At New York Comic Con Linda Hamilton told MTV News that she was in talks to do a voice over for McG’s Terminator Salvation, but that they hadn’t come to terms and that she hadn’t yet read the material. It turns out that in the month since then she’s definitely read it – right into the movie.
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.
