One film that got a lot of mention was Nolan's space-travelling spectacular Interstellar, with one fan saying, "The Docking Sequence in 15/70 was an out-of-body experience." At the same time, another proudly confessed that "Interstellar 70mm for the anniversary release is a moment I will cherish for the rest of my life!"

Within hours of Imax listing tickets for Christopher Nolan's 'The Odyssey' a year in advance, showtimes sold out and scalpers posted huge upcharges.

The unprecedented offer commenced Thursday at midnight ET for theater auditoriums equipped with the director's format of choice.
