Futurama: The Lost Adventure

The Futurama video game was released shortly after the airing of the 72nd episode in August 2003. According to David X. Cohen, the half-hour's worth of cutscenes in the game were originally written as "the 73rd episode of the original series."These cutscenes were compiled together (along with footage of the video game being played) and released as a bonus feature on the DVD release of The Beast with a Billion Backs. Renamed Futurama: The Lost Adventure, the episode tells of how the Planet Express crew prevented Mom from using Earth to take over the universe. It is rendered with PS2/Xbox-quality cel-shaded animation.
