What Happened to 70mm IMAX Theaters?

The journey of 70mm IMAX theaters reflects a fascinating interplay between technological advancement, artistic vision, and audience demand. Originating in the late 1960s, the 15-perforation 70mm IMAX film format quickly established itself as the gold standard for immersive cinema, known for its colossal screen size, unparalleled resolution (equivalent to 16K-18K digital), and expansive 1.43:1 aspect ratio that filled audiences' peripheral vision. For decades, these theaters primarily showcased documentaries and educational films in purpose-built venues.

The early 21st century brought a significant shift with the advent of digital projection. IMAX Corporation, seeking to expand its footprint beyond expensive, dedicated film venues, introduced digital IMAX systems (initially 2K, later 4K Laser) that could be retrofitted into existing multiplex auditoriums. While more accessible and cost-effective, these digital systems often offered a smaller screen size and a cropped 1.9:1 aspect ratio, leading some purists to dub them 'LieMAX.' This period saw a decline in the number of operational 70mm IMAX projectors, as many theaters either converted to digital or ceased operation.

A pivotal turning point arrived with director Christopher Nolan, who became a vocal champion of the 70mm IMAX format. Beginning with sequences in 'The Dark Knight' (2008) and progressively expanding its use in films like 'Interstellar' (2014), 'Dunkirk' (2017), and especially 'Oppenheimer' (2023), Nolan demonstrated the format's unique visual power for narrative features. His commitment reignited audience interest, leading to sold-out screenings and a renewed appreciation for the analog experience.

The current status, as of July 2026, is one of high demand and limited supply. Nolan's latest epic, 'The Odyssey,' released on July 17, 2026, marks a historic milestone as the first feature film shot entirely on IMAX 15-perf 70mm film. This achievement was made possible by the development of new, quieter IMAX film cameras ('the blimp' or 'The Keighley') to overcome previous noise issues during dialogue scenes. Tickets for 'The Odyssey' went on sale a year in advance and quickly sold out in many of the approximately 30-45 operational 70mm IMAX theaters worldwide. IMAX CEO Richard Gelfond has acknowledged the immense demand but stated that building new 70mm projectors is not practical, as they haven't been manufactured in about 50 years and blueprints are reportedly lost. Instead, the strategy involves retrofitting and rebuilding existing units, as evidenced by Cinemark activating three additional 70mm IMAX systems in late 2025.

The consequence is a highly exclusive and sought-after viewing experience. While the number of true 70mm IMAX screens remains small, their cultural impact, particularly for event films, is significant. The format's survival is largely sustained by dedicated filmmakers and a passionate audience willing to travel and pay premium prices for the unparalleled visual fidelity, even as the industry continues to invest in advanced digital laser projection systems that can also achieve the 1.43:1 aspect ratio.
