"I've seen things you people wouldn't believe. Attack ships on fire off (the) shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Time to die." This one is just such a classic.
I hope everyone will forgive me for going slightly off-topic with this as its from a book as opposed to a film or TV show, but I wonder how many will recognise it's source.
“Arrest the lot of ’em. Conspiracy to cause an affray, going equipped to commit a crime, obstruction, threatening behavior, loitering with intent, loitering within tent, hah, traveling for the purposes of committing a crime, malicious lingering and carrying concealed weapons.”
“I don’t think that one—”
“I can’t see ’em.”
"those who live in darkness wander aimlessly" Yami Numatsuay Decedents of Darkness. An old obscure anime I came across in the early 2000's. Nothing too special but that line was repeated at the end of every episode and I always liked it.
