In 2013, SeaWorld's treatment of killer whales in captivity was the basis of the movie "Blackfish", which documents the history of Tilikum, a killer whale captured by SeaLand of the Pacific, later transported to SeaWorld Orlando who has been involved in the deaths of three people. In the aftermath of the release of the film, Martina McBride, 38 Special, REO Speedwagon, Cheap Trick, Heart, Barenaked Ladies, Trisha Yearwood and Willie Nelson canceled scheduled concerts at SeaWorld parks. SeaWorld disputes the accuracy of the film, calling it “propaganda” and “emotionally manipulative”. It has spent $15 million on an advertising campaign countering the allegations and emphasizing its contributions to the study of whales and their conservation.
