I also started watching the BBC's 1985 adaptation of Charles Dickens' Bleak House last night, an eight part series of one hour episodes with Diana Rigg as Lady Dedlock, Peter Vaughan as Tulkinghorn, and Denholm Elliot as John Jarndyce. Mostly I like it so far. I love the literally bleak quality of it, all the darkness with murky lanterns or candles feebly illuminating faces.
The casting is the best part, though, except for the overly slimy guy they have playing Guppy. Peter Vaughan, too, might come off as a bit too sanguine for Tulkinghorn but Diana Rigg as Dedlock seems perfect. However, the casting of Denholm Elliot as John Jarndyce cannot be rivalled in its perfection. Few actors would more perfectly and genuinely convey the combination of generosity, modesty, and deep, barely repressed sorrowful frustration.
