Here’s a new digital restoration of the dazzling, dizzying movie that introduced Cinerama to the world! (Cinerama was a widescreen process in which three synchronized projectors, in three different booths, each projected one third of a single, panoramic image onto a huge, curved screen with an arc of 146 degrees.) Only three cinemas in the world are still equipped for Cinerama film projection, but thanks to newly developed “Smilebox” technology, other theaters (like us) are now able to present original Cinerama movies in their full 2.65:1 aspect ratio in a way that simulates their immersive, wraparound effect. This Is Cinerama, which is “hosted” by peripatetic writer and broadcaster Lowell Thomas, is a globe-trotting travelogue that plunks viewers into a careening roller coaster, sends them over Niagara Falls and through the canals of Venice, and sweeps them across the American West. (There are lots of other destinations as well.) No special glasses required (but seat belts recommended). Cleveland revival premiere. DCP. 127 min.
