Free Willy

After the movie was released, it brought the living conditions of the star orca, Keiko (Willy) to the world's attention. His tank was too small, with too-warm chlorinated artificial salt water. Keiko suffered from a weakened immune system and a skin condition around his pectoral fins. There was a monumental effort to release Keiko. A custom tank was built in the Oregon Coast Aquarium and in 1996, the whale was flown from Mexico to Oregon. He recovered well, and was moved to a sea pen in 1998. In July 2002, Keiko was released into the wild after spending 22 years in captivity. Unfortunately he did not fully adapt to the wild and died in December 2003 in Norway. Keiko became the second oldest orca to live in captivity.

When Willy is jumping over the stone wall at the end of the movie, the bottom of the actual whale does not match the pattern of the CGI whale that lands the jump.

A disclaimer at the end of the first half of the end credits following A Donner-Shuler Donner Production reads, "No whales were harassed or mistreated during the making of this film and all scenes involving a live animal were supervised by the American Humane Association."

The first Warner Bros. Family Entertainment fanfare featuring Bugs Bunny spinning the banner appears exclusively in the VHS releases and 1990's HBO airing.
