Return of the Jedi - Easter Eggs & Hidden Details
Easter Eggs
A tennis shoe and a potato can be seen floating among the debris during the space battle outside the Death Star.
These were inside jokes added by the visual effects artists at Industrial Light & Magic. Ken Ralston, one of the artists, famously included a shoe in the asteroid field in "The Empire Strikes Back" and continued the tradition here as a gag.
During the final confrontation, Darth Vader says to Luke, "Obi-Wan has taught you well."
This line gained a new layer of meaning after the release of "Revenge of the Sith" (2005). It echoes the climactic duel between Obi-Wan and Anakin on Mustafar, where Obi-Wan gained the high ground. Vader's line in "Jedi" can be interpreted as a bitter acknowledgment of Obi-Wan's skill, which led to his own defeat and dismemberment.
Director Richard Marquand has a cameo in the film.
He appears as an AT-ST driver on Endor. He can be seen briefly when Chewbacca and a pair of Ewoks hijack the walker.
The languages spoken by several aliens are based on real-world indigenous languages.
Jabba the Hutt's language, Huttese, was based on Quechua. The Ewoks' language was inspired by Tibetan and Kalmyk Oirat, and Lando's co-pilot Nien Nunb speaks a Kenyan dialect called Kikuyu.
