You probably already knew this, but Blade Runner was an adaptation of Phillip Dick's Do Androids Dream of Electric Sheep? Total Recall was adapted from his short story We Can Remember It For You Wholesale, and Minority Report was from, uh, Minority Report.

IMHO, Dick was one of the best Sci-Fi writers. His strength was in addressing the issues that happen when technology becomes so realistic it displaces reality in our every day lives.

Indeed, I am familiar with Dick’s work. He had some serious personal problems, but his writing was usually good and had originality.

Dick was great. But I also enjoy Jack Vance and A.E Van Voigt.

Philip K. Dick, the best description of his work was “achieved a level of paranoia in the 60’s that most of us are only beginning to appreciate today.”

That could work with John Brunner too.

"Dick was one of the best"

Absolutely. I have no idea if it's true but I've read he's had more books made into movies than any other writer except for Stephen King.

To add to your list: Imposter, A Scanner Darkly, Screamer, Next and Paycheck as well as The Owl in Daylight and Radio Free Albemuth which have not yet been completed.

I will observe that I've never seen a movie from one of his books that comes close to capturing his own special brand of weirdness.
