Plan 9 from Outer Space is a very special bad film.
I especially love how Bella Lugosi got the top billing…and he didn’t have a scene in the film, merely appearing on the TV screen in the film.

Oh man, Barbarella...that's a blast from the past. I watched that one when I was around 12-13...yeah, I really liked it back then...wink, wink, nudge, nudge, say no more, say no more...

Here's one that was very ambitious, but didn't quite delivered in the end (Zardoz, 1974):

I watched it several times as a kid, haven't seen it in a long time so maybe my opinion would change if I did.

I don't think that's quite true. I believe it was that his few scenes were ones filmed previously for a completely different movie (that was never made?)

And then rest of the film the character is played by someone else.

Reminds me of the Rocky Horror Picture Show.

So bad it created a cult following with play script for playing along with the movie in the cinema. It got special viewings for audience performances. Interactive cinema lol.

It was fun to visit one of those viewings in the 90s, although it wasn't a very busy one, mostly our fraternity visiting lol.

I was part of an art house fraternity in University and they had lots of these bad movie great fun, movie nights. Also lots of great art house movies. It introduced me to Quentin Tarantino, Stanley Kubrick and David Lynch.

And yep Plan 9 was one of them. Fun movie!

I was wondering if this one was going to come up. I was actually thinking about using it as the prime example for a thread about “soundtracks that are better than the movies they were made for.”

it definitely has the exact right amount of cheese, action, and heart. I was a huge Def Leppard fan and was stoked that a song would appear in the film when it came out. Unfortunately it’s just the closing credits song, but it was still awesome. 

It would have to be The Room, no?
The writing is bad, the acting is bad, the directing is bad, and so on. But it's so funny to watch the incompetence and not boring or a bad time on the whole because of how bizarre it is.

I'm a huge Godzilla/kaiju fan and I'd say most of the genre falls into this category if I'm honest.

There are some that are genuinely great movies like the original 1954 Gojira or Minus One, but I'd never try to claim that films like Godzilla vs Mechagodzilla are quality cinema, even if they are fun as hell.

Oh, good one. I actually was excited for it back then, only to realize that the trailer made for the movie had *all* the good jokes the movie contained. Watching the trailer was sufficient to enjoy it!

aWW I really like this movie.  It falls in the same category as Fifth Element for me, both fun, but cut from a different cloth than Killer Clowns or Attack of the Killer Tomatoes.
