Wow, thanks for the link to the Daisy Chainsaw video! It's great, and I love how they have taken advantage of the visual medium to echo Nosferatu's grainy, high-contrast black and white look, as well as very much capturing the Great Expectations vibe.

Thanks also re the info on The Duchess of Malfi. I've never seen or read it, I'm afraid, but a skim of the Wikipedia page supports what you say.
