From the description:
"In the summer of 1945 war is reigning in the Pacific Rim, while in the U.S., Syms Thorley continues his life as a B-movie actor. But the U.S. Navy would like to use Thorley in their top-secret Knickerbocker Project, putting the finishing touches on the ultimate biological weapon: a breed of gigantic, fire-breathing, mutant iguanas. Thorley is to don a rubber suit that will transform him into the merciless Gorgantis and star in a film that simulates the destruction of a miniature Japan—if the demonstration succeeds, the Japanese will surrender, sparing thousands of lives; if it fails, the mutant lizards will be unleashed. Godzilla devotees and history buffs alike will be fascinated by this conspiratorial secret history of a war, a weapon, and an unlikely hero who will have to give the most convincing performance of his life."
