This world's a treasure, but it's been telling us to leave for a while now.Cooper
Brand: Couldn't you've told her you were going to save the world?
Cooper: No. When you become a parent, one thing becomes really clear. And that's that you want to make sure your children feel safe.
Doyle: You can't just think about your family. You have to think bigger than that.
Cooper: I'm thinking about my family and millions of other families.
Cooper: Everybody ready to say goodbye to our solar system?
Romilly: To our galaxy.
We're still pioneers, we barely begun. Our greatest accomplishments cannot be behind us, cause our destiny lies above us.Cooper
Cooper: You don't believe we went to the Moon?
Ms. Kelly: I believe it was a brilliant piece of propaganda, that the Soviets bankrupted themselves pouring resources into rockets and other useless machines...
Cooper: Useless machines?
Ms. Kelly: And if we don't want to repeat of the excess and wastefulness of the 20th Century then we need to teach our kids about this Planet, not tales of leaving it.
Cooper: You know, one of those useless machines they used to make was called a MRI, and if we have one of those left the doctors were have been able to an assist to my wife's brain, before she died instead of afterwards, and then she had been the one sitting here, listen to this instead of me which'll be a good thing because she was always the... a calmer one.
Dr. Brand: Not sure of what I'm more afraid of, them never coming back, or coming back to find we've failed.
Murph: Then let's succeed.
Dr. Brand: We need the bravest humans to finds us a new home.
Cooper: But the nearest star is over thousand years away.
Doyle: Hence the bravery.
Murph, I love you, forever.Cooper
Dr. Brand: We must confront the reality that nothing in our solar system can help us.
Cooper: Now you need to tell me what your plan is to save the world.
Dr. Brand: We're not meant to save the world. We're meant to leave it, and this is the mission you were trained for.
Cooper: I've got kids, professor.
Dr. Brand: Then get out there and save them. We must reach far beyond our own lifespans. We must think not as individuals but as a species. We must confront the reality of interstellar travel.
Young Murph: Dad, why did you and mom name me after something that's bad?.
Cooper: Well, we didn't.
Young Murph: Murphy's law?
Cooper: Murphy's law doesn't mean that something bad will happen. It means that whatever can happen, will happen.
Brand: There's the mountains!
Cooper: Those aren't mountains, they're waves.
