More than 20 years ago, I sat in Stan Brakhage’s office at the University of Colorado, handling original frames of 65mm IMAX film stock that the avant-garde filmmaker had hand-painted with swirling layers of colour. He explained that IMAX had commissioned him to create an abstract film specifically for presentation on the huge screens of their theatres. It was a great idea, and I wondered when the film had screened. Never, Brakhage told me. The IMAX people eventually lost interest in the idea, and “Night Music” was shown instead in 16mm prints, drastically reduced from the large-gauge film stock. Although IMAX were bold enough to approach Brakhage in the first place, the company got cold feet when it came time to actually exhibit non-narrative cinema—even for only 30 seconds!—for a paying audience.
