Like in that Superman film?

I believe that the idea in the Superman movie was that he, by travelling at the speed of light - or perhaps even faster - started to travel backwards in time. As he travelled backwards in time, the earth, to him, appeared to be turning backwards.
So if you could travel back in time AND still observe the earth whilst doing so, it would appear to spin backward but would nevertheless still be obeying the laws of physics which are, as far as I know, time reversible.
So spinning the earth backwards would not cause time to reverse. Reversing time would cause the earth to appear to spin backwards.

In a word - no. in area there is not any North, South, East or West. neither is there up or down. so in fact there is not any "backwards" in area till there in a pre-defined "forwards". As there is not any forwards that is thoroughly acceptable, the Earth can spin any way imagineable and could no longer ever be spinning backwards. If the Earth exchange into to start spinning opposite to the way it is spinning now, it would could first decelerate, which might reason us all to die. it would take an exceptionally long term for it to get returned to the fee at which it is spinning now, if it ever did. yet another draw back to the Earth ceasing to spin is that each and every thing involved in it would end orbiting and shoot right this moment at it. If it is complicated(it confuses me too) then i'm going to attempt to furnish a answer it somewhat is way less complicated to understand: The Earth isn't at present spinning forwards, that is in straightforward terms spinning.

No! That Superman film is fantasy, not based on scientific speculation.
Flying backwards is done NOW, by airplanes, to no effect on time, by going in BOTH directions!
Flying backwards does not change the direction of time, but for some unknown reason driving backwards does!!!!
Just kidding ;-)
Time is just a human construct. God did not decide the length of an hour (although he does actually decide the length of time in a day).
You can build clocks to go back if you want, but time goes forward in THIS limited existence.
In fact you can move the hands of time (on our clocks), and we do twice a year, but the effect is only true of time because mankind says so!
All humans experience their lives linearly, in this limited mortal corner of the universe.
In fact, Einstein showed that you could break the time barrier by travelling FORWARD, faster than the speed of light.
Just as jets break the sound barrier by travelling FORWARD, faster than the speed of sound.
Einstein figured out that time was very limited, only to this time space continuum.
He theorized, as the Bible said, time is not existing everywhere.
It does NOT exist in the dimension of God's heaven, where we will not grow old.

No, it wouldn't. The spinning backwards of the Earth in Superman was meant to illustrate that time was going backwards. It's no different from setting your watch back an hour - it just resets your watch, do you get that hour you just lived back again.

Actually it would not. It would probably lead to the destruction of the planet due to the stress that would be put on the magnetic fields due to the change. Imagine when you are driving in a car and you slam on the brakes how things in the car continue to move in the same direction while/after you have stopped. Well, imagine that for a whole planet, oceans, buildings, people. In addition, the force to cause like that something to happen would have to be tremendous and would contribute to the devastation that would be caused.

the only things that would change is the way the sun rises from east to west would then be west to east and depending on the time when this switch would occur the lighted portion of the earth would change at say 12:00 because the sun and time are not lined up the way they were before

No, but it would make the sun rise from the opposite side.
Not to mention probably mucking up or ecosystems, and perhaps our orbits.
The Earth spins as well as orbits. If it went in reverse orbit it still wouldn't change the flow of time since it's just a path - driving your car backwards doesn't make you go back in time, it just makes you go backwards.

The only thing that would do is make the sun rise in the west and set in the east. Assuming it spins at the same rate, we would measure time (seconds, minutes, etc.) to be the same, i.e. still 24 hours in one day.

Try running backward and see if time flows backward

no, try walking backwards- does time reverse? Also - how would the earth start spinning backwards anyways... random!! but actually it would be cool if that did happen and time reversed.. but that would mean if earth spun forward again, we would be in the future- right?
