Ewoks originate from the Star Wars films. In the series, they are a species of teddy-bear-like hunter-gatherers that inhabit the forest moon of Endor. The Ewoks live in various tree-huts and primitive dwellings. They first appeared in the film Star Wars Episode VI: Return of the Jedi (1983). They have since featured in two made-for-television films, Caravan of Courage: An Ewok Adventure and Ewoks: The Battle for Endor, as well as an animated series and several books and games. Some fans of Star Wars say that Ewoks are silly and "ruined" the film.^[1]

George Lucas created the Ewoks because he wanted Return of the Jedi to feature a tribe of some primitive creatures that bring down the technological Empire. He had originally intended the scenes to be set on the Wookiee home planet, but as the film series evolved, the Wookiees became technologically skilled. Lucas designed a new species instead, and says his approach was simple: Wookiees are tall, so he made Ewoks short.^[2] The Ewok are named after the Miwok, a Native American tribe, indigenous to the Redwood forest in which the Endor scenes were filmed for Return of the Jedi, near the San Rafael location of Lucas' Skywalker Ranch. The name also is a pun on the syllables of Wookie in reverse order. ^[3] In the film, the name "Ewok" is never actually pronounced, but appears in the ending credits.

As presented in the films, Ewoks appear as stocky, sapient bipeds which stand about one meter tall. They have flat faces, are completely covered in fur, and have large jewel-like eyes. Both their fur and their eyes come in a variety of earth-tones, primarily brown, white, grey, gold, and black. Despite their small size, Ewoks are strong; in the climactic battle scene of Return of the Jedi, they are shown physically overpowering and once even throwing Imperial Stormtroopers, though this detail is not consistent throughout the film. Ewoks live high among the trees of their home moon's forests, in villages built on platforms between the closely spaced trees.

An "Ewokese" language was created for the films by Return of the Jedi’s sound designer Ben Burtt.^[4] On the commentary track for the DVD of Return of the Jedi, Burtt explains that the language is based on Kalmyk, a language spoken by the Kalmyk people of Russia. Burtt heard the language in a documentary and liked its sound, which seems very alien to Western ears. After some research, he identified an 80-year old Kalmyk refugee. Burtt recorded her telling folk stories in her native language, and then used the recordings as a basis for sounds that became the Ewok language and were performed by voice actors who imitated the old woman's voice in different styles. For the scene in which C-3PO speaks Ewokese, actor Anthony Daniels worked with Burtt and invented words, based on the Kalmyk recordings.^[5]
