CREDITS FOR PART 1.

We see Doc Brown's lab filled with clocks over the credits. Each clock is set to exactly the same time. They are also all 25 minutes slow. A robot tin opener opens a tin of dog food and empties the contents into a dog food bowl marked Einstein. The pile is high, it is clear that Einstein has not touched this food for a few days. Suddenly the TV and radio turn on.

Radio Advert: (v.o) October is inventory time. So right now, Statler Toyota is making the best deals of the year on all 1985 model Toyotas. You won't find a better car with a better price with better service anywhere in Hill Valley...

TV Newsreader: ...the Senate is expected to vote on this today. In other news, officials at The Pacific Nuclear Research Facility have denied the rumour that the case of missing plutonium was in fact stolen from their vault two weeks ago. A Libyan terrorist group had claimed responsibility for the alleged theft, however, the officials now infer the credence to a simple clerical error. The FBI...

The front door opens, and MARTY MCFLY, 17, walks in. We don't see his face just yet though.

Marty: Hey, Doc?

Marty: Doc. Hello, anybody home? Einstein, come here, boy.

Marty whistles.

Marty: What's going on? Wha- Aw, God. Aw, Jesus. That's disgusting. Where the hell is everybody?

Marty puts down his skateboard and it rolls along the floor to hit a box under the table - marked Plutonium! Marty is unaware of this. He plus his electric guitar into Doc's amplifier. He strikes a string, and the noise causes the amplifier to break. The force from this pushes Marty backwards, and he crashes into one of Doc's bookcases, causing the books and papers on it to fall off and land on his head. Marty lifts up his sunglasses - now we finally see his whole face, and notice that he resembles Michael J Fox quite a lot! :-)
