Philip K. Dick only saw twenty minutes of the film before his death.
According to Dick's close friend and confidante Maer Wilson (who spoke to him daily until his death) Philip Dick never saw the completed film.
Philip K. Dick only met Ridley Scott one time – the day Phil was
invited to view the special effects months prior to the Blade Runner
premiere. Sadly that would be the only one of a few clips of the film
he would see. He also saw something on some TV show. Phil passed on in
March of 1982.
Having known Phil for almost ten years, our friendship had grown to
the comfort level you usually only get with the passing of years. I
was with him or talked on the phone almost every day the last year of
his life. The year that included the visit to the studio where we saw
the models for the sets and some of the props and other cool stuff.
That day is burned into my mind . . . even these 35 plus years later.
However, the special effects that Phil saw that day were what really
won him over. (Insert the “I loosened it for you” thought here.) We
sat next to each other with Ridley behind us. About eight people were
in the studio standing around while a woman photographed us.
It was explained that the music we would hear was not the one to be
used in the film. The opening scene from the film played, followed by
scenes with the blimp, the city, and the flying cars. As scene after
scene progressed, I felt Phil’s entire mood change.
When the clip ended, Phil turned to Scott in amazement. “You captured
the exact mood I was going for in my book! I can’t wait to see the
entire film be cause this was very impressive. It’s like you could see into my mind.”
The Other Side of Philip K. Dick.
Dick was invited by director Ridley Scott to a special screening of the film's opening scenes. Additionally he toured the set, watched some of the shooting, played with the props and saw some of the 'dailies' coming from the editing suite (as well as the "behind the scenes" footage on Hooray for Hollywood) so he certainly had some knowledge of what the finished product would look like on the big screen and approved of what he saw.
“So first we gave him a quick tour of the EEG shop, which I thought
might settle him down. But Dick didn’t seem impressed, even when we
showed him all the preproduction art and the actual models we’d used
for certain effects shots. (Then, after Dick and Ridley had a
meeting), we went into the screening room.”
“Dick was a bit guarded at first,” recalls Ridley Scott. “Until we
doused the lights, turned up the music, and ran the reel for him,”
However, according to Blade Runner’s coeffects supervisor, “Dick
didn’t say a word at first. He sat there for twenty minutes like a
statue. Then the lights came up, and Dick turned around to me. He said
in this gruff voice, ‘Can you run that again?’ So the projectionist
rethreaded and ran it again.
“Now the lights come up a second time. Dick looks me straight in the
eye and says, ‘How is this possible? How can this be? Those are not
the exact images, but the texture and tone of the images I saw in my
head when I was writing the original book! The environment is exactly
as how I’d imagined it! How’d you guys do that? How did you know what
I was feeling and thinking?!’
“Let me tell you, that was one of the most successful moments of my
career,” Dryer concludes. “Dick went away dazed.”
