Fair warning, I saw this film break a veteran attendee at B-Fest last year. It is about infinity minutes long and there isn't much to work with along the way. Also I am pretty sure I accidentally killed George Burns by renting it at a Blockbuster in the '90s. I woke up the next morning and he had passed in the night.
This needs to be a thing! There was a nifty DVD a few years ago featuring the traveling Spook Show film "Monsters Crash the Pajama Party" (itself only about half an hour long and originally staged as noted above with "real" monsters in the theater) that featured a lot of this sort of stuff alongside the main picture. That would be the perfect model for this sort of show!
It probably would help them if you spelled it correctly, it's "Xanadu".
But it is an outstanding suggestion.
You know how everyone has that one batshit insane bad movie that they inflict on all their (possibly soon to be ex-) best friends. This one is mine. Simmons' band of preapocalyptic (not a typo) goons really help sell the insanity. And you actually realize how good Robert Englund is watching him steal every scene with his mugging in the background. And this while playing beside Gene at his utmost ham and cheeziest!
"No, not the finger!!!"
