It's been rumored that director McG was trying to get Linda Hamilton to do a voice over for Terminator Salvation, reprising her role as Sarah Connor, but last we heard, nothing had been finalized on that development. Now, someone who had a sneak peek at the film has told our friends at CHUD that Hamilton's voice is in the film.
According to the source, the voice over is not long, and it comes in very early in the film, but it fits very well into the context of the film, and is similar to the voice over work Hamilton did for Terminator 2: Judgement Day.
Unfortunately, other details were scarce from the source. But it seems that, at a minimum, the rumor about Linda Hamilton reprising her voice as Sarah Connor is true. This also speaks well for the tone of the film, and suggests that Hamilton at least tacitly approves of the new film.
In the highly anticipated new installment of "The Terminator" film franchise, set in post-apocalyptic 2018, Christian Bale stars as John Connor, the man fated to lead the human resistance against Skynet and its army of Terminators. But the future Connor was raised to believe in is altered in part by the appearance of Marcus Wright (Sam Worthington), a stranger whose last memory is of being on death row. Connor must decide whether Marcus has been sent from the future, or rescued from the past. As Skynet prepares its final onslaught, Connor and Marcus both embark on an odyssey that takes them into the heart of Skynet's operations, where they uncover the terrible secret behind the possible annihilation of mankind. Terminator Salvation explodes into theatres May 22, 2009.
