In the Mouth of Madness, The Thing, and Prince of Darkness are all taking place in the same universe.Wait, all three films are referred to as "the apocalypse trilogy"... would that make Sutter Cane, the alien bacteria and the titular prince of darkness three out of the four horsemen?
John Carpenter is Sutter Cane!And Sutter Cane WAS H P Lovecraft! But books did not reach that many people back in the day, and H P Lovecraft's visions and writings were not so well received in the era they were written, so he rewrote himself as a new character and became John Carpenter. Of course films being the new medium to reach the largest audience was all part of the plan, unfortunately, his films were not mainstream enough to be massive blockbusters and reach the maximum number of people possible to cause the apocalypse. Maybe he will become a game developer next...
