There where still a couple of bit's left - the presence of the mechanical fake owl in the office for instance. But I don't think that if Deckard followed Wilburism and called in a fake vet to care for his malfunctioning sheep then it would be quite as easy for the audience to question his authenticity. The whole fake police thing would have been pretty difficult to translate to the movie format as well - interesting when it got there though. For the true lack of the Philip K. Dick spirit you probably have to go to Total Recall - surprisingly good film but not really in touch with "We'll Remember It For You Wholesale". PS For the ultimate exploration of his mind have you read "I Am Alive and You Are Dead" by Emmanuel Carrere? Now out in paperback, £5.39 from Amazon UK. Reading it late at night almost managed to convert me to a new religion...
