As Michael Bay confirms on his website, he was recently attacked in Hong Kong on the set of Transformers 4. But Bay claims earlier reports he was injured to be false.
Yes, some drugged up guys were being belligerent asses to my crew for hours in the morning of our first shoot day in Hong Kong. One guy rolled metal carts into some of my actors trying to shake us down for thousands of dollars to not play his loud music or hit us with bricks.
Every vendor where we shot got paid a fair price for our inconvenience, but he wanted four times that amount. I personally told this man and his friends to forget it we were not going to let him extort us. He didn't like that answer. So an hour later he came by my crew as we were shooting, carrying a long air conditioner unit. He walked right up to me and tried to smack my face, but I ducked threw the air unit on the floor and pushed him away. That's when the security jumped on him. But it took seven big guys to subdue him. It was like a Zombie in Brad Pitt's movie World War Z — he lifted seven guys up and tried to bite them. He actually bit into one of the guards Nike shoe, insane. Thank god it was an Air Max, the bubble popped, but the toe was saved.
