Under the Rainbow is a 1981 American comedy film directed by Steve Rash and starring Chevy Chase, Carrie Fisher, Eve Arden, and Billy Barty.

The film received widespread negative reception with critics due to its depiction of little people and use of sight gags involving them.

In Kansas, little person Rollo Sweet (Cork Hubbert) lives in a homeless shelter while dreaming of a future in Hollywood.

In Culver City, California, near Metro Goldwyn Mayer Studios, a diverse group of people check into a hotel.

Among the hotel guests are Annie Clark (Carrie Fisher), a long-suffering employee at MGM, and her assistant Homer; an Austrian duke, duchess, and their Secret Service escort Bruce Thorpe (Chevy Chase); Nazi secret agent Otto Kriegling (Billy Barty); Kriegling's Japanese contact Nakamuri; a large group of Japanese photographers; and 150 little people, including Rollo Sweet, who have been cast as Munchkins in MGM's The Wizard of Oz.

The hotel itself has been left in the hands of the owner's incompetent nephew Henry (Adam Arkin) while the boss is out of town on business.

Fred Bauer, Steve Rash and Ed Cohen had previously made The Buddy Holly Story together.

In November 1979 the filmmakers announced they had signed a deal with the newly formed Orion Pictures to make the movie with Chevy Chase to star.

Some location filming occurred at the Culver Hotel, where the actors playing Munchkins had actually stayed during the production of The Wizard of Oz.
