You know, its kind of funny when you look back at Bad Boys compared to now. It was a movie that was made for only $9 million. Bay had to fork out his own money of $30,000 to pay for a scene he wanted. And he had to use his own Porsche for Will Smith's character to drive.
And now fast forward 14 years later. He's got his own jet, drives a Ferrari, and can get $240 million (Transformers 2) films greenlit.
That in itself is inspiration. In my opinion, he holds the title of greatest visionary director in the action genre. A title that was once held by John Woo, in my opinion.
