But my real agenda is simple: I want to make a more definitive list of the worst movies ever made. When people put this list up, sometimes they'll have well-received ones or movies that are bad in comparison to most movies the average moviegoer sees in theaters. Example: If I stuck with the average popular movie, the worst on my list might be Cats and Dogs 2: The Revenge of Kitty Galore. But I want the absolute ****tiest pieces of work imaginable. And with Franco already having made the first and third worst I've seen, I see his catalogue as a potential goldmine for entries. Besides, they've helped me a lot with my riffing.
Oh. I would not have guessed that from you choosing Jess Franco. He makes sleezy, euro-trash, low budget movies, but people seek him out because he did weird low-grade artsy stuff while in that genre.
The worst he ever did that I saw was make movies that were boring.
Granted, I also didn't look for eras when the reputation of his movies were... bad.
If by bad movies, you want inept movies which is how I'm reading 'bad' here, which might be different than what you want.
The standard movies on these types of lists currently are (I believe): Troll 2, The Room, Birdemic, and The Miami Connection.
Assuming you want stuff more off the beaten path (I haven't seen Crumbs' list as I'm writing this, but I'm sure there's about to be a lot of overlap):
Director-wise, check out Andy Milligan.
I think Andy Milligan's Dracula was entertaining, Monstrosity was not.
He has a lot of movies. Not all of them are inept, but anything horror seemed to be (there's... a lot. e.g. The Ghastly Ones).
from the list that me and Crumbs will probably pull from:
Things, Boardinghouse, Nightmare Weekend (this one even I couldn't enjoy), Ogroff: The Mad Mutilator.
Claudio Fragasso did movies besides Troll 2. Rats: Night of Terror is a hoot. Monster Dogg (starring Alice Cooper!), has some dialogue and a music video, is less so.
One I've heard about for years is Sledgehammer. Still haven't seen it. But it's on Shudder. Will this be the October I watch it.
I guess for stupid more than funny, you could also check out Kiss Meets the Phantom of the Park that plays like a Hannah Barbara cartoon (different than the European theatrical release, known as Kiss and the Attack of the Phantoms).
I'd suggest Rock 'n Roll Nightmare, but Rifftrax did an episode on it at some point.
Not the worst ever made, but interesting oddities (which is how I view the appeal of a lot of bad movies): Raw Force (aka Kung Fu Cannibals) and Lady Terminator.
If you want bad, fun, 80's action, try Samurai Cop. Dangerous Men also made the rounds.
It feels like there's a lot I'm drawing a blank on. I might need to get back to you on this.
ETA: Correction, originally spelled Ogroff as Orloff.
