Based on the character created & owned by the Japan-based Toho Co., Ltd.

The plot of the film involves a giant mutated iguana from the Southern Pacific roaming around New York City. The monster lays eggs inside Madison Square Garden which hatch into miniature, T-Rex-like creatures. This tended to make the film somewhat reminiscent of Jurassic Park, as the baby Zillas are reminiscent of Velociraptors.
