I found this the other day. It's called the Star Wars Holiday Special, and it came out in 1978, not long after the first Star Wars came out. According to this Wikipedia article, it was known for being really bad. I tried to watch it, and friend - I barely got a third of the way. I just couldn't sit there and let brain cells die. What was George Lucas thinking?
And to think that this special had all the main cast members from the movie in it. I think they did it only because they were still new in Hollywood, and if they didn't do it, they probably were told they wouldn't work in that town again. Luckily, their careers didn't suffer from being in this special, because they went on to make two other Star Wars movies. Word of warning, friends: In addition to killing brain cells, it might also cause sterility.
By the way folks, this is my 50th blog entry! Yay me!
