• Crepe, silk, cotton, and a couple of actors in West Side Story.

Though it was surely designed with the purpose of capturing landscapes and towering sets, I’m most impressed with 70-millimeter film when it’s used to magnify the very small. Some of my favorite images of the Music Box Theatre’s 70-millimeter festival (which continues through Thursday) have been close-ups or medium shots of relatively banal textures: the unmatted split ends of Dick Van Dyke’s hair in Chitty Chitty Bang Bang; grains of sand in The Master; chipped paint on brick walls in West Side Story, as well as the hanging fabrics in the dress shop of that film; bone, rock, and fur in 2001: A Space Odyssey. The high-resolution film renders these things with such specificity that even minute details appear to have been prearranged. Nothing seems like the product of chance.
