The novel of LEGION is littered throughout with references to Dostoevsky's THE BROTHERS KARAMAZOV, which I think speaks to Blatty's take on theology which appeals to us both.

And as for Dourif, man, when I saw the first trailer for THE DARK KNIGHT, I was thinking, "Holy fuck, he's channeling Dourif as the Gemini Killer!"

As for Henchgirl, don't worry! It's not like that at all, and I apologize if I've led you to believe that was the case. I believe she's composing her own response!
