There has been a lot of news about Terminator 4. The key point is whether the old faces will appear again, and the most critical factor is Arnold Schwarzenegger. There are rumors that he might join with an eight-figure salary, but so far, he has been busy pursuing greater ideals...
However, without his participation, Terminator 4 would lose much of its appeal. Therefore, the production team will try every possible way to include Schwarzenegger in the movie. If necessary, they might even use someone who looks like him, or as was done with Brandon Lee in "The Crow," create a digital version of Arnold's face using CG...
Still, there are plenty of good news. Nick Stahl, this handsome actor who will become the leader of humanity, made a brief appearance in the third movie but still had a strong presence. According to Joblo, he will be joining the cast, which means he might truly take on the role of the main leader in the war in Terminator 4.
