Minor correction, because this is often misunderstood:
> The famous monologue was improvised by Rutger Hauer
It wasn't improvised. Hauer rewrote the monologue by cutting a few words from the original script, and adding the "like tears in the rain", which he showed to Scott and Peoples, who liked it.
The original line in the script was: "I've seen things... seen things you little people wouldn't believe. Attack ships on fire off the shoulder of Orion bright as magnesium... I rode on the back decks of a blinker and watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments... they'll be gone."
