Michael Bay has confirmed online reports that he and his crew were nearly attacked on the set of “Transformers 4.”

“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,” the director wrote on his blog.

“It was like a zombie in Brad Pitt’s movie ‘World War Z’ — he lifted seven guys up and tried to bite them.”

Bay was referring to the vendor who stormed onto the set of his movie early Thursday and wielded an air conditioner unit in the direction of his head.

“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.”

Paramount also confirmed that no cast or crew member was injured in the matter.

“It took 15 Hong Kong cops in riot gear to deal with these punks,” Bay said.

“He (the vendor) actually bit into one of the guard’s Nike shoe. Insane. Thank god it was an Air Max — the bubble popped, but the toe was saved.”
