Stewie Griffin: The Untold Story

Stewie Griffin, the infant son of the Griffin family, becomes convinced that Peter is not his real father. After seeing a man who resembles him on television, he sets out with the family dog, Brian, to track the man down. What begins as a search for his biological parent turns into a journey that brings Stewie face to face with an older version of himself, and with a future that differs from what he had pictured.

The film is an animated comedy directed by Pete Michels, written by Alex Borstein, Gary Janetti and Chris Sheridan, and produced by Kara Vallow. It grew out of the television series Family Guy and was made by Fuzzy Door Productions with 20th Century Fox Television and Fox Television Animation. The voice cast is led by Seth MacFarlane as Stewie, alongside Alex Borstein, Seth Green, Mila Kunis and Patrick Warburton, with Lori Alan voicing the news anchor Diane Simmons among a credited cast of 41 performers. Running 88 minutes, it mixes comedy and adventure with science fiction.

On IMDb it holds a rating of 7.5 from around 34,000 votes, while on TMDB its rating is 6.9 from 444 votes. The large gap in vote numbers between the two reflects how much wider the film's audience is on IMDb, and both scores sit in the upper-middle range for an animated comedy spun off from a long-running series.
