DreamWorks later asked Mike Myers to play Shrek, whom Myers wanted the writers to re-write the script to leave no traces of Farley's version of Shrek. After Myers had completed providing the voice for the character, when the film was well into production, he asked to re-record all of his lines in a Scottish accent similar to the one his mother had used when she told him bedtime stories. After hearing the alternative voice-over, Katzenberg agreed to redo scenes in the film, saying, "It was so good we took $4m worth of animation out and did it again."
