Marty McFly

"I'm going to seize every moment."

"I've learned that resilience is strength."

"I'm going to build my own future."

"I believe in the impossible becoming possible."

"I'm going to live without regrets."

"I've learned that time is the greatest gift."

"This is heavy."

"There's that word again. Heavy. Is there something wrong with the Earth's gravitational pull in the future?"

"I'm your density. I mean, your destiny."

"Nobody calls me chicken."

"You built a time machine... out of a DeLorean?"

"I've got to hand it to you, Doc. When you come up with a crazy idea, you really commit to it."

"If my calculations are correct, when this baby hits 88 miles per hour, you're gonna see some serious stuff."

"1.21 gigawatts. 1.21 gigawatts. Great Scott!"

"You really are a handful, George."

"I guess you guys aren't ready for that yet. But your kids are gonna love it."

"This is it, this is the moment we've been waiting for."

"Don't be such a square."

"I'm your brother, man."

"You're my best friend, Doc."

"We need to talk."

"I can't go back to the future if there is no future."

"Wait a minute, wait a minute. What are you telling me, that you built a time machine out of a DeLorean?"

"That's why I'm here. I'm a time traveler from the future."

"I've seen what happens to you if you keep going down this road, George."

"You've got to be kidding me. You're telling me you made a time machine out of a DeLorean?"

"The way I see it, if you're gonna construct a time machine into a car, why not do it with some style?"

"That's pretty heavy stuff you're dealing with, Doc."

"I don't like violence."

"You're my best friend, and I care about you. That's all that matters."
