review for Crack in the World on AllMovie

Doomsday movies abound, but few are as offbeat as this one. It tells of a runaway fault line that threatens to circle the earth and crack it in two like an eggshell. Far-fetched? Yes. Good fun? You bet. The trouble begins after scientists explode an atomic bomb underground to tap an unlimited supply of geothermal energy. But instead they trigger a cataclysm. While the crack girdles the earth, there's time for romance and frantic 11th-hour attempts to save humanity. Dana Andrews heads the cast as Dr. Stephen Sorenson, a scientist in a control center monitoring the progress of the crack opened by the explosion. He and co-stars Janette Scott (Dr. Maggie Sorenson), Kieron Moore (Dr. Ted Rampion), and Alexander Knox (Sir Charles Eggerston) all perform capably as they attempt to forestall doomsday with crack-stopping schemes. Although Crack in the World is a B-movie, it has an intelligent script that relies more on judicious pacing and suspense-building than on special effects. Consequently, it is superior to so-so doomsday flicks such as Asteroid (1997), Meteorites (1998), Armageddon (1998), and Independence Day (1996). Experts in plate tectonics -- a science that studies the strata making up the earth's outer shell -- may pooh-pooh the plot as implausible. Then again, they just might enjoy seeing Mother Nature throw a tantrum.
