Recycling: Jane Austen edition

Oooh, forum posters at the Republic of Pemberley have dug up several photos of the upcoming film adaptation of Jane Austen's Emma.

I don't understand why they cast Johnny Lee Miller as Mr. Knightley. Couldn't they have found somebody who hadn't already played an Austen hero? I hated Mansfield Park, but I actually thought he was pretty good as Edmund Bertram. But as Mr. Knightley?

No. A thousand times no.
