tinyE: Not to jack the thread but I'd like your take on the other adaptations. I'd like everyone's take on them. I know some folks feel if you take libertys with the story for the sake of the screen then it doesn't matter if it's good or not, it's still heresy. I for one do not fall into that catagory, but I'd love to hear some other opinions.
Actually, with the exception of "A Scanner Darkly", I would be reluctant to call the movies that were based on Dick's works "adaptations". They are certainly inspired by Dick's stories, and used some of his characters and ideas, but they changed so much that the source material is barely recognizable. That doesn't mean they are necessarily bad movies - it just means that there is much less Dick inside them than people tend to think.
Dick was wildly imaginative and deeply disturbed, and he also managed to stand with one leg in the depths of pulp, and with the other in serious intellectual, philosophical, and partly religious research. The movie adaptations of his stories focus on the imagination and the pulp aspects, and show only a glimpse of Dick's other characteristics. hey are good entertainment (mostly), but they don't compare in any way to the reality-shattering experience that reading one of his novels can be. On one hand, that's a pity, because there are now millions of people who _think_ they know Dick because they've seen the movies, but in reality they've only experienced a watered-down version of him. On the other hand, Hollywood may have bee right, and the watered-down version of Dick is probably much more mass-digestible than the real thing.
One thing to note is that Dick may have been discovered a bit too early for movie adaptations. In the 80s, the concept of having different levels of reality in a mass-produced movie was still very risky. Heck, even foregoing the obligatory happy end was considered risky (see the theatrical cut of Bladerunner, and Schwarzenegger's Total Recall). In the meantime, we've had movies like Matrix and Inception, we have a whole popular subculture of conspiracy theories, and the idea of a reality behind the reality, and perhaps another reality behind that, is now much more digestible than it was 30 years ago.
I'm kind of hopeful that the time might be right to show the world the "real" Philip K. Dick. There are ongoing negotiations about a "Ubik" movie (imho his best book), and depending on how that's done, it could be really good. If the audience could handle Inception, then it can handle a version of Ubik that's not massively watered down.
