In my Arthurian Legends class the other day, we were discussing some of the various man-out-of-time versions of Arthuriana, mostly of the Connecticut Yankee strain, but also containing a little bit of "some vaguely Arthurian person comes to the present" tradition. In this discussion, I brought up the film Army of Darkness. Interestingly, most of the student had seen it (though they could not have been more than around seven years old when this R-rated film was released) -- but none of them seemed to realize that it is a demonic parody of Twain's Connecticut Yankee in King Arthur's Court.
First of all, I should note that sometimes when we say "demonic parody," we mean it in the figurative sense of following Milton's themes. The genre of a work does not have to be parody, nor does it have to contain characters that are literal demons. In this paper, for example, someone makes the case that Max Max: Beyond Thunderdome is a demonic parody of the present -- even though the film doesn't actually have any demons, and is not what we would normally call "parody." In the case of Paradise Lost, of course, the demons actually set up a reign in Hell that parodies Heaven ... the ur-demonic parody.
Army of Darkness, of course, is both a literal and figurative demonic parody, and then has its own embedded demonic parody as well. Ash is the Yankee, wielding Excalibur (primarily represented by his chainsaw hand, but also sometimes represented by his "boomstick"). Unlike Twain's Yankee, he does not seek to make the lives of those in Arthur's court better. Instead, as the anti-hero, he uses his superior weaponry (and undeserved sense of intellectual superiority) to make his own life easier at the expense of others. Twain's Sandy, Hank the Yankee's beloved, is replaced by Sheila, who quickly learns a bitter lesson about Ash's late-20th-century sense of commitment, when in response to her protestation, "but what about all those wonderful things you told me?" he replies, "That's just pillow talk, baby."
Here it might just be one of the better films in the tradition of Connecticut Yankee parodies, including such notable works of high art as Black Knight, A Spaceman in King Arthur's Court (originally released as Unidentified Flying Oddball, and A Kid in King Arthur's Court. Sam Raimi, though, takes it a step further, folding the parody in on itself. A demon-clone-sorta-thing of Ash abducts Sheila and transforms her into a zombie Deadite (where they actually appear to have a more committed relationship than the non-zombie Ash can manage), set up an alternative Deadite court/army, and attack the living, finally forcing the living to band together against them. The demon-Ash parodies both Ash himself (looking like an undead version of Ash), as well as King Arthur (here divided into "Lord Arthur" and "Duke Henry").
So, why haven't I published a paper on Army of Darkness as medievalism? Probably because the above is about all I have to say on that subject, but also because it is hard to write about something you love. I live my life according to the teachings of a few wise thinkers, and Ash occupies a position in the higher pantheon.
By the way, Bruce Campbell has a new book out, entitled How to Make Love the Bruce Campbell Way. This book will no doubt occupy a position of great honor on my bookshelves.
