Film reels are the physical strips of perforated celluloid—or polyester today—used to project motion-picture images in a cinema.
First Things First – How to keep your cine reels in good shape
For roughly a century, film reels served as the primary technology for video recording until digital technologies usurped the role. In an era when most movies are merely downloaded, gigantic canisters of film were once the sole method that let audiences watch movies for many decades. Perhaps you’re wondering what film reels actually involve? What materials give them their distinctive form? And just how long can they stretch? Excellent. Below you’ll find five entertaining film reel facts—ideal trivia should Jeopardy ever run a whole category on the history of video capture.
Indeed, film combines a plastic backing with a gelatin emulsion that contains silver halide crystals. During exposure, the camera lens directs light onto the film, and this illumination turns the silver crystals darker. That process produces negatives: as the silver darkens, each frame becomes the tonal opposite of the scene before the lens. Pretty neat.

“Silver-gelatine stock remains the gold standard for archival permanence—if humidity is controlled below 50 %.” —Dr Emily Andrews, BFI Conservation Manager
In earlier cinema halls, projectionists screened movies by threading very long film reels through mechanical projectors. Each of those film reels measured roughly 1 000 ft in length. By quick calculation, a reel of film approaches a quarter-mile in total span. Which brings us neatly to the next point…
If you assumed a single reel of film could accommodate a whole movie, you’d be mistaken. In practise, a reel of film holds merely about 11 minutes of a movie with sound. That figure presumes a running speed of 25 fps 〈25 fps remains today’s theatrical norm〉. Run the numbers once more and an upcoming blockbuster would have demanded roughly 18 reels of film for a single movie. Except, of course, there was a workaround…

“Platter systems let cinemas join several reels into one 6 000 ft ‘mega-reel’, reducing change-overs altogether.” —Stephen Lovegrove, Chief Projectionist, Odeon Leicester Square
The term two-reelers is, quite literally, what it sounds like. Rather than relying on a single standard, 1 000’ reel of film, two-reelers paired two segments together, trimming postage fees. Because reels were sizable and screening a single movie obliged the projectionist to switch reels mid-show, halving the number of change-overs reduced the chance of human error and improved the viewing experience. Best not to ask what Tyler Durden slipped into those reel transitions…
Yes—really. Every single movie projected in a theatre tipped the scales at roughly 60 lb overall. Each 1 000’ spool of film weighs close to 5 lb. Given that movies average about 90 minutes and 1 000’ of film yields 11 minutes of sound film, most films therefore required roughly nine film reels. Multiply nine by five and you have 45 lb. Factor in the metal or plastic reels themselves and—voilà—60 lb.

“Freighting 60 lb prints to every site produced up to 1.2 t CO₂ per feature in the 1990s.” —Albert Carbon Calculator, 2024 report Omdia
Today, films are mostly digital, zipping across the globe with digital immediacy. By contrast, movies were once captured on film and physically flown to distant territories. Were I a physicist, I might quantify the greenhouse gases saved by shifting from film to digital distribution; sadly, I’m not. Still, the reduction is almost certainly far from trivial. Entertaining as film reel trivia may be, film reels were likely environmentally unfriendly.
All told, the shift to digital is arguably a boon. So the next time you stream a digital film, give yourself a small eco-pat on the back. Recent BFI estimates put UK cinemas screening 35 mm on only 5 % of screens in 2024 BFI.
