Terminator 4 could be a lot more unpredictable than we'd expected, judging from a Warner Bros. press release that reveals a bunch of new plot twists and turns. Meanwhile, the movie has cast John Connor's wife Kate: it's Charlotte Gainsbourg (21 Grams.) This character, originally portrayed by Clarie Danes in T3 , sent the Terminator back in time to help them both after John was killed in their messy future. Another young actor named Jadagrace will be portraying Star. Plot details (and spoilers, of course) after the jump.

The future turns out to be different than the one John Connor was raised to believe in — and one factor behind the change in the time line is the appearance of a new character, Marcus Wright (Sam Worthington). In one version of the movie's script, Marcus has a much larger role than John Connor. Marcus appears in the future with no memory and no friends, and his last memory is of being on death row. Connor has to figure out where Marcus is from: the future or the past? The two of them team up to set out on a final mission to completely destroy Skynet but they discover a terrible secret behind the possible destruction of the entire human race.


Right now principal photography is taking place in Albuquerque Studios and on location throughout New Mexico.
