Despite its long pre-development, the Family Guy movie is still on the way. The show first premiered in 1999 and features an animated family of five and their dog, Brian. They live in a small town and constantly get into ridiculous antics that reflect politics, raunchy topics, and anything related to comedy. Despite efforts by the show's creator, Seth MacFarlane, there has not been a feature-length movie since Stewie Griffin: The Untold Story in 2005.
