The film Blackfish, described as a psychological thriller, spearheads the increasingly vexatious issue of Whale keeping in Aquaria. Taking aim, specifically at SeaWorld, but applicable to the aquaria debate more generally, the film is described as:
Telling “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” (Official site).
