Filmmaker Michael Bay has opened up about being attacked on the set of "Transformers: Age of Extinction" in Hong Kong.

The director was assaulted by several men on Thursday, who demanded $12,900 for the "inconvenience" caused by the movie shoot.

Bay later described the incident on his blog, telling fans he wasn't actually harmed in the incident.

He wrote: "The story... being passed around is not all true! Yes, some drugged up guys were being belligerent a**es 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 (and) threw the air unit on the floor and pushed him away. That's when the security jumped on him."
Bay called the main assailant to "a Zombie in Brad Pitt's movie World War Z", revealing he tried to use his teeth as a weapon and bite into his victims.
He added, "It took seven big guys to subdue him... 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.
"Then it took fifteen Hong Kong cops in riot gear to deal with these punks. In all, four guys were arrested for assaulting the officers. After that, we had a great day shooting here in Hong Kong."
