My suggestion yesterday that the "Lankies" were well-suited to stop-motion and a silent film might be taken remiss by some readers. But not every pre-talkie was an over-acted two-reeler in the manner of Perils of Pauline; they became their own art form, as capable of depth and drama as any other. There's at least one modern example, which I have reviewed: The Artist. Call of Cthulhu is another more-or-less recent silent, filmed in period style on a tiny budget but a successful dramatization of the Lovecraft story.
It's a kind of crazy-lost corner of film -- but there are gems there, from Buster Keaton to the elder Fairbanks. And in the theater of my mind, herky-jerky alien beings lurching across a Brutalist urban landscape fit right in.
