There might be even more lore about the Star Wars Holiday Special than about the Star Wars universe itself. Aired once in November 1978 on CBS and then locked away beyond the reach of legitimate viewing, it sends Chewbacca back to his home planet to visit his family: his wife, Malla; his father, Itchy; and his son, Lumpy. (Yes. Lumpy.)
The special had guest stars like Bea Arthur and Harvey Korman and original cast members from the movie, including Mark Hamill, Carrie Fisher and Harrison Ford. It was a true variety show, complete with singing and dancing. And skits!
