ORLANDO, Fla. (AP) — A judge in southern California has dismissed a securities fraud lawsuit brought by investors in SeaWorld.

The judge two weeks ago threw out the lawsuit brought by pension retirement programs for Arkansas state workers and Danish workers who had purchased shares in the company after its initial public offering in 2013.

The investors claimed that Orlando-based SeaWorld officials misled investors about the impact of the documentary "Blackfish" on the company's financial performance.

The documentary chronicled the life of killer whale, "Tilikum," who has been linked to the death of three people, and suggested that captivity provokes violent behavior in the enormous marine mammals. Attendance declined after the film's release.

But U.S. District Judge Michael Anello said the investors failed to show that SeaWorld officials had deliberately made misrepresentations or omissions.
