Disney workers dialed 911 at 7:34 p.m. to report that a cast member sustained a head injury. Varbanov was rushed to Florida Hospital Celebration Health, where he was pronounced dead at 8:53 p.m., Orange County sheriff's deputies said.
Varbanov was the the third cast member in seven weeks to die after sustaining injuries while working.
Online photos show Varbanov on the set of the Pirate's Dinner Adventure attraction in the International Drive tourist corridor. A video on YouTube shows him performing a hand-balancing act with a woman during the Pirate's attraction pre-show. Monday night, a YouTube user had posted "R.I.P. ANISLAV."
An autopsy is being performed this afternoon, said Sheri Blanton of the Orange-Osceola Medical Examiner's Office.
