Jiminy crickets! Irradiated wheat and produce are turning normal grasshoppers into giant, man-eating monsters that are marching (hopping?) on Chicago. Can scientist Peter Graves and reporter Peggie Castle stop them before they swarm all over Wrigley Field? Bert I. Gordon ("The Amazing Colossal Man") directs this "big bug" sci-fi fave. 73 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital mono; audio commentary; theatrical trailer.
