Yesterday at Comic-Con International 2008 we "sort of" got director McG to reveal some details about Arnold Schwarzenegger's possible CGI involvement (Here's a theory: Arnold's face CGI'd over Austrian body builder Roland Kickinger's body, anyone?) in the fourth Terminator installment, Terminator Salvation.

As well, the rest of the cast revealed some details about their individual characters in the 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. While visiting Comic-Con 2008, we hooked up with Terminator Salvation: The Future Begins director McG and his cast to get the lowdown on this upcoming film.
