There are really many hilarious happenings in this film, as well as pretty good creations. The costumes mainly hold my attention. They are numerous and very complete with details. They obviously hold an important place in Gwar’s art (at least as much as music in my opinion).
You never see the band members’ faces, and you never will… Further than Kiss, Alice Cooper (always wearing make-up) or Gorillaz (previously famous people who made up a band where they only showed cartoon characters looking like them), Gwar have never shown their real faces in public (even though I think you can see their faces in the film, while they sit in the court). They always wear the masks of the Neolithic characters of their epic.

“Classical” styles and people often inspire their music and art, usually quite in an ironic way but not in a degrading one.
In the film, they start a song as a jazz/blues band. Of course, they did not lose their masks. It makes it a strange looking jazz band. But after all, the music is nice to listen to (as jazz or blues always is…) and it is very entertaining to look at these monsters singing something nice and behaving classy and jazzy.

There is so much derision and vulgarity but also aesthetic, cultural references and precision in their work that it can be considered an end in itself. And they are very good at that work.
The cultural references are multiple, in style and in the texts and names.

As said before, the costumes are very well crafted, they created a whole world of themselves with many heroes with powers and diverse attributes.
Among them, the famous penis (which was supposedly cut off from the band’s singer) that maintains to be a fish in the film. He is sued for obscenity. He is proved to be a penis and his arrest is ordered.

Behind the funny face of the artwork is an underlying thread about liberty of speech and censorship. In the film, the government, the clergy and the health care communities have censored Gwar. The “morality squad” has kidnapped one of the members of the band, the cuttlefish of cthulu, and they put him on trial for obscenity.
Gwar did indeed have trouble with censorship and conservative organizations with their previous works. They actually had to stop their UK tour for the album “America must be destroyed” because of conservative movements. The film depicts their problems in a scorn way. When they were on trial, the band argued the penis was actually a fish.
In a way, the film depicted reality before it happened. Marilyn Manson used the same technique later on. They predict what their opponents will do about this work. When the opponents actually do it, the band can claim to be right.

From the start, before they encountered problems, Gwar fought against censorship. They created a world of violence, sex, and horror.
They were criticised and even sued because of the sexual obscenity of their pictures. That’s why they had done it. But the most shocking should be the horror, not the sex. Gwar want to make it clear that the American society (this can be extended to most other societies, but Gwar is an American band) accepts unacceptable violence but not sexual matters, which originally are a natural thing.

There is more to say about Gwar. But as a conclusion I’ll say that Gwar not only provokes to deliver their political message, they make it in an artistic and aesthetic way. Both are worth watching the film.
