"The cast and crew of Star Trek wish to dedicate this film to the men and women of the spaceship Challenger whose courageous spirit shall live to the 23rd century and beyond..."

"They travelled back where 23rd century man had never gone before. To a mad, crazy, outrageous time: 1987."

"Only the technology of the future, can save what's endangering the past."

"The key to saving the future can be found only in the past."

"Beaming down to Earth December 12, 1986."

"And I don't think there's ever been any reason to show you what I'm capable of...but I'm telling you this now. Go out there and do whatever it is you want. There's no way in the world I can stop you, but don't come back here. And don't come near them. Any of them."

"What happens if it actually works?"

"If you always want what you can't have, what do you want when you can have anything?"

"[His first experience in the machine] Maybe it was the dramamine kicking in, but I remember this moment in the dark with the reverberation of the machine. It was maybe the most content I've ever been."

"Aaron, I can imagine no way in which this thing could be considered anywhere remotely close to safe. All I know is I spent six hours in there and I'm still alive... You still want to do it?"

"You know what they do with engineers when they turn 40? They take them out and shoot them."

"How many times would it take before he got it right? Three? Four? Twenty? I've decided to believe that only one more would have done it. I can almost sleep at night, if there's only one more. Slowly and methodically, he reverse-engineered a perfect moment. He took from his surroundings what was needed, and made of it something more. And once the details had been successfully navigated, there was nothing left to do but wait for the conflict. Maybe the obligatory, last minute moral debate until the noise of the room escalates into panic and background screams, as the gunman walks in. And eventually, he must have got it perfect, and it must have been beautiful with all the praise and adoration he had coming. He had probably saved lives, after all. Who knows what would have happened if he hadn't been there?"

"[narrating] Meticulous, yes. Methodical. Educated. They were these things. Nothing extreme. Like anyone, they varied. There were days of mistakes and laziness and infighting. And there were days, good days, when by anyone's judgment, they would have to be considered clever. No one would say that what they were doing was complicated. It wouldn't even be considered new. Except maybe in the geological sense. They took from their surroundings what was needed, and made of it something more."

"That is no static shock."

"What's worse, thinking you're being paranoid or knowing you should be?"

"I am trying, okay, I really am here."

"Are you hungry? I haven't eaten since later this afternoon."

"You're talking about making a bigger one."

"Terror has a new name."

"For me... that is a really difficult question Dr. Laurenson, because the world around me is shrinking... and the Four Horsemen of the Apocalypse are comin' to see me today, and they're not bringing flowers which... just makes it real difficult to get organized."

"Sometimes I think we live through things only to be able to say that it happened. That it wasn't to someone else, it was to me. Sometimes we live to beat the odds. I'm not crazy even though they thought I was. I live in the same world as everyone else. I just saw more of it, as I'm sure you have. They'll find my body tomorrow. You can check it out if you don't believe me. I've seen life after my death, and I'm telling you this because it's the only way to help you and your daughter have a better life of your own. Jean, you're gonna pass out one day smoking a cigarette and burn to death. Your daughter grows up living the same sad life you're living right now. And she misses you so much. Sometimes life can only really begin with the knowledge of death. That it can all end, even when you least want it to. The important thing in life is to believe that while you're alive, it's never too late. I promise you, Jean, no matter how bad things look, they look better awake than they do asleep. When you die, there's only one thing you want to happen. You wanna come back."

"I was 27 years old the first time I died. I remember there was white everywhere. There was war and I felt alive, but really I was dead."
