Alright haha, LAST POST. I know I've posted a bunch, but it really got my brain workin haha.
What about some Grindhouse/Explotation flix - ala Love Camp 7, Llsa She Wolf of The SS, Cannibal Ferox/Holocaust,
and almost any Giallo or Spaghetti Western film would work. I'd love to see them riff on Somethin by the directors Joe Dante, Dario Argento (Deep Red, Suspira, Inferno), Mario & Lamberto Bava or Lucio Fulci (Don't Torture A Duckling, The Beyond, A Lizard in Womens Skin, A Cat In The Brain)
The Plethora of Don't Open The.... Don't Go In The.... Don't Answer The.... Last House on The .... (excluding Left, as the ones I'm talking about are trying to cash in on carpenters success). Hell - Sleepaway Camp would be funny as hell too.
LOL - Escape from New York, while on the topic of John Carpenter.
NIGHT OF THE DEMONS from 1988 would be a great one. The old one, not the remake, with Angela. Witchboard is another campy one from the same writer.
Attack of the Killer Tomatos could be cool, if done right. Or The Blob (original or remake).
and I kinda wanna puke in my mouth thinking of this series again, but it would a great rifftrax, the "House" series - like 1 through 5 or whatever.
