Top 5 Science Fiction Films:

Stanley Kubrick's 2001: A Space Odyssey
"Open the pod bay doors, Hal"

Ridley Scott's Alien
"You still don't know what you're dealing with do you? A perfect organism. Its structural perfection is matched only by its hostility."

Ridley Scott's Blade Runner
"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 Tannhauser gate. All those moments will be lost in time, like tears in rain."

James Cameron's The Terminator
"It can't be bargained with. It can't be reasoned with. It doesn't feel pity, or remorse, or fear. And it absolutely will not stop, ever, until you are dead."

Andy and Larry Wachowski's The Matrix
"Buckle your seatbelt, Dorothy, 'cause Kansas is going bye-bye."
