A Scanner Darkly

I know I'm setting myself up for disappointment, especially after the horror of Waking Life, but my excitement levels are building for A Scanner Darkly. Linklater is capable of making fantastic films where nothing happens but which capture a mood or the tone of a time and place - Suburbia, Dazed and Confused - so ... I'll stay hopeful. Not sure how closely it sticks to the book - I read the Charlie Kaufman script a few years ago and it stuck surprisingly closely to the book, but on IMDB the script is credited solely to Richard Linklater.

I am a huge huge fan of Philip K Dick, and A Scanner Darkly is my favourite of his novels, so a well-made film of the book would be awesome.
