Boba Fett & the Star Wars Holiday Special
A cartoon is appropriate for a Saturday morning, right? I thought so too.
If you've ever seen the "Star Wars Holiday Special" from 1978, you'll probably remember it's shockingly bad. I think this review at I-Mockery sums it up. However, one watchable segment of that awful mess is a cartoon starring everyone's favorite bounty hunter (hush up, Bossk and IG-88 fans) in his first on-screen appearance. This 10-minute bit of animation features Boba Fett and a number of other famous Star Wars characters. The style is very similar to the old Droids cartoons that aired back in the mid-1980s.
Someone with an odd sense of humor (bravo!) has also created a website dedicated solely to the "Star Wars Holiday Special". I guess that was a niche just begging to be filled, eh? There is also, as you might expect, an extensive Wikipedia entry on the special.
I'm not aware of any way to get an official copy of the holiday special itself, apparently because George Lucas doesn't want it circulating. However, if you use bit torrent....
