Let's hope they don't find out about fishing....

Found on a trivia page for the Shawshank Redemption:

'The American Society for the Prevention of Cruelty to Animals monitored the filming of scenes involving Brooks' crow. During the scene where he fed it a maggot, the ASPCA objected on the grounds that it was cruel to the maggot, and required that they use a maggot that had died from natural causes. One was found, and the scene was filmed.'
