There’s a new documentary coming to theaters that’s looking to change the way we look at those beautiful killer whales we see at Sea World. Blackfish takes a look at the killer whale entertainment industry, specifically the case of one orca who killed his trainer in 2010.

The killer whale at the center of Gabriela Cowperthwaite‘s chilling expose is Tilikum, who’s been involved in the deaths of three people while in captivity at Sea World in Orlando, Florida. The last death was that of 40-year-old Dawn Brancheau who was drowned in the Shamu tank after Tilikum pulled her by the pony-tail possibly mistaking it for fish.

The doc expands its focus by interviewing those who captured and cared for captive orcas on their route to sea parks, and what we see is quite terrifying and emotional. Experts also lend a word, mostly saying that keeping these brilliant and enormous creatures in tiny tanks is likely to create some psychological trauma. Here’s that trailer:

The film first premiered at Sundance, and thus far has gained some rave reviews. Some have compared it to the award-winning The Cove, which highlighted the number of dolphins killed in Japan by the country’s whaling industry. Blackfish seems to have that Award-winning vibe to it as well. The documentary hits theaters July 19th through Magnolia Pictures.
