A supposedly tame grizzly bear Will Ferrell's character wrestled in his latest movie has mauled its trainer to death at a California facility for exotic animals.
Three experienced handlers were working with the giant 2.3 metre tall bear called Rocky when it bit 39-year-old Stephan Miller on the neck.
The handler is the cousin of facility owner Randy Miller who doubled for Ferrell in the film.
Pepper spray was used to subdue and contain the bear but no decision's been made on the animal's future.
The bear weighs 317 kilograms and appeared in a scene in the comedy Semi-Pro in which Ferrell's character wrestles a bear to promote his basketball team.
