Esper-what? Succu-who? Let’s start with what we DO understand: awesome. William Shatner is awesome. He’s even more so when he’s the star of “Incubus,” a 1960′s horror film about soul-stealing blondes and satanic rituals…spoken in the wholly invented language, Esperanto. You’ll have to look up “succubi” on Wikipedia. We’re not here to teach you English… or Esperanto for that matter.
