George Eliot: dialogue master

Is there a movie or TV version of George Eliot's "Middlemarch"? Probably, knowing the British obsession with classic British fiction, there is a version - though it seems far more cerebral than the Dickens or Austen works that adapt so well to screen, large or small. I'm not sure how well the first book, Dorothea Brooke, of the novel would play: what makes it is largely the wise authorial stance of the author and the opposition of ideas as played out in character (or caricature): Dorothea wanting to do good, but weirdly entirely subjecting herself to the will of a much older man who seems to share none of her passion for social justice - and the incomprehension and puzzlement of others in the small village of Middlemarch who puzzle at this liaison. That said, the 2nd book, Old and Young, seems considerably more cinematic, and I'm particularly struck by the great, sharp dialogue: the young man Fred, son of the town mayor-elect, sucking up to the wealthy relative whom he hopes will bequeath him property, and Fred's courtship of his sister's much more plain but much sharper best friend: their dialogue cracks with sharp attacks like Beatrice and Benedict. Eliot's facility with dialogue surprised me, and there was little hint of it in part 1; I wonder the extent to which her talents were sharpened as she proceeded through this project: surely, I think, she would have made Casaubon less of an obvious mismatch for Dorothea is he had a do-over.
