Trippy visuals aside, there's a lot in this trailer that didn't make it to the final film.
Phase IV is a movie that someone told me about years ago, when he was on an ant interest-binge. The plot he gave me was nothing like what I actually saw, so I assumed that either it had been a long time since he'd seen it, or he thought I never would.
Years later, I used to listen to the insane "Cultural Pollution" mixes on ISRN.ORG (now defunct), and one involved a lot of the music from Phase IV. I didn't know it at the time, but I did enjoy it. It wasn't until I was on my own interest-binge—Saul Bass—that I discovered this very, very strange movie.
I'm also very sad that Mr. Bass, a gifted visual artist, did not get to do the poster for his own film. Something about that seems very, very wrong.
The jury's still out if it's a good film with really bad parts, or a bad flick with really good parts. Let's take a look at it.
