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 Türkische Früchte (1973), Das Mädchen Keetje Tippel (1975), and Der Soldat von Oranien (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.
