"End titles: His machine was never perfected, though it generated a whole field of research into what became known as "Turing Machines". Today we call them "computers" (Above quote corrected): Historians estimate that breaking enigma shortened the war by more than two years saving over 14 million lives. It remained a government-held secret for more than 50 years. Turing's work inspired generations of research into what scientists called "TURING MACHINES," Today we call them computers."

"Alastair Denniston: Double agents are such bastards. Isolated loners. No attachments to friends or family. Arrogant. Know anybody like that?"

"Benedict Cumberbatch - Alan Turing"

"I know it's not ordinary. But who ever loved ordinary?"

"Headmaster: [to a young Alan, about his note-passing] You and your friend solve maths problems during maths class because the maths class is too dull?"

"Keira Knightley - Joan Clarke"

"Christopher Morcom: Sometimes it is the people no one imagines anything of who do the things no one can imagine."

"Of course machines can't think as people do. A machine is different from a person. Hence, they think differently. The interesting question is, just because something thinks differently from you, does that mean it's not thinking?"

"Sometimes it is the people no one imagines anything of who do the things no one can imagine."

"Think of it. A digital computer. Electrical brain."

"Heil Hitler. Turns out that's the only German you need to know to break Enigma."

"No one normal could have done that. Do you know, this morning... I was on a train that went through a city that wouldn't exist if it wasn't for you. I bought a ticket from a man who would likely be dead if it wasn't for you. I read up on my work... a whole field of scientific inquiry that only exists because of you. Now, if you wish you could have been normal... I can promise you I do not. The world is an infinitely better place precisely because you weren't."

"Matthew Goode - Hugh Alexander"

"The true enigma was the man who cracked the code."

"Are you paying attention? Good. If you are not listening carefully, you will miss things. Important things. I will not pause, I will not repeat myself, and you will not interrupt me. You think that because you're sitting where you are, and I am sitting where I am, that you are in control of what is about to happen. You're mistaken. I am in control because I know things that you do not know. [pause] What I will need from you now is a commitment. You will listen closely, and you will not judge me until I am finished. If you cannot commit to this, then please leave the room. But if you choose to stay, remember you chose to be here. What happens from this moment forward is not my responsibility. It's yours. Pay attention."

"Some people thought we were at war with the Germans— incorrect. We were at war with the clock. Britain was literally starving to death. The Americans sent over 100,000 pounds of food each week, and every week the Germans would send our desperately needed bread to the bottom of the ocean. Our daily failure was announced at the chimes of midnight. And the sound would haunt our unwelcome dreams."

"Do you know why people like violence? It is because it feels good. Humans find violence deeply satisfying. But remove the satisfaction, and the act becomes... hollow."

"When people talk to each other, they never say what they mean. They say something else and you're expected to just know what they mean."

"Was I God? No. Because God didn't win the war. We did."

"I am a pervert. I'm an exhibitionist. I'm a masturbator. And a killer... like you."

"Careful with that machine. It'll eat you up."
