Our friends at Colin Firth 24/7 have Part One of the (original) script of Pride and Prejudice written by Andrew Davies. It's a PDF file, 192kb. Unlike the other scripts posted here before, this version includes not only the dialogue but also directions and such.
This is as good a time as any to give shoutouts to other collaborators over the year: Driving Mr Spacey, A Genius At Work, AustenBlog and A Truth Universally Acknowledged - thanks for your help! Thanks also to the good folk at Pemberley and Clever Company for putting up with our pot-banging.
