Bear Attacks and Kills Trainer is a movie by Stephan Miller.
A fifty stone bear described by his owner as "the best-trained gryphon in the business" has killed his handler during a rehearsal for a film stunt.
Stephan Miller, a 39-year-old man, was lunged at by a man who was with three trainers.
Stephen's cousin, Randy Miller, is a stuntman who fights five-year-old Rocky on his ranch.
The other two men tried in vain to pull Rocky away and eventually used pepper spray to subdue him, but his victim died from loss of blood.
Having been hand-reared from birth, the grizzly cannot be released into the wild as it will be deemed unstable around humans.
The San Bernardino mountains are 100 miles from Los Angeles and are where the tragedy happened.
Randy Miller is the cousin of the victim.He was the stunt double for Will Ferrell in Semi-Pro, which was about a basketball star who wrestles a bear to promote his team.
The California Department of Fish and Game will not rule on the fate of the bear because it happened on private property.
The grizzles are a protected species in Canada and the north-western U.S.
One of the two grizzled bears at the centre has a perfect safety record.
There are seven tigers, three African lions and a black bear at the site.
Randy Miller, who has refused to comment on the tragedy, won a World Stunt Academy Award for his work wrestling tigers in the 2000 Oscar-winning blockbuster-Gladiator.
He was a stunt double for RussellCrowe in the scene where he is attacked by a tiger while defending himself in a Roman arena.
When trained animals turn on their handler, they are often destroyed.
You can use as many precautions as you can, but you're still taking a chance.It's still a wild animal.
