A multiplex ticket now runs anywhere from £8 to £15 depending on postcode and how many dimensions the film insists on — which makes it worth knowing that free cinema never actually went away. It just stopped advertising. Between preview screenings, the BFI's free archive seats, library film nights and the volunteer film-society circuit, you can keep a weekly big-screen habit for less than the price of one multiplex visit a month.

Preview screenings: the free tickets that fill rooms

Film distributors need full rooms for preview screenings — word of mouth from an empty cinema is worth nothing — so they give the seats away. ShowFilmFirst is the main machine for this in the UK: membership is free, and it releases tickets to advance screenings, often days or weeks before general release, sometimes with a token booking fee and often with none. The catches are real but mild: screenings cluster on weekday evenings in bigger towns, tickets are first-come, overbooking means arriving early, and for the secretive releases you'll be asked to seal your phone in a pouch. In exchange you see the film before the people who'll pay £13 for it. Beyond the dedicated sites, distributors hand batches of preview tickets to radio stations and film magazines to give away — signing up to a couple of film newsletters catches those, and the competitions are usually undersubscribed because nobody believes free tickets are real anymore.

The adjacent trick is the mystery preview: several chains run a regular surprise-film night — an unnamed advance screening for roughly £6. Not free, but a preview plus a gamble for half the standard price, and the gamble usually lands on something you'd have picked anyway.

The BFI's free seats

The BFI is quietly generous once you're past the box office:

  • The Mediatheque at BFI Southbank is a room of free viewing stations wired into the national film and TV archive — thousands of titles, from lost sitcoms to century-old footage of your own town. No ticket, no charge; just turn up and take a booth.
  • BFI Player's free collection puts a large slice of that archive online at £0, no subscription.
  • If you're 25 or under, the BFI's young-audience scheme sells tickets to regular screenings at £3 — the single best cinema deal in the country for anyone who qualifies.

Your library card is a film pass

Public libraries have edged into cinema's territory from two directions. Many run free film screenings — matinees, family films in half-term, classics with tea — advertised on nothing grander than the noticeboard. And a growing number of library services offer Kanopy, the streaming platform stocked with arthouse, world cinema and documentaries, free with your library card; whether yours does takes thirty seconds on your library's website to check. Between Kanopy and BFI Player's free tier, the £0 streaming shelf is deeper than one paid service — and unlike the paid ones, the catalogue doesn't vanish at the end of the month because a licensing deal expired.

Community cinema: the £4–£6 circuit

Britain has hundreds of volunteer-run film societies and community cinemas — village halls, arts centres, converted chapels — supported nationally by Cinema For All. Tickets typically run £4–£6, programming is braver than the multiplex, and the interval ice cream is priced like it's 2005. Some run free with a donation tin. They survive on turnout, so this is the rare money-saving habit that's also a civic act: your £5 keeps the projector bulb on. Search your town plus film society or community cinema; there is almost certainly one closer than your nearest Odeon. University film societies belong in the same bracket — many sell membership to the public for the price of two multiplex tickets and then screen thirty films a year on it.

Summer and the civic screen

Every summer, councils, shopping centres and festivals put up free outdoor screens — family films in parks, sports coverage in squares, classics against castle walls. They're funded as footfall bait, which means nobody checks tickets. Listings live on your council's events page and local Facebook groups rather than anywhere sensible; the deckchair crowd found them anyway. Bring a blanket and your own popcorn — the £4.50 tub is how the paid version gets you, and out here there isn't one.

The habit, rebuilt

Stack it up: a ShowFilmFirst preview when the alert lands, a film society night a fortnight at £5, the Mediatheque or a library screening for the odd free afternoon, Kanopy at home. That's more cinema than most people watched when they were paying full freight, for under £15 a month — versus £100+ for the same appetite at multiplex prices. The films are the same. The room is sometimes better. The multiplex always needed you more than you needed it; preview season is when it admits as much, and gives the seat away.
