20 Things You Didn't Know About Blade Runner
13. Joe Turkel Had To Use Cheat Sheets For Many Of His Lines
Eldon Tyrell, the industrialist and inventor of Blade Runner's replicants, spends most of his screen-time spouting impenetrable technical dialect - from the minutiae of the Voight-Kampff test to the failings of ethyl methanesulfonate. Actor Joe Turkel, who played Tyrell, had tremendous difficulty remembering these long and labyrinthine monologues.
To help him, the crew had text banners held up offscreen matching his eye line so that he could read his lines without stumbling over the technical jargon. However he still had great difficulty as the huge, thick glasses that he wore impeded his vision so much that the cards were still almost unreadable. If only Google Glass had been a thing back in 1982.
