Using the tragic deaths of three people killed by SeaWorld bull orca Tilikum between 1991 and 2010 as a focus for exploring the practice of holding killer whales in captivity, this sensitive documentary illustrates how their intelligence and sometimes friendly nature can operate as a deadly illusion. This film not only reviews the unfortunate circumstances of the Tilikum cases, but probes the moral issues connected to the employment of these animals for entertainment purposes. 83 min. Widescreen; Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH), Spanish; audio commentary; featurettes.
