"The pictures remind you of something that can never be recaptured, the time is gone, the only thing you know is the present. That's all that's knowable and even the present isn't knowable. The present becomes the past... so you really don't know anything."

You get to a certain moment where you realize all those humans who landed on the moon did so in between Chris [Nolan] being born and me being born and no one had gone back since, all these Super-8 films we grew up watching of rocket launches, you get to a certain age and you realize all the speeches about going back, they're speeches, there's no money there, we're not going back.

— Jonathan Nolan
