How widescreen reshaped cinema from CinemaScope to IMAX on Blu-ray

Three thin black bars across the top, three across the bottom. Most viewers under forty hardly notice them anymore, yet for decades those bars were the unmistakable signature of a film composed for a wider canvas than the broadcast standard could carry. The story of how the screen got so wide runs from Henri Chrétien's 1950s anamorphic lens to the towering pixel dimensions of modern IMAX discs.

That trajectory passes through Cinerama projection booths, the hiss of magnetic sound, and the format wars fought in loungerooms from Sydney to Perth. Along the way, ratios split, merged, and refused to stay dead. Even today, collectors in suburbs from Fremantle to Fitzroy argue about whether the pillar-boxed German import of a 1965 epic is preferable to the open-matte Japanese laserdisc.

For Australian audiences, the wider-format story is also tangled up with peculiar distribution networks, the cautious rulings of the Australian Classification Board, and the stubborn persistence of independent video stores. Specialist retailers whose store info pages still list tens of thousands of discs online are a useful reminder that physical media, when preserved properly, still carries the original theatrical aspect ratio.

The birth of widescreen: CinemaScope storms Hollywood

In 1953, 20th Century Fox unveiled Henri Chrétien's anamorphic system under the trade name CinemaScope. The premise was simple: a single 35mm frame, squeezed horizontally by cylindrical lenses during shooting, was unsqueezed in the theatre by an inverse lens on the projector. The result was a 2.55:1 picture, dramatically wider than the 1.37:1 standard that had governed screens since the dawn of sound.

Fox had lavished money on the patents, and rival studios scrambled to respond. Cinerama, developed by Fred Waller and premiered in 1952, used three synchronised cameras to wrap nearly 146 degrees around the audience. Todd-AO offered a single-lens 70mm alternative with enormous resolution, while MGM championed Camera 65, later refined into Ultra Panavision 70. Paramount pushed VistaVision, a horizontal 35mm process best remembered for special-effects work.

These competing standards battled for roughly a decade before settling into a working hierarchy. By the mid-1960s, the industry had converged on two dominant approaches: anamorphic 35mm in several flavours of squeeze, and the more expensive 65/70mm roadshow format reserved for prestige projects. Australian audiences were among the earliest international viewers, with venues in Sydney and Melbourne importing CinemaScope rigs within months of the US debut, sometimes charging a surcharge for the wider image.

Aspect ratios and the long quest for a single standard

The format chaos created real headaches for projectionists. A CinemaScope print needed an anamorphic lens and magnetic sound; a Cinerama reel required three projectors in lockstep; a Todd-AO print demanded a 70mm platter system few suburban cinemas owned. Operators occasionally left reels threaded wrong, producing films with stretched faces or vertically squeezed buildings.

Studios offered various compromises. Super 35, developed in the 1980s, allowed filmmakers to use ordinary spherical lenses while still delivering a 1.85:1 or 2.39:1 final image after mattes were added in post. Panavision kept refining its anamorphic primes until the optical flaws of early CinemaScope largely vanished. By the digital era, the working assumption was that a feature would be framed for 2.39:1 theatrical release.

Television presented a parallel problem. Standard-definition broadcasts were locked at 4:3, so widescreen films had to be cropped, letterboxed, or pan-and-scanned. Australian broadcasters adopted letterboxing relatively early, in part because local screen bodies were comfortable with the wider format. Viewers in Adelaide, Brisbane, and Hobart who grew up watching foreign films on SBS or the ABC still remember discovering that a frame intended for the big screen could be approximated at home.

VHS, Laserdisc, and the home aspect ratio wars

When JVC's VHS and Sony's Betamax first reached Australian loungerooms in the early 1980s, the wider-than-television image was treated as a problem to be fixed rather than preserved. Studios routinely commissioned pan-and-scan versions, cropping the original 2.39:1 frame on both sides to fill the 4:3 screen. The result, visible on early VHS rentals in suburban stores from Sydney to Melbourne, was a butchered composition where characters looked at things off-screen.

Laserdisc, championed by enthusiasts who imported players from Japan and the US, was the first home format to offer true letterboxed presentation. A dedicated network of collectors, including members of the Australian Laserdisc Society, paid premium prices for special editions that preserved the 2.35:1 theatrical image with chapter stops for intermission reels. Laserdisc never broke through here the way it did in Japan, but its commitment to faithful presentation set expectations the later DVD format would inherit.

DVD itself, launched in 1997, finally settled the home aspect ratio argument for most consumers. Anamorphic widescreen, often called 16:9 enhanced, let discs deliver full horizontal resolution to widescreen televisions, whereas pre-anamorphic transfers wasted pixels on black bars. Australian distributors like Palace Films and Madman Entertainment were quick to commission proper 16:9 transfers for arthouse titles, recognising that local cinephiles would notice if a Vittorio Storaro cinematography was marred by inferior encoding.

