Supposedly Dick's experience conceived three published novels--Valis, The Transmigration of Timothy Archer, and Divine invasion. There is a fourth, unpublished novel--Radio Free Albemuth that came from it as well. Valis seem to be the most personal since it someone named Philip Dick (or Horselover Fat) having the exact same experience then trying to make sense of it. Divine Invasion has more of the feel of a traditional Dick novel with someone forced to live in a hovel on an alien planet. Timothy Archer is borderline non-SciFi, with only a tiny influence of SciFi, IIRC. And Radio Free Albemuth felt a bit like a cross between Scanner Darkly and Valis--i.e. the Valis story in a dystopian future surveilance state.
It's watchable, but my experience is soured by the terrible experience of contributing to the KickStarter and then not being able to get my reward for years due to living in the UK rather than the US (licensing issues).
That said, if you are interested in reading more by him, of his books I can recommend:
- The Three Stigmata of Palmer Eldritch
- Martian Time-Slip
- Galactic Pot Healer
- Eye in the Sky
- the middle part of Lies, Inc
Some of his short stories:
- Beyond Lies the Wub
- Faith of Our Fathers
I think, in 2022, people will understand Scanner better than they used to or maybe it is on the verge of being outdated?
