Netflix premiere: November 11th 2013 - Blackfish (Cowperthwaite)
Magnolia Pictures are no strangers to impactful documentaries that spur debate and ruffle feathers, having previously picked up, among others, Jesus Camp (2006) and A Place at the Table (2012). Blackfish, directed by Gabriela Cowperthwaite and produced by Manuel V. Oteyza, has already 'gone national' with CNN coverage and the recent news that Pixar is changing the ending of its coming Nemo sequel as a direct consequence of its revelations about whales in captivity.
Seaworld, the site of captivity for Tilikum, has responded the film is unduly biased and doesn't to its satisfaction communicate that Seaworld "rescues, rehabilitates and returns to the wild hundreds of wild animals every year".
This is a film that explores interesting questions pertaining to man's interaction with animals, and the issue of animal captivity.
Tilikum has a wiki, the director of the movie answered questions from the internet audience on reddit (an AMA - Ask Me Anything) and you can also read more about Pixar changing its Finding Dory ending.
