Well, they did on Philip K Dick. The recreational intake of the author of A Scanner Darkly was a key factor in the visions and delusions he brought to his work, says Philip Purser-Hallard
On first reading a Philip K Dick novel, many people wonder what kind of twisted mind could come up with such ideas. The answer is a very twisted mind indeed – even when writing science fiction, Dick wrote from experience. This is certainly true of A Scanner Darkly, perhaps the ultimate sci-fi drug novel, on which Richard Linklater’s new film is based. Starring Keanu Reeves – albeit in a more animated form than usual, courtesy of a surreal rotoscoping process – it tells of an undercover narcotics cop named Robert Arctor who loses his mind while trying to bust an illegal drugs trade.
