Documentary details death of trainer Dawn Brancheau in Orlando

ORLANDO, Fla. - The creators of a critical documentary targeting SeaWorld Orlando have released a new trailer two months ahead of the movie's wide release.

"Blackfish" focuses on Tilikum, the whale responsible for killing 40-year-old SeaWorld trainer Dawn Brancheau in 2010. The film's director, Gabriela Cowperthwaite, seeks to show what she claims are "devastating consequences" of keeping killer whales in captivity.

SeaWorld Orlando leaders told Local 6 in January they could not comment on the film until they saw it.

"However, we set the highest standards for the care of our animals," SeaWorld leaders told Local 6.

In the new trailer, viewers hear the 911 call that came in to the Orange County Sheriff's Office following Brancheau's death.

"We need 'S.O.' to respond for a dead person at SeaWorld," the caller says in the trailer. "A whale has eaten one of the trainers."

The trailer also highlights the documentary's focus on Tilikum's capture and the life of a whale in captivity. It contains home video showing people circling whales and capturing them from the ocean.

The trailer also shows video of the "storage modules" where the whales were allegedly held. Multiple people who are interviewed in the trailer claim the small quarters of the modules cause a state of psychosis in the whales, making them more aggressive.

"Blackfish" debuted in January 2013 at the Sundance Film Festival. It will be released in theaters July 19, according to the documentary's website.
