Terminator Salvation: The Future Begins director McG updated his blog earlier today.

The film maker shared insight on what fans can expect in the movie, while also addresses the spoilers concerning the ending that have been circulating around the Web.

Here are some of the more interesting nuggets McG shared in his blog:

• "This movie takes place several years after Judgment Day, but prior to 2029.

Just like it took a long time to get an HD plasma screen in our world, it took Skynet a lot of research and development to get to the T-800, and this movie explores that 'space between.' We have all been fascinated with the world after Judgment Day. Here it is."

• "In this film, there are Hydrobots that patrol the water, Transports that move human prisoners around, Harvesters that collect human beings as lab rats for Skynet and Aerostats that survey all that is going on with the resistance the world over."

• "Oh yeah, don't get too uptight about the prospect of the film being PG-13. We have entertained the idea of a PG-13 rating largely because Batman Begins, in my opinion, was made compromise-free. So we'll see. The movie comes first and it will be protected at all times…"

Bryce Dallas Howard is in negotiations to replace Charlotte Gainsbourg in Terminator Salvation: The Future Begins.

According to The Hollywood Reporter, Gainsbourg was originally set to portray Kate Connor, the wife of everyone's favorite human resistance leader, John Connor (Christian Bale). But the actress had to bow out due to scheduling conflicts with another film

Howard last starred as Gwen Stacy in Spider-Man 3 and next stars in the The Loss of a Teardrop Diamond.

Warner Brothers has released the following press release, hyping Terminator Salvation: The Future Begins:

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.

Christian Bale appears to be locked in to yet another franchise. At the Cannes Film Festival, it was announced that that Bale has signed on for all three of the new Terminator films, starting with Terminator 4, currently in production.

"Christian was our first choice and he's a big fan of The Terminator, so we're very lucky," said Victor Kubicek from Halcyon at the Cannes Film Festival. "But with Batman he's already done the whole franchise thing, so we weren't sure he'd respond."

"He read the script and he loved it, so he's signed on for all three," added Kubicek's business partner, Derek Anderson.

Next month, of course, Bale stars in his current franchise, portraying Bruce Wayne in The Dark Knight.

Rapper/actor Common has signed on to co-star in Terminator Salvation: The Future Begins.

Christian Bale, Sam Worthington, Anton Yelchin and Moon Bloodgood star in this follow-up to the wildly successful franchise. It's set for release on May 22, 2009.

To introduce Common to the non-rap fan, here's a video of the star in action:

According to The Hollywood Reporter, Moon Bloodgood is in final negotiations for the female lead in the upcoming Terminator follow-up, Terminator Salvation: The Future Begins.

Bloodgood will star alongside Christian Bale, Sam Worthington and Anton Yelchin in the fourth installment of the franchise, which is set for release on May 22, 2009.

Reportedly, Bloodgood - who is currently shooting Street Fighter: The Legend of Chun-Li - will play a no-nonsense and battle-hardened member of the resistance.

Moon Bloodgood is gearing up for Terminator Salvation: The Future Begins.

Anton Yelchin (upcoming Star Trek, Charlie Bartlett) is in negotiations to star as post-apocalyptic warrior Kyle Reese in Terminator Salvation: The Future Begins.

According to The Hollywood Reporter, Yelchin will play a teen version of Reese, the man who fathered world savior John Connor in the original Terminator film. Christian Bale will play John Connor in the movie, which is set for release on May 22, 2009.

Reese, one of the children who survived a machine-driven nuclear holocaust, befriends Marcus (Sam Worthington), an early edition of the Terminator cyborg played in previous films by Arnold Schwarzenegger.

In McG's film, the character is a young version of the one played by Michael Biehn, who traveled back in time in the original to impregnate Sarah Connor (Linda Hamilton) and father the world's future savior.

The film picks up with their son (Bale), now in his 30s, fighting desperately to save a decimated civilization against machines that have taken control.

Sam Worthington will star alongside Christian Bale in Terminator Salvation: The Future Begins.

The Australian actor recently portrayed the lead in the James Cameron-directed Avatar, as that famous director reportedly recommended Worthington to Terminator Salvation director McG.

Worthington will play the role of Marcus, a central figure in a three-picture arc that begins after Skynet has destroyed much of humanity in a nuclear holocaust. A group of survivors led by John Connor (Bale) struggles to keep the machines from finishing the job.

McG - the man behind the camera for Charlie's Angels and The OC - was recently hired to helm the fourth installment in the Terminator franchise. He recently discussed what fans can expect to see from Terminator Salvation: The Future Begins.

"[The filmmakers are prepping the picture right now," McG said to The213.net. "The script is largely done, whether or not we're able to prep off of it, obviously we want to continue to work on it, punch it up and we're hoping for an expedient finish to the writer's strike. But I've got my fingers crossed that in a week or two it will be over."

The director confirmed that Christian Bale will portray the heroic John Connor, while also hinting that No Country for Old Men's Josh Brolin might be in the running to play the film's terminator.

McG revealed that Terminator 4 will take place in 2019, post-Judgment Day, but added that "there are indeed some timeline issues" with respect to the continuity established not only by the first three Terminator films, but also now by the TV series Terminator: The Sarah Connor Chronicles.

"We're going to do what we can to respect them all," he said.

CHUD.com has released a few spoilers for Terminator Salvation: The Future Begins.

According to movie news source, the character of John Connor - already set to be played by Christian Bale - has a minor role in the film, which is meant to kick-start a brand new trilogy of films set in the future of the Terminator world.

The main character of Terminator Salvation is reportedly named Marcus, a man who was "put out of commission" before the machines take over on Judgment Day and is just waking up as the film begins.

The film is set in the future, approximately 15 years before the future scenes of the original Terminator movie. The Connor character appears only peripherally, but will supposedly have a bigger part in the planned second film.
