As a boy, Michael Bay attached some firecrackers to a toy train and filmed the ensuing fiery disaster with his mother's camera.
Michael Bay is a filmmaker best known today for the Transformers trilogy, and for his style of producing movies, which involves copious amounts of real and CG explosions. Transformers: Revenge of the Fallen actually made news for containing the largest (real) explosion in movie history.
But Bay’s fascination with explosives began at a much younger age. In an interview with USA Today over the second Transformers movie, Bay discusses how the films are his sandbox for creation, and how his fascination with creating has always been that way. “I’d do little firecrackers on the train set... I actually set my bedroom on fire once,” Bay said.
The incident he referred to was actually so bad that the fire department had to come take a visit. All of it was because he was making a movie on his mother’s Super 8 camera about aliens. While back then such antics earned him a two week grounding, today it earns him a few billion dollars at the box office.
