In our last post, I discussed the various literary influences apparent in In the Mouth of Madness. Today, I’m delving a bit deeper into some of the tropes and philosophies that informed Lovecraft’s work, and this film in turn.
In the Mouth of Madness opens with John Trent being admitted to an insane asylum, where he recounts his story to an investigator (David Warren). One of the most common tropes in Lovecraft’s work is the notion that some truths are so terrible as to cause the knower to go insane. Consider this noteworthy opening quote from “The Call of Cthulhu”: “The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.” In some Lovecraft stories, acquiring forbidden knowledge not only causes insanity, but forces bodily mutations upon the victim. This is apparently a trope within Sutter Cane’s fiction and also happens to unfortunate readers of his newest novel, In the Mouth of Madness. In some respects, these mutations are reminiscent of transformation scenes in John Carpenter’s earlier film The Thing.

Misanthropy was rampant in Lovecraft’s fiction. In a letter to Edwin Baird, editor of Weird Tales, Lovecraft wrote of a young writer who wished to pen a story of a mad scientist who strives to conquer the world by unleashing a plague. To Lovecraft, this vision unoriginal and simply did not go far enough. “Good and evil, teleological illusion, sugary sentiment, anthropocentric psychology–the usual stock in trade, and all shot through with the eternal and inescapable commonplace…Who ever wrote a story from the point of view that man is a blemish on the cosmos, who ought to be eradicated?…I told my friend, he should conceive of a man with a morbid, frantic, shuddering hatred of the life-principle itself, who wishes to extirpate from the planet every trace of biological organism, animal and vegetable alike, including himself…Only a cynic can create horror–for behind every masterpiece of the sort must reside a demonic force that despises the human race and its illusions, longs to pull them to pieces and mock them” (Quoted in Thomas Ligotti’s The Conspiracy against the Human Race: A Contrivance of Horror) .This attitude is rampant in Sutter Cane’s work, and John Trent offers a similar opinion at one point when he tells Linda Styles, “The sooner we’re off the planter, the better.” However, Trent is ultimately unable to maintain that stance–or perhaps it was mere posturing all along–because he tries desperately to save humanity in the film’s final act.
The last and perhaps most important Lovecraftian trope is identity-based horror. (And here I spoil the best scene in in the movie.) In “Through the Gates of the Silver Key,” Lovecraft writes, “No death, no doom, no anguish can arouse the surpassing despair which flows from a loss of identity.” Savvy viewers would know that John Trent is set up for such a fate, given his arrogance and frequent comments along the lines of “I’m my own man; nobody pulls my strings.” The revelation that he is not his own man and in fact has no free will is expected, but the specific nature of this revelation delivers a gut-punch arguably superior to similar twists penned by Lovecraft himself. In a confrontation with between Trent and Sutter Cane, Cane reveals, “This town didn’t exist before I wrote it, and neither did you…You are what I write!” Trent sputters and protests that he is not, in fact, a “piece of fiction,” Cane responds, “I think, therefore you are.” Trent is not even left with the solace of having once been human. He simply never was what he believed himself to be, and technically, was never real.
I will further discuss the notion human existence as puppet existence in our final post on In the Mouth of Madness and its religious implications, and in my review of Thomas Ligotti’s The Conspiracy Against the Human Race.