The DVD boom and anamorphic excellence

The DVD era between 1999 and 2008 was the high-water mark for careful widescreen transfers. Studios finally had enough storage, 4.7GB per single-layer disc, 8.5GB for dual-layer, to dedicate genuine bit budget to the wider frame without aggressive compression. Criterion, the BFI, and various boutique labels perfected anamorphic 35mm material: natural grain, accurate colour timing, and theatrical aspect ratios faithfully preserved on every release.

Australia was an unusual market in these years. Parallel importation laws historically restricted independent imports of recorded media, which meant many local DVD releases were sourced from the same master used in the UK or the US, with Australian Classification Board ratings (G, PG, M, MA15+, R18+, occasionally Refused Classification) applied. Some titles arrived truncated or edited, prompting cinephiles to seek imports through a grey market of traders, swap meets, and weekend market stalls.

Personal recommendation defined the local video store during this period. Counter staff at long-running Melbourne institutions, some still operating on Brunswick Street, would weigh in on whether a film deserved the anamorphic treatment or had been given a botched 1.78:1 crop. These conversations shaped a generation of Australian viewers who came to recognise the difference between a proper theatrical presentation and a chopped-up broadcast master.

Blu-ray, HD DVD, and the high-definition widescreen era

The format war between Sony's Blu-ray and Toshiba's HD DVD played out between 2006 and 2008, with Blu-ray eventually winning once major studios consolidated behind it. Both formats offered 1920x1080 high-definition resolution, which for the first time brought the wider 2.39:1 frame into the home with something approaching theatrical clarity. A Blu-ray could store 25GB on a single layer or 50GB on dual-layer, enough to preserve a film at its original aspect ratio without visible compression artefacts.

For widescreen purists, Blu-ray normalised the inclusion of the original theatrical ratio as a default rather than a special feature. Limited editions, of the sort still catalogued through resources like vintage media shop inventories of laserdisc memorabilia and rare pressing references, increasingly offered higher frame rates, lossless audio, and bonus material drawn from the production process. Australian fans ordered many of these directly from overseas, navigating parallel importation rules and classification requirements.

Blu-ray also introduced the first consumer-grade 3D presentations and the gradual rollout of 4K Ultra HD Blu-rays beginning in 2016. 4K UHD discs deliver 3840x2160 pixels, roughly four times standard Blu-ray resolution, while keeping the wider aspect ratio intact and adding high dynamic range and expanded colour gamuts. Anyone who first saw "Lawrence of Arabia" or "2001" on UHD recognised immediately that the wider frame had always been the point.

IMAX on disc: bringing the giant frame home

IMAX began as a 15/70mm film format developed by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw for the Osaka World's Fair in 1970. The 70mm horizontal gauge was run vertically through the camera, producing a frame roughly three times the size of a conventional production still. Early IMAX venues were purpose-built theatres with five-storey screens, designed less for narrative cinema than for documentaries like "To Fly."

The shift to feature filmmaking, beginning with "Apollo 13" refitted for IMAX in 2002 and accelerating through Christopher Nolan's "The Dark Knight" and later films, gradually created demand for home video presentations that preserved the expanded 1.43:1 or 1.90:1 IMAX aspect ratio. Blu-ray 3D offered early experiments, but the real breakthrough came with 4K UHD Blu-ray, which finally had the storage to retain IMAX-framed sequences at full resolution without forced reframing.

Many IMAX-enhanced discs present the wider footage open-matte to fill the 16:9 screen, while some special editions offer a 1.78:1 presentation showing the full IMAX frame top to bottom. Australian collectors driving between Brisbane and the Gold Coast for weekend meet-ups have been known to bring portable monitors specifically to confirm which transfer is which, before committing to an imported limited edition.

The streaming era cannot erase the wider frame

Streaming platforms have largely defaulted to 2.00:1 or 1.78:1 crops to accommodate the 16:9 television, a compromise that has crept into new productions too. Some directors, notably Christopher McQuarrie and Denis Villeneuve, have publicly insisted that their films never be reframed for streaming, and certain titles on premium tiers now present a 2.39:1 image letterboxed within the 16:9 frame. Others continue to be reframed aggressively, sometimes invisibly, with cinematographers forced to recompose shots originally framed for a wider field of view.

For Australian viewers who grew up through VHS, DVD, and Blu-ray, the disappearance of theatrical framing at home is genuinely felt. Weekend browsing at a local video store remains one of the few remaining ways to find older titles still presented in their correct aspect ratio, especially imported or out-of-print editions. Independent shops persist in pockets of Sydney, Melbourne, Perth, and Adelaide, and a small online network continues to specialise in region-free hardware and PAL DVD transfers sorted by classification and ratio.

Tracking down a particular out-of-print edition can feel like detective work, and dedicated staff are invaluable when a specific aspect ratio is non-negotiable. Customers hunting rare discs often arrive with screenshots, runtime data, and pressed-disc identifiers ready. The wider frame survives, even now, wherever someone insists on watching a film the way it was meant to be seen.
