Philip K. Dick personally approved of Rutger Hauer, describing him as, "the perfect Batty-cold, Aryan, flawless".
After Philip K. Dick saw Harrison Ford as Rick Deckard on-set, Dick declared: "He has been more Deckard than I had imagined. It has been incredible. Deckard exists!"
The final scene was shot hours before the producers were due to take creative control away from Sir Ridley Scott.
Director Sir Ridley Scott cast Rutger Hauer in the role of Roy Batty without meeting him. He had watched his performances in Turkish Delight (1973), Katie Tippel (1975), and Soldier of Orange (1977), and was so impressed, he cast him immediately. However, for their first meeting, Hauer decided to play a joke on Scott and he turned up wearing huge green sunglasses, pink satin pants, and a white sweater with an image of a fox on the front. According to Production Executive Katherine Haber, when Scott saw Hauer, he literally turned white.
