My wife automatically knows to just leave the room when Bloodsport comes on. No way I’m not watching it. I don’t even need the DVD, since it’s on about ten times a year.
Beastmaster is another “always-on-TV” one that I love. “We must fight!! No!!! We must flee!!!”
But nothing baffles her more than during the holidays when my four brothers and I sit down and watch Strange Brew. Doug Moranis and Dave Thomas as the “MacKenzie Brothers.” Max Von Sydow as the evil Brewmeister with plans for World domination achieved through drugged beer. I tell ya, we know every line, and we love it.
Doug Moranis??!! I meant Rick Moranis. I’m a hoser.
A barely notice film starring John Ritter and Anne Archer (and featuring Burt Convy): Hero at Large
I bet I’m the only person on Earth (including the cast) that remembers it. But I’d love to see it again.
Another vote for Brain Dead here. My favourite quote: “They’re not dead exactly, they’re just sort of… rotting”.
Also I’m suprised no-one has mentioned the classic Commando!
The Perils of Gwendoline. I love this movie. Its irredeemably stupid, but it does have a lost city of topless amazons, and Tawny Kitaen naked, and a 30s-serial pastiche plot. Lots of nudity.
Saltire, you lose. 
I remember going to see it when I was in the third grade. Didn’t seem so bad at the time, but then, I was in the third grade.
Hey, I like the monster in The Best of Yucca Flats :).
A few way cheesy favorites - Attack of the Killer Shrews ( oh no! German Shepards with carpeting hung on them! ), Attack of the Mushroom People ( Mushroom people! how can you go wrong with that? ), and Vamp with Grace Jones ( three words - “Albino Street Gang” 
).
On the other hand I’d have to say that Legomancer is clearly insane 
- I’d rather be crushed under a landslide than sit through Dungeons and Dragons again. It was almost physically painfull ( stepinfetchit-like sidekick dies - “Nooooooo!!!” ) :D.
- Tamerlane
Tremors
D&D
Death Race 2000.
(A few of the movies already listed are on my favourite movie list, but I don’t think they’re bad, but I won’t mention them.)
Tengu - Well IMHO Tremors isn’t a bad movie either ;). Now Death Race 2000 is, but I love it anyway ( I have a weird thing for Roberta Collins aka Mathilda the Hun ).
- Tamerlane
I love having a bad movie night every once in a while. Usually tops on my list is The Seventh Voyage Of Sinbad, or any of the Sinbad movies. I also love Clash Of The Titans. I think it’s a mix of testosterone, poor claymation, and overall hokey sound effects that I love.
I also will watch Enemy Mine any time it comes on television, I’m pretty sure I could sit through it a few times in a row. For some reason, I just never get tired of this movie.
I’ve been told several times Time Bandits is horrible, but I own the dvd. I still laugh in all the same spots and by the time the Robin Hood segment rolls around, I’m rolling with gales of laughter. 
WHAT!!!
Take that back!
Bad Claymation??? These movies are the best work of animation legend Ray Harryhausen. 7VoS was my childhood favorite, and still one of the best fantasy films ever made. Gotta love Torin Thatcher’s villain, and that wonderful Bernard Herrmann score.
And no clay involved – Harryhausen’s models were foam rubber compositions over articulated metal armatures. “Claymation” was a term invented by Will Vinton for his work with plasticene (usually over metal armatures, too, BTW).
And Altered States is, I regret to say, an artsy, over-the-top Bad Film. Maybe if they stuck with Paddy Chayevsky’s original script, or the original director, it could’ve been good. Going with a flamboyant director in mid-stream was a recipe for an incomprehensible flick. Even Dick Smith’s makeup effects couldn’t save it.
But I love the all-too-0brief shot of a nude Blair Brown. And I think the shot of a rhino in the supposedly “Boston” zoo is a giggle. AFAIK, there’s never been a rhino in any Boston zoo. And none of the “Boston” scenes were shot there (even the outdoor ones).
Gotta agree with Eve about Queen of Outer Space. A Spectacularly bad film with bad science, using recycled costumes from Forbidden Planet. What kills me is that Charles Beaumont wrote the screenplay. Beaumont was a gifted short story writer for the horror and SF pulps, and would go on to write several of the best original Twilight Zone episodes, as well as other movie scripts, including The Seven Faces of Dr. Lao. How he pumped out this bit of sludge I cannot imagine. H must’ve done it with tongue in cheek. And, what the hell, it was his first movie script.
I’ve heard it said that the script for Queen of Outer Space was intentionally tongue-in-cheek, but nobody involved with the production realised this. Of course, that could just be an excuse… (I think this story comes from the films section in Kim Newman and Neil Gaiman’s Ghastly Beyond Belief, but I don’t have my copy handy to check.)
My favourite Bad Film has to be Lifeforce. Gratuitous nudity (best kind!)… Steve Railsback’s slack-jawed performance… Patrick Stewart demeaning himself… best of all, it’s just so much better than the original book. (Colin Wilson’s The Space Vampires, just so you know what to avoid.)
I’m surprised no one has mentioned the Airplanes! and Naked Gun flix yet. Intentionally bad to begin with, and OJ as Nordberg couldn’t be any worse. I also want to nominate The Ten Commandments in the unintentionally bad category. Horribly overacted (John Derek as Joshua was horrid), cheesy costumes, and lame special effects make this winner a loser. So what if it won Oscars?
Airplane and the Naked Gun movies don’t count. They were MENT to be bad.
I love Clash of the Titans. Great stuff. Used to love it every time it came on TV when I was a kid. The owl was the best part.
The Specialist a bad movie? I guess. Never thought about it. Great cast though. Gary Oldman is sinister as always.
Airplane! and The Naked Guns aren’t intentionally bad movies: they’re good parodies of bad movies (and bad TV shows.) Big, big difference.
And let’s not forget Top Secret! from the same guys. Where else are you going to see guys on sufboards shooting skeet?
Pink Flamingos.
I was asked out on a date once because I knew the owl’s name was Bubo. Now that’s practical knowledge.

I wish they all could be double-barreled guns . . .
Baseketball.
Almost universally panned, but I can’t resist it.
And then there’s the 1972 made-for-TV movie Gargoyles. Scary bad.
