Have just watched A Scanner Darkly and really enjoyed it but it was a little predictable tbh. Still, I like Phillip K Dick's writing and the two films I've seen - Bladerunner and A Scanner Darkly - have both been good...might have to check and see if any more of his work has made it to the big screen.
