The IMAX Promise – More Than Just a Bigger Screen
When a blockbuster advertises an "IMAX release", most movie‑goers picture a gigantic screen and booming sound. The reality is a bit more nuanced. IMAX builds its brand on three pillars: screen geometry, projection technology, and production partnership. Together they create a visual experience that can feel almost three‑dimensional, even though the image is still flat.
1. Screen shape and size
Traditional multiplexes usually project in a 2.39:1 or 1.85:1 aspect ratio – essentially a wide rectangle. IMAX replaces those dimensions with either 1.90:1 for digital presentations or 1.43:1 for film prints. The latter is almost square, which means the picture stretches further toward the top and bottom of a viewer’s field of vision. In practical terms, a typical UK IMAX auditorium (for example, the one at the O2 in London) measures roughly 59 ft tall by 79 ft wide, far larger than a conventional screen and tall enough to fill the peripheral vision of most adults.
2. Projection families – From Xenon to Laser to 70 mm
IMIMX doesn’t rely on a single projector type. The company has three distinct families, each with its own trade‑offs:
| System | Core tech | Aspect ratio | Typical resolution / colour | Where you’ll find it |
|---|---|---|---|---|
| IMAX Digital (Xenon) | Dual xenon lamps | 1.90:1 | 2K‑ish, good brightness | Most retrofit locations (Cinemark, AMC, Regal) |
| IMAX Laser GT | Two 4K laser heads | 1.90:1 (or 1.43:1 in some venues) | 4K‑level, wider colour gamut, higher contrast | Premium IMAX sites such as the O2, Manchester’s Printworks |
| IMAX 70 mm Film | 15‑perforation horizontal film run | 1.43:1 | Roughly 18 000 px per frame – equivalent to 12K+ digital | Only 32 North‑American and 41 global theatres, a handful in the UK (e.g., the Science Museum’s IMAX, the BFI IMAX in London) |
The Laser GT system is the most common “high‑end” option in the UK. It uses two synchronized 4K laser projectors to deliver brighter whites, deeper blacks and a colour space that rivals high‑end home‑theatre projectors. However, not every Laser‑equipped auditorium can push the 1.43:1 ratio; many still default to 1.90:1 because the larger screen geometry requires a specially‑designed auditorium.
The 70 mm film format is the true heritage of IMAX. Instead of the traditional vertical 35 mm frame, IMAX runs the film horizontally, exposing a frame that is 15 perforations wide – three times the area of a standard 35 mm frame. The result is a picture that can be described as “10‑times clearer” than conventional film, with an effective resolution that some engineers equate to around 12K. The downside? Each print can weigh 500 lb and cost ≈ $80,000 to manufacture, which explains why only a few theatres keep the massive projectors running.
3. Filmmakers and the IMAX workflow
IMAX isn’t a passive exhibitor; it often works hand‑in‑hand with directors from pre‑production through post‑production. When a movie is “filmed for IMAX”, the crew may use purpose‑built IMAX cameras (like the 15‑perforation 70 mm units used on Christopher Nolan’s Oppenheimer or The Odyssey). These cameras capture a larger image sensor, giving editors more visual information to crop or re‑frame for both IMAX and standard screens.
Even when a film is shot on conventional digital cameras, the director must consider the IMAX aspect ratio. As Nolan explained to the Associated Press, shooting in IMAX forces you to plan every shot carefully because the extra visual data will be displayed on a taller screen. The production team may also employ IMAX’s proprietary Digital Remastering (DMR) suite, which cleans up grain, adjusts contrast and sharpens edges before the movie ever reaches the projector.
Box‑Office Impact and the Premium‑Format Surge
The numbers tell a clear story: while overall cinema revenue in 2025 dipped to $8.9 bn (still below the pre‑pandemic peak of $11.4 bn), IMAX’s own earnings jumped ≈ 40 % year‑on‑year. In 2026, titles such as Spider‑Man: Brand New Day and The Odyssey have driven IMAX‑ticket sales to levels not seen since 2019, despite theatres operating at roughly two‑thirds capacity.
Why the boom? Premium‑format movies – think high‑budget sci‑fi, superhero epics and nature documentaries – look dramatically better on a screen that can display more detail and louder, more precise sound. For UK audiences, this translates into higher ticket prices (typically £15‑£20 for a standard IMAX showing, £20‑£25 for a Laser GT, and £30+ for a 70 mm screening) but also a willingness to book weeks in advance, especially for limited‑run events.
How Easy Is It to Find an IMAX Seat in the UK?
Globally, IMAX operates about 1,800 screens, but the 70 mm variant is limited to a handful of venues. In the UK, the main locations capable of showing 70 mm prints are:
- BFI IMAX, London – the world’s largest permanent IMAX screen (150 ft wide).
- Science Museum IMAX, London – a dedicated 70 mm theatre used for documentary releases.
- The O2 IMAX, London – primarily Laser GT, but occasionally runs 70 mm for special events.
All other UK IMAX sites (Manchester’s Printworks, Glasgow’s IMAX, etc.) rely on the Laser GT or Digital xenon systems. Ticket availability can be checked via the official IMAX website’s theatre‑finder, which lets you filter by format, price and seat‑type (e.g., premium recliner vs. standard).
Because the 70 mm projectors are essentially vintage machines – the company hasn’t built a new one in about five decades – only a small pool of technicians (estimated at ≈ 90 worldwide) know how to service them. This scarcity drives up the cost of running a 70 mm print and explains why many UK cine‑philes are willing to travel 500 + miles to see a film like The Odyssey in its original format.
Bottom Line for the UK Movie‑Goer
If you’re deciding whether to splurge on an IMAX ticket, consider what you value most:
- Screen size & immersion – any IMAX venue will give you a taller picture and a more enveloping field of view than a standard multiplex.
- Picture fidelity – Laser GT offers the best digital quality currently available, with deeper blacks and a wider colour gamut.
- Resolution & historic authenticity – 70 mm film is the ultimate format, delivering a level of detail that even the best 4K laser can’t match, but it comes with a premium price and limited showtimes.
For Android users who stream movies at home, the takeaway is that IMAX’s technical edge is still far beyond what a smartphone screen can reproduce, even with the latest HDR‑10+ displays. However, the format’s emphasis on height and immersion mirrors the trend we see in mobile design – taller aspect ratios, higher pixel densities, and richer sound via Dolby Atmos. Until your phone can fill a cinema‑sized field of view, the occasional IMAX outing remains the most effective way to experience a blockbuster the way its creators intended.
