For those who are interested in picking up Terminator: Salvation when it arrives on DVD and are curious as to what's in the "Director's Cut", here is a link to an article at /Films that explores what might be there:

The bottom line appears to be some nudity and violence, which pumps the PG-13 film up to an R rating.  I have yet to see the film, but when it does arrive on Blu Ray, I'll check out the price and make a decision from there.

While the film earned generally mediocre reviews, it still did pretty decent box office numbers and there are plenty of people defending the film's merits.

At the very least, I'm curious as to what's there.  We'll see.
