I have to declare from the off: I love theBack To The Futurefilms.

Utterly, utterly love them.

The scripts are tight, the films are exciting, the characters brilliant.

Whats not to like?

But there are little plot holes and questions.

Not one of these points dampens my enjoyment of the films in any way.

But they sure did get me thinking…

The conundrum is this: you tend to remember the people who brought you together in life.

you might find Eds DVD where he talks about this righthere.

And its this: there has to be two time machines in 1885.

Either way, theres surelysomethingof use in the second car.

Of course, there are arguments why that car cant be touched.

And secondly, if the alternative car was used, then Marty are you following this?

wouldnt have been able to get back to 1885 in the first place.

Because if it was fundamentally tampered with or used, thatd make it either redundant of non-existent in 1955.

Which would, of course, create a paradox to bring down the universe, as you well know.

In 1885, the big problem Marty and the Doc face is that they cant get hold of gasoline.

Lets get ultra-nerdy, then.

After all, the sole reason Marty goes back to 1885 is to save the Doc.

So,why would it have killed the film?

The Doc who got sent back to 1885 is the older one.

Granted, thatd make for a much shorter film, but surely its the logical thing to do?

There are further ramifications, too.

He would know about Clara before Marty showed him the cutting he took back to 1885.

Yet,hes never heard of her when he sees her name for the first time.

It might, of course, all create another alternative timeline, which in turn would have further consequences.

But would that affect the older Doc, as seen in 1885, anyway?

There is precedent for this.

Thus, its a strategy that would also, surely, work if a letter was sent from 1885?

After all, pictures from photographs in the movie take time to disappear.

And Martys hand only starts to disappear in the first film when events are going very badly wrong.

However, think back to the first film.

Einstein gets sent one minute into the future.

He doesnt exist in 1985, until he returns.

Does your head hurt yet?

Yet, surely older Jennifer would know that younger Jennifer was in the house?

And surely, therefore, she would be expecting her to be?

Take the argument further, and older Marty would know what was coming, too.

However, that presents a problem.

The get-out clause here is that it takes time for changes to feed along the time lines.

There doesnt even appear to be sufficient depth to said opening to hold a bear.

And yet, one appears.

Its like a magic bear.

Why, then, do they try and get the almanac at the point where its given to Biff?

There is a solid counter-argument here.

Although for the Doc, youd suspect, not impossible… Because Marty said no?

Ah, how about calling him yellow?

Heck, why doesnt Lorraine call him chicken for not cracking on with his music career?

Or call him a chicken for not being a chicken?

The Back To The Future trilogy arrives on Blu-ray today.
