If you'd preffer not to sit through an hour of whining and poor acting it will be online around 9pm here.

Also we have some detials on what's going to happen in the film!

After a long vacation in outer space Superman returns to Earth to find Lois banging some other guy and Lex Luthor President of the United States. Instead of turning back time like in the first film Superman decideds humans just aren't worth all the fuss and throws the Earth into the sun. Now we've heard here at PAO the last few moments of the film will end like this,
After tossing the Earth into the sun Superman begins to fly around space. But instead of the John Williams score playing we hear Metallica's "Where ever I may rome" as Superman whips out his Ipod and jams out in space!

And Scene!
