The Wizard of Oz is a 1939 American musical fantasy film directed by Victor Fleming. It was based on the 1900 children's novel The Wonderful Wizard of Oz by L. Frank Baum, who died twenty years before this film was released. It features Judy Garland, Ray Bolger, Jack Haley, Bert Lahr and Frank Morgan, with Billie Burke, Margaret Hamilton, Charles Grapewin.
Seth MacFarlane has stated in episode commentary that when they do Oz-related cutaways, they have to use the characters as designed in the books due to refusal by MGM to allow access to the movie's characters. This is evident when Dorothy is shown wearing silver/blue slippers instead of the movie's Ruby Red. However, she is shown wearing Ruby Slippers in "Herpe, the Love Sore".
In "I Never Met the Dead Man", when Peter goes through withdrawal of not watching TV, he has a dream based on the tornado scene in the Wizard of Oz.

Next, he sees Jeannie who transforms into Samantha from Bewitched which is similar to Mrs. Gulch transforming into the Wicked Witch of the West.
