Based on a true story
The film The Beast from 20,000 Fathoms was based on a real life incident in 1952 where a three foot tall lizard ran amok in New York, causing thirty dollars worth of damage and biting several people, three of whom needed medical attention.
Rampaging lizards – some radioactive and fire-breathing – have long been a problem for the city, which was built over an ancient dinosaur mating ground.
