Twice Upon a Time (1983) film
This is a lost stop-motion animation film that was produced by George Lucas.
This should definitely get riffed!

This was posted somewhere else, but I voted for both. 'George Lucas' is enough for me!

I haven't seen this since it came on HBO back in the 80s. Please do this,if only for the fact it's impossible to find

You had me at George Lucas. Besides we all know how his other "lost " gem turned out.
It was found ans is now the stuff of Rifftrax legend... The Star Wars Holiday Special
