Cinema etiquette: the unwritten rules

There's no sign listing all the rules. There's no exam you have to pass before walking into an auditorium. But anyone who has ever sat in a packed theatre next to someone who couldn't put their phone down knows: there are unwritten rules, and breaking them is a crime against humanity. Time to write them down.

The phone: the big conversation

Let's start with the biggest pain point. The phone. In a world where we spend an average of more than four hours a day staring at a screen, cinemas ask something almost otherworldly: put it away. Two hours. That's all.

It's not just about the sound — though a ringing phone during a film's emotional climax sounds like an alarm going off in a hospital. It's also about the light. A glowing phone screen in a dark auditorium is clearly visible to everyone within ten rows. You think you're being discreet. You're not.

The rule is simple: flight mode or silent, screen facing down or in your pocket. If you genuinely cannot go two hours without it — and that, incidentally, is a conversation worth having — consider whether the cinema is the right outing for you right now.

Talking during the film

Some people think out loud. They narrate what they see. "Oh, he's going to do it!" "Didn't see that coming!" "Wait, who is that again?" This behaviour is understandable in your own living room. In a cinema, however, it belongs to your neighbour alone — and it is unwelcome.

There is a difference between an unexpected laugh, a collective sigh of relief, or a spontaneous reaction to a jump scare — that is shared experience, that is cinema — and a running commentary on a film that someone else is also trying to watch. The former enriches the experience; the latter disrupts it.

The exception: comedy screenings or specific interactive events where audience participation is expected and encouraged. At a special Rocky Horror Picture Show screening, shouting along is part of the deal. At Oppenheimer, rather less so.

Arriving late

The trailers begin, you find your seat, you settle in. Then the film starts, the lights go down, and in an ideal world everyone is quietly in place. In reality, someone always stumbles in ten minutes after the film has started, large soft drink in hand, elbowing their way along a row and waking everyone up in the process.

Running late happens to everyone occasionally — traffic, parking, the popcorn queue that was longer than expected. That's not the problem. The problem is the response: it doesn't need to involve maximum noise, confusion, and apologies in every direction. Slide quietly to your seat, sit down, done.

The food question

Eating at the cinema is a universal given and in most cases perfectly acceptable. Popcorn is the primal food of the cinema and makes its own noise — that's part of the deal. But there is a world of difference between a bag of popcorn and a crinkly foil wrapper that someone is trying to open in slow motion. Or eating crunchy crisps during the quietest, most delicate moment in the film.

The unwritten rule: whatever you bring in, make sure you can handle it quietly. A large cup with a straw: fine. A plastic bag full of individually wrapped sweets that rustle with every move: maybe save those for the interval.

The seating debate

A topic rarely discussed formally but experienced by everyone: seat stealing. You've booked seat F9. Your neighbour has F11. You're waiting for a friend who has F10. All fine so far. But what do you do when F10 is occupied by someone who "found a better spot"? And what do you do when that person refuses to move?

The rule: sit in the seat you booked. Not in a "better" spot that happens to look free — because that seat is not yours and its owner may arrive at any moment. Cinemas with reserved seating have that system for a reason.

The credits: stay or go?

This is culturally determined. In MCU culture, post-credits scenes are sacred and no one leaves their seat. At a drama or arthouse film, everyone makes their own choice. What you don't do: weave through the credits while others are still seated and watching. A quiet, respectful exit is always the right move — even if it means passing three rows of people.

In short: cinema etiquette is built on one fundamental principle. The theatre is a shared space. Your experience is just as valuable as the person next to you — and theirs is just as valuable as yours. Treat the auditorium as you would want others to treat it for you.
