Question: Which  "Star Wars" spin-off of 1978, directed by Steve Binder, did Wookiee Planet C make appearances in?
Sentence (from "Kashyyyk"): However, Lucas decided that since the Wookiee Chewbacca was clearly proficient with advanced technology (i.e. he was pilot and mechanic of the spaceship the "Millennium Falcon" and he repaired the damaged droid C-3PO), it would be confusing to show the Wookiees with a primitive, "stone age" culture on Endor.
Relevant evidence: No
