About 'Blackfish'

Blackfish traces a 39-year history of killer whales in captivity leading up to the 2010 killing of Sea World trainer Dawn Brancheau by the 12,000-pound orca, Tilikum, a whale previously associated with the death of two other people. Blackfish chillingly shows that this incident of violence is hardly an isolated one, along the way exploring the extraordinary nature of orcas, thought to be one of the most intelligent species in the animal kingdom.
