Kiera Knightley could be Mrs. Pole. She's skinny enough and could easily be made pale and wan. I think Arabella would be a sturdier sort of woman, but I can't think who. Hmm. Oh! Helena Bonham-Carter! I like her.

You're right about David Bamber, I suppose, but in my head he simply will continue to play Norrell. I love Colin Firth and Crispin Bonham Carter as Lascelles and Drawlight, and then it could be both a P&P and Bonham-Carter reunion. How lovely! Both for us and them.

I do hope everyone else realises about Alan Davies and the absolute necessity that he play Jonathan Strange.
