Michael Bay's movie sets are widely known for their big, explosive action sequences but on Thursday, the filmmaker became the action in a bizarre incident on the set of his latest movie, "Transformers: Age of Extinction."

According to a Paramount spokesman, a man ("allegedly under the influence of narcotics)", stormed on set and swung an air conditioner unit at Bay's head.

Bay, who was not injured, then "ducked and wrested the air conditioner from his attacker, preventing what could have been a serious accident."

Earlier reports suggested the director had been attacked by two brothers in Quarry Bay, where the Mark Wahlberg-starrer is currently shooting, which Paramount strongly denied.

"Contrary to several erroneous news reports made today, Bay did not get hurt in a fight on set," the studio said.

After the man was subdued by Bay, Paramount stated that police scuffled with the air conditioning wielding suspect as well as two other assailants before arresting the three men.

No cast or crew members were injured in the incident.

"Transformers 4," which has been filming for the past four months, hits theaters June 27, 2014.
