Chewbacca is a character in the Star Wars franchise. He first appeared in Star Wars Episode IV: A New Hope in 1977. Chewbacca, a Wookiee, became Han Solo’s first mate and companion after Solo, then an Imperial Captain, refused an order to kill him while Chewbacca was a slave of the Empire.
Note: The Chewbacca defense is an amusing legal strategy from South Park that satirized attorney Johnnie Cochran’s defense of O.J. Simpson in his murder trial. In essence, “if Chewbacca lives on Endor, you must acquit.” Look at the silly monkey!
