Big Bug Man is an unreleased animated superhero television movie that was written by Simpson's Writer Bob Bendetson (who was also co-director) along with Family Guy director Peter Shin and starred the voices of Brendan Fraser and Marlon Brando. It was noteworthy for being Brando's last film (his last performance would be for The Godfather Game, or at least most of it, if not all of it). The film starred Fraser as Howard Kind, an employee of a candy factory that is bitten by bugs and becomes the superhero Big Bug Man. However, he soon becomes corrupted by the business world.

Marlon Brando had initially been approached to play the part of the evil businessman, Nicholas Dunderbeck, but Brando, who had always wanted to play a woman, decided to play the small role of the elderly candy company founder, Mrs. Sour, instead. When the directors arrived at his home to record him, they found that Brando had even dressed up in a wig, dress, gloves, and makeup to get into character. Brando was frail and required oxygen throughout the recording, but he remarked it was the most fun he had since acting in Julius Ceasar. He died the very next month on July 1st, 2004.

The film was scheduled to be released in 2006, then 2007, then in 2008. However, nothing has been heard regarding the project's release since, and its future is uncertain. Storyboard sequences have been since found online.[1][2]
