Moviegoers looking up Christopher Nolan's "The Odyssey" are seeing two similar but not identical theater labels: IMAX and IMAX 70mm. The distinction matters because the names point to different ways a film is projected, even though both are tied to the premium large-screen IMAX experience.
In simple terms, IMAX is the broader exhibition format most people encounter at modern multiplexes. It usually refers to an IMAX-branded auditorium with a large screen, upgraded sound, and presentation designed to make the image feel bigger and more immersive than a standard screening. IMAX 70mm, by contrast, refers to a film-based version of the format that uses 70mm film projection rather than the more common digital setup.
That is why "The Odyssey" can be advertised in both formats at the same time. Many theaters can show a movie in IMAX, but only a smaller number are equipped to handle IMAX 70mm. For audiences, that means the digital IMAX option is generally easier to find, while IMAX 70mm is the more specialized presentation that film enthusiasts often seek out when available.
The renewed interest in the difference comes from Nolan's reputation for large-format filmmaking and from the movie's status as a major format-driven release. For viewers deciding between the two, the practical choice often comes down to access: IMAX is the more widely available premium option, while IMAX 70mm is the rarer, film-projection version that some fans see as the closest to a showcase presentation.
