Not Surprisingly, 'Terminator' Series Likely To Extend Past Next Movie

With the release of "Terminator: Salvation" little more than a month away, two new posters have been released and director McG revealed he already has planned two more sequels.

The two new posters for the movie (which will be released May 21 in the U.S., May 22 in Canada and June 3 in the U.K.) are shown at right.

As for the sequels, McG said he would like to make two more -- provided audiences want to see them.

"I would never presume there would be another picture -- that is up to the audience," McG told MTV Movies. "But if the audience jumps up and likes it and wants another one, Christian [Bale] and I have been talking about it and we’ll see what happens."

McG said "Terminator: Salvation" sets the table for more movies.

"There’s an arc of story [in the new sequels]. This arc will be left open with the ending of Salvation, which will point to a Terminator 5 film. The ending is indeed elliptical and it challenges the audience," he said. "It’s not a happy little bow of an ending at all. The ending is tough and requires reflection, and in some degrees it bifurcates the audience. You walk back to the car and one person thinks it means this, and the other person thinks it means that."

In addition to Bale, "Terminator: Salvation" also stars Helena Bonham Carter and Bryce Dallas Howard. And, in an odd twist, the movie features Sam Worthington, Common and Anton Yelchin, three actors who have been rumored to play Green Lantern on screen.

And finally, what would a Terminator movie be without Arnold Schwarzenegger? Apparently, audiences want have to find out just yet as Schwarzenegger is set to make a cameo appearance in the movie.

However, it's a tightly-kept secret as to what that cameo will entail. So secret, in fact, that Schwarzenegger's co-star Terry Crews has no idea what it is.

“I don’t know; I haven’t seen it. They only gave out pages of the script,” said Crews. “It was crazy. It was very, very secretive."
