Das Serum des Grauens

This movie reminds me of The Toxic Avenger and Doom Asylum! It's a hilarious horror comedy that's not meant to be taken hilariously. If you appreciate good bad movies then this is the movie for you!

Well, this is a bad movie but it's pretty fun to watch. A sex maniac professor makes a serum that enables him to be invisible. From this you should be able to know the rest of the story. There are girls chasing, screaming girls, beaten up boyfriends, and high school naughtiness. It's fun.

Why is it that insane, sexually-repressed geeks are the only people who seem to learn the secret of invisibility? A nerdy scientist goes mad and kills some of his colleagues. Why? Cause they laughed at him and his failed invisibility experiment. He soon escapes from an asylum and gets hired as a high school physics teacher. He's teased by several vixens in one of his classes. This inspires him to perfect his formula. Despite being injected into his bloodstream, the serum affects his clothes and eyeglasses (how convenient). Once invisible however, all he can think of is to hang out inside the girls' locker room. After his secret is discovered he goes on another senseless killing spree.

If 700 monkeys were pecking away on 700 computer keyboards for 700 years, one of them might come up with Shakespeare's "Hamlet." It would only take about five days however, for a dozen of them to come up with "The Invisible Maniac." This movie is unimaginably silly and stupid with gratuitous nudity its only redeeming feature. By comparison, it makes other invisible man schlock like "The Amazing Transparent Man" seem worthy of a best picture nomination at the Academy Awards. Then again, you know you're in trouble when the theme song playing during the closing credits is the best thing about the movie.

Released in 1990 apparently straight to video, this film is described as a comedy or even a slasher horror type. Hard to be taken serious given the premise and subpar acting.

The lead character of the teacher/scientist (Invisible maniac) over acts especially with his fake evil laugh. The acting by the students are noticeably bad as most of them weren't exactly veteran actors by that point.

There is very little humor or clever witty jokes. The comedy comes from seeing the teacher spying on the students or some of the awkward interactions and overly sexual acts by the women (students and the one teacher). As noted this film contains a lot of skin throughout as a way to purposefully distract audiences into further enjoying the film. The writing is weak, the directing isn't great but its cheesy and silly tone with its gratuitous nudity makes the film worthwhile enough.

Second half of the film includes more of a slasher element where we see kills by the teacher taking down each student one by one. Some kills were clever and intriguing, although cheesy. The film never fully gets too horror but contains some elements. Overall not a great film but enjoyable for it's purpose.

This film is fundamentally dumb, there is no getting around it.

There are a few highlights, like when some guy gets punched in the face by the invisible dude, its pretty funny.

This film is full of bad actors, not the naughty country kind or spies, just regular bad actors. Like next level bad.

The movie has more shower scenes than a Rheem commercial and praise be to God because they are all the best bits.

It borrows from lots of movies and none of those are any good either.

The movie does provide a few giggles and a couple of wtf moments but don't expect to find any thing more than that :)
