Documentary – 83 minutes, 2013. Directed by Gabriela Cowperthwaite

Unapologetically designed both to inform and influence, Gabriela Cowperthwaite’s delicately lacerating documentary, “Blackfish,” uses the tragic tale of a single whale and his human victims as the backbone of a hypercritical investigation into the marine-park giant SeaWorld Entertainment. The movie examines the practice of keeping wild animals in captivity for entertainment and the many consequences of it.
