The film was shot entirely in Marin County, home of Skywalker Ranch. Much of the action was shot in a public parkland called Roy's Redwoods, which contains 300-year-old sequoias, the oldest in the area.
The film takes place between the events of Star Wars: Episode V - The Empire Strikes Back (1980) and Star Wars: Episode VI - Return of the Jedi (1983).
Joe Johnston, chief concept designer on the original Star Wars trilogy, was also the production designer on this movie. He not only created the overall look of the Ewoks with George Lucas. He also penned a children's book, "The Adventures of Teebo".
