Development
During the 1970s, when George Lucas envisioned the whole story of the Star Wars saga with four trilogies and twelve episodes, he conceived a Wookiee-centric film along an untitled film about droids. The film was supposed to have the Wookiees as the main protagonists. After the enormous success of Star Wars: Episode IV A New Hope, in 1977, Lucas decided to release the Wookiee film in 1980.

However, at the end, Lucas opted for continue the original trilogy and decided to work on Star Wars: Episode V The Empire Strikes Back and released it in 1980 instead that the Wookiee-centric film, leading it to its cancellation along the Droids film.

Despite this, many concepts of the planned film were later used and adapted into The Star Wars Holiday Special and in the 1985's animated TV show Star Wars: Ewoks.
