Cooper: Dr. Mann there's a 50/50 chance your gonna kill yourself.
Dr. Mann: Those are the best odds I've had in years.
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. And that rules out telling a 10-year old that the world's ending.
Dr. Brand: I'm not afraid of death. I'm an old physicist - I'm afraid of time.
Cooper: Everybody ready to say goodbye to our solar system?
Romilly: To our galaxy.
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.
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.
Doyle: We have a mission.
Cooper: Yeah, and our mission is to find a planet that can habitate the people living on Earth right now. Okay? Plan A does not work if the people on Earth are dead by the time we pull it off.
Cooper: I'm coming back...
Young Murph: [crying] When?
Cooper: We're still pioneers, we barely begun. Our greatest accomplishments cannot be behind us, cause our destiny lies above us.
Brand: You might have to decide between seeing your children again and the future of the human race.
Principal: We didn't run out of planes and television sets. We ran out of food.
CASE: Ranger 2, prepare to detach.
Brand: What! NO, NO! Cooper! Cooper, what are you doing?
Cooper: Newton's third law. You've got to leave something behind.
Brand: You said there were enough resources for both of us!
Cooper: We agreed, Dr. Brand... ninety percent.
Cooper: We'll find a way, Professor, we always have.
Dr. Brand: Driven by the unshakeable faith, the Earth is ours?
Cooper: Not just ours, no. But it is our home.
Young Murph: What are you gonna do with it?
Cooper: I'm going to give it something socially responsible to do. Like drive a combine.
Young Murph: Can't we just let it go? It wasn't hurting anybody.
Cooper: This thing needs to learn how to adapt, Murph. Like the rest of us.
Donald: Popcorn at a ball game is unnatural. I want a hot dog.
Young Murph: I worked out the message. One word. Know what it is? Stay. It says stay, Dad.
TARS: I wouldn't leave you behind... Dr. Brand.
