Stewie Griffin: The Untold Story is a 2005 direct-to-DVD adult animated comedy film set in the Family Guy fictional universe. Released on September 27, 2005, the film's main plot point concerns Stewie Griffin trying to find who he thinks is his real father after seeing the man on TV. He travels to San Francisco, only to find that the man is him from the future. The DVD contains commentaries and a sneak preview of the American Dad! Volume 1 DVD.
Fox eventually aired the film as three separate episodes for the Family Guy season 4 finale in May 2006. Fox had several scenes cut out, new scenes put in, and other scenes altered to make it only 66 minutes long. The shortened and separated versions of the three segments – "Stewie B. Goode", "Bango Was His Name, Oh!", and "Stu and Stewie's Excellent Adventure" – were aired on May 21, 2006.
