    On December 12, 2003, Keiko, one of the most famous killer whales in the world, died of pneumonia in a Norwegian fjord. He was 27 years old.
    Keiko was the title character in Free Willy, a movie about a boy setting a captive whale free. Free Willy brought attention to the conditions of Keiko’s own captivity in a Mexico City, Mexico, amusement park. Keiko was captured in the North Atlantic Ocean as a calf. He grew up in aquariums in Iceland and Canada before being sold to the facility in Mexico. 
    Many people and organizations advocated for Keiko’s return to the wild. Some marine biologists, however, were skeptical about the plan. They thought Keiko was far too acclimated to living with people and would be unable to adjust to life in the open ocean. 
    Nonprofit organizations and multinational corporations bought Keiko from the Mexican aquarium. Keiko was transported to an aquarium in Oregon, and then to a facility in Iceland, where he was trained to live among wild orcas. 
    Keiko never adjusted to life in the wild. He lived the rest of his life around Norwegian fjords, interacting with residents and tourists.
