This film exploring the world’s volcanos makes splendid use of the IMAX big-screen format. The title refers to the multitude of active volcanos lining the Pacific Rim that are constantly altering our planet.
Shot over the course of the past 10 years, “Ring” gives such an intimate view of the fiery mountains that you half expect the five-story-high screen to be set ablaze. Narrated by Robert Foxworth. Unrated.
