HORROR footage shows the moment a grizzly bear mauled his trainer to death after a “simple routine” went horribly wrong.
Stephen Miller passed away minutes after the huge beast, known as Rocky, ripped out his neck as shocked onlookers rushed to his aid.
The video, which has remerged on the 14th anniversary of the attack, showed the duo square up as they attempted to shoot a commercial for a staged wrestling match.
Rocky was a trained animal and had previously performed on screen, having appeared as "Dewey the Killer Bear" in the Will Ferrell film Semi-Pro just several weeks earlier.
But during preparation for the staged attack stunt, the huge beast became confused and proceeded to bite Stephen on the neck and pin him to the ground.
His cousin, Randy Miller, quickly jumped on the scene and struck Rocky with a cane as his colleagues doused it with pepper spray.

Stephen then hobbled to his feet and stumbled off camera – only to die minutes later from a pierced jugular vein and artery.
Speaking after the incident, Randy said that he was overwhelmed with grief as he came to terms with the tragic loss.
“It’s ... killing me. We were brothers,” a tearful Randy Miller said at the time.
“It happened so fast. We did what we had to do to stop the bear. It took a matter of seconds to get him off, but it was too late.”

Despite the travesty, Randy described Rocky as a “loving, affectionate, friendly, safe bear” as an official probe was launched into the incident.
Animal right activists called for Rocky to be spared euthanasia and to be allowed to retire to a zoo.
The California Department of Fish and Game eventually concluded that Miller’s death was accidental as the bear’s life was spared.
Rocky was sent to live out the rest of his days under tight restrictions as it was ruled that he could no longer have contact with any humans other than his trainers.
