Mothra vs. Godzilla (1964)

Mothra vs. Godzilla (1964) A greedy developer has placed huge machines to suck dry a part of the ocean near Tokyo so he can put luxury condos there. After a storm, a giant egg washes up on the beach nearby and is immediately put on public display. The developer's plans go awry when he disrupts Godzilla's rest and the monster goes stomping through Tokyo again. It's up to the elderly Mothra, and then to its two offspring, to save Tokyo from destruction.
