Emergency officials say 16 actors dressed as zombies were injured when a platform collapsed during filming of a new movie in the "Resident Evil" series.
Toronto emergency medical spokesman Peter Macintyre says the victims' costumes made it more difficult for crews to assess the severity of their injuries.
Police Constable Wendy Drummond says the victims, who fell some 20 feet, suffered leg and back injuries. All were taken to hospitals but none of the injuries are considered life-threatening.
Cinespace Film Studios did not immediately respond to a request for comment.
"Resident Evil: Retribution" is the fifth installment of a franchise based on the popular video game series. It is not known if lead actress Milla Jovovich was on set at the time of the accident.
