But enough of that.
Here’s the trailer if you haven’t seen it:
Soldier, statesman, and alchemist—which latter was the highest development of the science-knowledge of his time. He had a mighty brain, a learning beyond compare, and a heart that knew no fear and no remorse. He dared even to attend the Scholomance, and there was no branch of knowledge of his time that he did not essay. (Ch. XXIII)
Into the lands of civilisation came Nyarlathotep, swarthy, slender, and sinister, always buying strange instruments of glass and metal and combining them into instruments yet stranger. He spoke much of the sciences of electricity and psychology and gave exhibitions of power which sent his spectators away speechless, yet which swelled his fame to exceeding magnitude. Men advised one another to see Nyarlathotep, and shuddered. And where Nyarlathotep went, rest vanished, for the small hours were rent with the screams of nightmare. (“Nyarlathotep,” 1920)
In raw terms, it’s easier to sell a big name like Dracula over “the soul and messenger of infinity’s Other Gods,” especially since the show is an international co-production and has to be able to appeal easily to people who don’t speak English. And of course he has to pretend to be American or U.S. audiences won’t watch the show, at least according to network executives. (So ingrained is this belief that even BBC America insists on having American-accented characters in all its original programs.)
