organize their schedules and manage their revenue.
Some analysts go further and wonder if this strategy might ultimately affect subscribers as well. If subscribers are impacted and the company loses a significant portion of that revenue, Netflix might be tempted to compensate with price increases, plan adjustments, or more advertising in its subscriptions—a possibility that worries both users and regulators.
Furthermore, prioritizing streaming over other formats would solidify an ecosystem where access to films is contingent on the ever-changing catalog of a single platform. If a title disappears temporarily or permanently, viewers would be left without a simple legal alternative, given that physical releases have significantly decreased and digital rentals could lose ground in this new structure.
Regulators, competition, and the fear of near-monopoly
Netflix's acquisition of Warner Bros. Discovery, valued at around $83.000 billion according to some estimates, has more than just commercial implications. It also opens up a complex regulatory landscape. Agencies such as the U.S. Department of Justice and European competition authorities will have to analyze whether the deal concentrates too much power in a single company that already dominates the streaming market and that would also gain control of one of the most important film catalogs in history.
Meanwhile, other players like Paramount have expressed interest in acquiring Warner, further complicating the situation. Although Netflix has gained an advantage in this race, the finalization of the deal could take 12 to 18 months, or even longer, depending on objections raised by regulators and governments. During this time, pressure from exhibitors, filmmakers, and cultural associations will be intense, especially in the European Union, where the diversity of offerings and the protection of cinemas are considered top priorities.
Meanwhile, chains like AMC and other major cinema chains publicly maintain that they will not accept shorter release windows of 45 days for Warner Bros. films, foreshadowing a protracted standoff. In Europe, exhibitors' associations have already expressed concern about the potential impact of such agreements on local markets, where many independent cinemas rely on the long runs of blockbuster titles to make ends meet.
Underlying this is the fear that viewers will become increasingly at the mercy of the decisions of a small number of entertainment giants . If a single operator controls the production, distribution, and digital exhibition of a significant portion of content, the real options for choice and access to diverse works may be reduced, especially for European audiences accustomed to a certain level of regulation in the sector.
Given this scenario, it's clear that the 17-day figure is much more than just a technical detail. It represents the clash between two opposing visions of cinema : one that conceives of it as a collective experience in theaters, supported by extended theatrical runs and sustained revenue, and another that prioritizes the immediacy of streaming consumption, with near-simultaneous releases and constantly updated catalogs. Time will tell which way the scales tip, but if Netflix's approach prevails, the cinema business—in Spain, in Europe, and worldwide—will be forced to reinvent itself at breakneck speed.
