H.W.
I have a copy of the Jennifer Ehle/Colin Firth version of Pride and Prejudice which I adore ardently and watch every so often. I really don't ever get tired of it. This is the version which is most faithful to the book, which runs some 360 pages or so, and chronicles the finer details which Austen renders so skillfully-- the dinner and chamber conversations are especially laden with satire and yes, I could go on...
I also enjoy the 1940 offering with Greer Garson and Sir Laurence Olivier, although I think his Darcy is far less yummy. They still maintain the wit inherent to the intention of the satire. As for the Kiera Knightly version... boy, I really wanted to like it, but the end of it just killed me. Freaking (!!!)fireworks(!!!) over Pemberley as they kissed? Egad. I just keep thinking that the "real" Mr. Darcy would have found something like that quite vulgar. Did they not get who that character was? Cute movie for teen girls, but really NOT for the purist.
Doris: I saw Harriet Walter recently-- Lark Rise to Candleford, I think. I have that one too, BTW. :)
