The Ontario Ministry of Labor is conducting an investigation into an accident on the set of ‘Resident Evil: Retribution 3D’. The film, currently being directed by Paul W.S. Anderson, is shooting in Toronto with lead star Milla Jovovich. According to The Hollywood Reporter, 16 cast and crew members fell into a five foot hole on the location, causing 10 of the zombies from the cast to be hospitalized. After help arrived on the scene, Ambulance staff was said to have had trouble differentiating between the real blood and the fake.

The accident, that occurred this past Tuesday, was said to be due to a platform that shifted at the Cinespace Kipling Studio, leaving a large hole. Davis Films, Impact Pictures and Constantin Film International issued a statement about the accident. “It is with regret that we confirm this unfortunate accident. The thoughts of everyone involved in the production are with those who have been injured, and we hope that all have a quick and complete recovery.”

Injuries reportedly ranged from cuts to bruises, and back issues. The multi-million dollar franchise is said to still be filming while investigators continue to look into the incident. If “imminent danger” is found they have threatened to close down filming. Resident Evil: Retribution 3D is due out in theaters on Sept. 14th 2012.
