Blackfish the movie has opened in theatres worldwide. The documentary looks at the incident with SeaWorld’s Tilikum, a 12,000 pound orca, in 2010 as well as other captive whales. It explores what may have caused Tilikum to kill three people, including SeaWorld trainer Dawn Brancheau.

From the official website:

“Blackfish tells the story of Tilikum, a performing killer whale that killed several people while in captivity. Along the way, director-producer Gabriela Cowperthwaite compiles shocking footage and emotional interviews to explore the creature’s extraordinary nature, the species’ cruel treatment in captivity, the lives and losses of the trainers and the pressures brought to bear by the multi-billion dollar sea-park industry.”
