An oldie but a goodie, Back to the Future asks deep questions about our ability to change our future. What characteristics about us or our life is nature vs nurture? What is inherent and what is inherited? Marty faces his past and his future and his choices do not only change the trajectory of his life but the lives of all of those around him. It is a deep look at the nature of free will and our ability to influence our destiny through action and mindset.
Mr. Strickland: Doc? Am I to understand you’re still hanging around with Dr. Emmett Brown, McFly? Tardy slip for you, Ms. Parker. And one for you, Mcfly. I believe that makes four in a row. Now, let me give a nickel’s worth of free advice, young man. This so-called Doctor Brown is dangerous. He’s a real nut-case. You hang around with him, you’re gonna find yourself in real trouble.
Marty: Oh, yes, Sir.
Mr. Strickland: You got a real attitude problem, McFly! You’re a slacker! You remind me of your father when he went here. He was a slacker too.
Marty: Can I go now, Mr. Strickland?
Mr. Strickland: I know your band is on the roster for the dance auditions after school. Why even bother, McFly? You don’t have a chance. You’re too much like your old man. No McFly ever amounted to anything in the history of Hill Valley!
Marty: Well, history is gonna change.
Linda (Sister): Hey, Marty? I’m not your answering service, but while you were outside pouting over the car, Jennifer Parker called you twice.
Lorraine (Mom): I don’t like her, Marty. Any girl who calls a boy is just asking for trouble.
Linda (Sister): Oh, mom. There is nothing wrong with calling a boy.
Lorraine (Mom): It’s terrible! Girls chasing boys! When I was your age, I never chased a boy or called a boy! Or sat in a parked car with a boy!
Linda (Sister): Then how am I ever supposed to meet anybody?
Lorraine (Mom): Well, it will just happen. Like the way I met your father.
Linda (Sister): That was so stupid! Grandpa hit him with the car!
Lorraine (Mom): It was meant to be. Anyway, if grandpa hadn’t hit him, then none of you would have been born.
Linda (Sister): Yeah, well, I still don’t understand what dad was doing in the middle of the street.
Lorraine (Mom): What was it, George? Birdwatching?
George (Dad): What, Lorraine? What?
Lorraine (Mom): Anyway, your grandpa hit him with the car and brought him into the house. He seemed so helpless. Like a little lost puppy and my heart just went out to him.
Linda (Sister): Yeah, Mom, we know. You’ve told us the story a million times!
Marty: I gotta go! Thanks very much! You’re all great! See you all later… much later.
Stella (Lorraine’s Mother): He’s a very strange young man.
Sam (Lorraine’s Father): He’s an idiot. Comes from upbringing. His parents are probably idiots too. Lorraine, you ever have a kid who acts that way, I’ll disown you.
[Looking at the Video Recorder]Dr. Brown: This. It’s truly amazing. A portable television studio. No wonder your president has to be an actor. He has to look good on TV.
Dr. Brown: Next Saturday night, we are sending you back to the future!
Marty: Ok. Saturday’s good. Saturday’s good. I can spend a week in 1955. I can hang out. You can show me around.
Dr. Brown: Marty. That is completely out of the question. You must not leave this house. You must not see anybody or talk to anybody. And if you do, it could have serious repercussions on future events. Do you understand?
Marty: Yeah. Sure. Ok.
Dr. Brown: Marty, have you interacted with anyone else today besides me?
Marty: Yeah, well, I might have sort of bumped into my parents.
Dr. Brown: Great Scott! Let me see that photo again of your brother. Just as I thought. This proves my theory. Look at your brother!
Marty: Hey, his head’s gone. It’s looks like he’s been erased.
Dr. Brown: Erased from existence!
Marty: Listen, Doc. You know there’s something I haven’t told you about the night—
Dr. Brown: Please, Marty. No many should know too much about his own destiny.
Marty: You don’t understand!
Dr. Brown: I do understand. But if I know too much about my own future, I could endanger my own existence. Just as you have endangered yours!
Marty: Doc, about the future.
Dr. Brown: No! Marty! We’ve already agreed, having information about the future can be extremely dangerous! Even if your intentions are good, it can backfire drastically! Whatever you’ve got to tell me, I’ll found out through the natural course of time.
