"It’s not about causes, Rejoice. I'm steeped in the blood of it all. It's my reason for being: to do the unthinkable, to bring this whole sorry chapter of cosmic history to an end, one way or another. In short... I'm a monster."

"Doctor no more."

"Time Lords of Gallifrey, Daleks of Skaro; I serve notice on you all. Too long I’ve stayed my hand. No more. Today, you leave me no choice. Today, this war will end. No more. No more."

"Great men are forged in fire. It is the privilege of lesser men to light the flame."

"Go back. Go back to your lives. Go and be the Doctor that I could never be. Make it worthwhile..."

"Oh... Yes, of course, suppose it makes sense... Wearing a bit thin! I hope the ears are a bit less conspicuous this time."

"There is a moment, after regeneration, when the guttering soul of the old man looks out through the eyes of the new. So it was the Doctor who looked into the mirror-- but it was me who looked back."

"I’m sorry... I couldn’t save you. I tried! He tried. I couldn’t save him either. Did he really think he could stay apart from the War? Play the dashing romantic hero forever? How full of hope he was… How naïve. How foolish."

"If you have been inside my head, then you know what I've seen. The suffering. Every moment in time and space is burning. It must end. And I intend to end it the only way I can."

"The problem with helping my people... is that it often makes things far worse. I don't take orders. If I help, it's on my own terms."

"[to Hartnell] "Not blessed"? What the hell are you talking about? Of course you're blessed! You're gonna be "Doctor Who", aren't ya? Perfect choice for my little show - well, my idea, anyway. That's what I do - ideas. One day I came into ITV - "I got an idea," I said. "The Avengers". "What's it about?" they said. "How the hell should I know?" I said. "But what a title!""

"Doctor... who?"

"Be a producer, Verity. Find a way to deal with this stuff. Or are ya out of your depth?"

"[in 1964, showing Lambert a newspaper] Verity, take a look at this. Take a look at this! General de Gaulle. "Degaullek" - "Non! Non! Non!" [shows picture of de Gaulle as a Dalek] We've really got something here. They love us."

"[after the premiere of The Daleks] Ten million viewers for your bug-eyed monsters. Ten million. So... what do I know about anythin'? [winks] Well done, kid."

"You can't have Doctor Who without Doctor Who, can you?"

"Sacha Dhawan as Waris Hussein, original director"

"Reece Shearsmith as Patrick Troughton/The Second Doctor"

"Brian Cox as Sydney Newman, creator"

"The old curiosity shop, the Roman forum, the Hanging Gardens of Babylon, symphonies in pencil and ink... so surely you can turn your hand to my teeny little time machine?"

"Jeff Rawle as Mervyn Pinfield, associate director"

"Jessica Raine as Verity Lambert, original producer"

"Lesley Manville as Heather Hartnell, William Hartnell's wife"

"[clip of the real Hartnell, from The Dalek Invasion of Earth] I want you to belong somewhere, to have roots of your own. With David you will be able to find those roots and live normally like any woman should do. Believe me, my dear, your future lies with David and not with a silly old buffer like me. One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine."

"[catchphrase] Pop-pop-pop!"

"Wish I knew what bloody dimension I was in..."

"[to a friend, when asked about finding a job in TV] "You're only a production assistant, dear, it's a bit of a leap." I'm giving myself a year, Jackie - get on in television, or get out."

"[on the script for An Unearthly Child] What is this? What are we going to do with this? Stone Age man going "ug"? It's crazy! Cavemen and doctors and disappearing bloody police boxes!"

"David Bradley as William Hartnell/The First Doctor"

"Claudia Grant as Carole Ann Ford/Susan Foreman"

"How many regenerations did we grant you? I've got all night..."

"Are all the bells ringing? The whole Cloister?"

"What is it? Is the firing squad afraid of the unarmed man?!"
