Keiko was a male orca captured in the Atlantic Ocean near Iceland in 1979. He was best known for his portrayal of Willy in the 1993 film Free Willy. In 1996, Warner Bros. and the International Marine Mammal Project collaborated to return Keiko to the wild. After years of preparing Keiko for reintegration, Keiko was flown to Iceland in 1998 and in 2002, became the first captive orca to be fully released back into the ocean. On 12 December 2003, he died of pneumonia in a bay in Norway at the age of 27.
