Average runtime for major releases has crept upward, and the very long film — well past two and a half hours — has become notably more common. Audiences have noticed and have opinions.
The explanations offered are usually about directorial ego. There are more interesting structural reasons.
The cinema economics changed
Start with the counterintuitive one. A longer film means fewer screenings per day, which means fewer tickets sold per screen. Historically that made exhibitors hostile to long runtimes and created real pressure to cut.
That pressure has weakened, for a specific reason: attendance is lower than it was, so many screenings weren't selling out anyway. If a screen is half full, running three sessions instead of four costs less than it used to.
Meanwhile the films driving cinema attendance are event releases, and an event benefits from feeling substantial. Length has become a signal of significance rather than a cost.
Streaming trained everybody
The larger cause, and it works in two directions.
Audiences accustomed to consuming eight hours of a series over a weekend have a different relationship with duration. Three hours doesn't read as long against that baseline.
And filmmakers working across both media have absorbed a serialised approach to storytelling — multiple parallel threads, extensive world-building, characters who need establishing across a lot of screen time. Those habits transfer into features and they take time.
You can see this most clearly in films that feel like three episodes of television. Distinct movements, each with its own arc, joined together. That's a structure television taught, and it doesn't compress.
Franchise obligations
A specific and underrated driver. A film in a connected series has work to do that a standalone doesn't.
It must service returning characters, some of whom have no plot function but whose absence the audience would notice. It must set up future instalments. It must accommodate contractual appearances. And it must recap enough for viewers who missed the previous entry.
None of that is story. All of it is minutes. A film with twenty minutes of franchise maintenance is a two-hour film that runs two hours twenty.
Final cut and who has it
The traditional lever for controlling length was the studio's ability to demand cuts. That still exists for most productions.
What's changed is that a small number of directors have accumulated enough commercial standing to refuse, and those directors make a disproportionate share of the very long films. When a filmmaker's involvement is itself the marketing proposition, the studio's leverage over runtime largely evaporates.
Streaming has expanded this. A platform commissioning a film has no exhibition constraint at all — running time affects nothing operationally — so the argument for cutting is purely creative, and it's an argument the director frequently wins.
Is longer worse
Not inherently, and the discourse tends to collapse two different complaints.
One complaint is about bladders and attention, which is legitimate and practical. Three hours without an interval is a physical imposition, particularly for older audiences and anyone with a medical reason. The disappearance of the interval is a genuine accessibility issue that gets treated as a joke.
The other complaint is about padding, which is a quality judgement and often correct. A great many long films contain a tight, excellent shorter film. The subplot that goes nowhere, the sequence that restates something already established, the extended finale after the emotional climax has landed.
But there are also films whose length is doing work — where accumulated time creates weight that a shorter version couldn't. Those exist and they're the reason the argument isn't settled.
The interval question
Worth dwelling on. Intervals were standard for long films for decades and were removed largely for scheduling efficiency.
Some markets never abandoned them and audiences there find their absence elsewhere baffling. Given that runtimes have returned to lengths where intervals were once normal, reinstating them for anything over about two and a half hours seems obviously sensible.
The objections are about disrupting tension and about turnaround times. Both are real and both seem smaller than the benefit of not excluding a chunk of the potential audience from a three-hour film.
Where I land
Length should be a decision rather than a default in either direction. A ninety-minute film that says what it needs to is a wonderful thing and there are far too few of them, largely because the market has decided that short reads as minor.
That's the part I'd actually change. Not the existence of three-hour films, which is fine, but the assumption that anything under a hundred minutes must be slight. Some of the best films ever made are under ninety, and nobody would greenlight most of them today at that length.
The home viewing effect
One more factor, and it may be the largest. A three-hour film watched at home is not a three-hour commitment in the way it is in a cinema. It can be paused, split across two evenings, watched while doing something else.
Filmmakers know a substantial share of the audience will encounter the film that way, and that knowledge takes some pressure off length. A film that would have been unbearable in a single sitting for a general audience becomes viable when a third of viewers will watch it in installments.
Whether that is a good thing depends on whether you think a film should be experienced whole. Directors overwhelmingly say yes and audiences overwhelmingly do what is convenient, and the runtime has quietly adjusted to the second group.
