>Brando was originally asked to be the voice of Nicholas Dunderbeck, but Brando thought it would be fun to voice the old lady Mrs. Sour instead.
>Mrs. Sour is only in three scenes, so it took only one day to record the voice of this character.[5] According to the director Bob Bendetson, Brando wore a blond wig, a dress, white gloves, and full makeup while recording the voice of Mrs. Sour. Bendetson believes this was part humorous, and part wanting to get into character. Bendetson said "About halfway through he took off the wig because he was getting too hot."[5] According to the film's executive producer Gabriel Grunfeld, Brando described the part as "the most fun I've had since playing Julius Caesar." Grunfeld said that even though Brando was frail, he was full of energy and invention.[4]
>The recording took place in Marlon Brando's home, on June 10, 2004. Brando was on oxygen six hours a day.[5] He died the next month, on July 1, 2004.
