In my undying quest for really bad B-movies I seem to have come across a gem: the Star Wars Holiday Special.
Apparently, this little beauty was run in 1978 and ONLY 1978. It's so bad George Lucas has reportedly said he wants to take a hammer and destroy all copies existing. This, of course, makes me want to watch it even more!
Just take a look at the link and imagine the carnage...and the nose-soda-spewing you can have if you watch it. I am and counting the days till I get my hands on a copy.
