1995 version. That being said, when I saw the 2005 adaptation I was blown away by the filming of the scenery. In particular the footage of Chatsworth House, a.k.a. Pemberley, a.k.a. the house on the plate, is gorgeous!
There he is: the notorious Mr. Darcy in the marble.
Then, later, we see Lizzy flee out the side of the imposing stone mansion...
Followed, of course, by the tension-filled yet romantic conversation overlooking the stunning gardens. Such breathtaking filmography!
