Beyond being a historian of exploitation films, Frank Henenlotter has made some outright insane movies like Frankenhooker and Basket Case. What other kind of mad genius would hire horror host Zacherle to be a worm named Aylmer, who creates drug-like relationships with his hosts while demanding to eat the brains of everyone they love?

That blue phallic worm secretes a highly addictive hallucinogen directly into the brain, forcing Brian to leave behind his life, his girlfriend and any hope of normalcy, all while being pursued by the old couple that had imprisoned the parasite and who know way too much of his history, leading to some of the longest and most hilarious expository dialogue I’ve seen in a film.

During the fellatio scene — yes, a woman puts Aylmer inside her mouth — the crew walked out, refusing to work on the scene.

There’s a great moment where Duane and Belail from Basket Case meet Brian on a train before he ends up killing his girlfriend. I realize that’s a spoiler, but nothing can prepare you for this movie. It’s truly one of a kind.

You can watch this on Tubi or on Shudder with and without commentary by Joe Bob Briggs.
