If you have windows media player, you can check out the trailer for the upcoming screen adaptation of Philip K. Dick's A Scanner Darkly. Be sure to disable your pop-up blocker.
Director Richard Linklater employs the same animation technique that he used in Waking Life. If you haven't see that film, he shot it live-action and layered the animation over the action to evoke a feeling of unreality, a notion that should work well with Dick's reality/unreality theme in this movie. I'm looking forward to the release, scheduled for February 2006.
I'm still waiting for somebody to adapt my favorite Dick novel, Ubik. That's my favorite P.K.D. melon twister of all time.
