I have a question about the Back to the Future movies

I have III on right now.

Question, what is a 17 year old kid doing being friends with an old scientist who is not a friend of his family?

How did Doc and Marty become friends anyway?

Maybe they both had a fascination with energy?

I seem to recall the MJ Fox character doing something with a speaker / guitar amp that knocked him across a room?

I t must have been in the 1st film, since that's the only one I saw. So, watch that film, and see if that is the basis of their friendship. :shrug:

How did Marty and Doc get to know each other in the original timeline?

We never find out. In an early draft of the screenplay, Marty got to know Doc when he was 15; he would do odd jobs for him as an assistant, initially as an after-school job, but after some time they became friends:

MARTY: Doc Brown's all right - he's just a little hung up on time. A couple of years ago he showed up at my house and hired me to sweep out this garage of his. He pays me 50 bucks a week, gives me free beer...and gives me total access to his record collection - he's got this great old record collection.

Teenagers would do odd jobs for people in their town.

I remember the first time I asked some neighborhood kids if they wanted to rake my leaves up for $10 each back in '95. The kids were like "what?".

He gets to be friends with Doc Brown I think mostly because he and the Doc are both alienated from society. He does odd jobs around the "laboratory" of failed inventions for walking around money. Marty and his siblings are unpopular, older brother is a post-high school loser with no prospects, younger sister is well on her way to living alone with about two dozen cats. Mom is a drinker from a family of losers (Uncle Joey is a jailbird who doesn't make parole again), Dad is a total zero, relentlessly bullied by Biff Tannen.

The more intriguing question to me is how in the world did Marty the loser get together with Jennifer, an intelligent and attractive girl who could do much better?

Marty is a musician.

Never worked for me, and I was a heckuva lot cuter than Marty McFly even on his best day. Gotta be another reason. My extensive knowledge of the John Denver songbook, maybe?

Maybe hire Robert Zemeckis to direct the re-enactment?

come around and wax the car?

And George believes in redemption.

(I think I've spent too much time in GD today.)

During time travel flashes, while in the Hatch pushing a button, Doc came back with Sam Tyler. Sam split to make a bust with DCI Gene Hunt. Doc stuck around with young Marty to protect him from an enraged, knife wielding Al Swearingen...
