...Her voice, anyway.

It has been knows for a while that Linda Hamilton (the star of Terminator and T2) had been in negotiations to appear in the upcoming McG directed Terminator: Salvation.
Well it turns out that not only have the negotiations been resolved but her part has already been cut into the movie. Apparently her only presence is in the form of a voice over towards the beginning of the film, presumably explaining how we got from T3 to Terminator: Salvation. I would have preferred to see her in the flesh, perhaps in some sort of flashback, but a disembodied voice is better than nothing.

A source who has seen the film confirms to us that Hamilton's voice over is in the film, and that it works very well in context. Her voice over is not long, and it comes at the very beginning of the movie; the source compared it in tone and style to her voice over in T2.
Unfortunately that was all I could get - this source was incredibly mum about all other details. But that little bit of continuity - the presence of Sarah Connor - is going to be present in Terminator Salvation.
Now that has been confirmed, what do we think about the rumors of an Arnie cameo?
