The best thing about the scene is the now-famous story about Ridley Scott struggling to end it, and Hauer coming up with the dialogue in his trailer in a few minutes.
Is it true? I don't care, and I have no idea what attack ships on fire off the shoulder of Orion look like, or C-Beams glittering in the dark at the Tannhauser gate, yet coming from Hauer's noble killing machine, they sound epic, dramatic, awe-inspiring.
The last line, about those moments being lost like tears in rain, still makes me shed a few myself every time I watch it. It is poetry - pure and simple.
He has had a fine career outside of Blade Runner - even if he did drop off the radar for a while - but it is for this Rutger Hauer will be remembered and rightly so.
