I only watched some parts of the director's cut. Not the whole movie from the beginning. Here are some descriptions of the new stuff:
Here's some quick descriptions
There's a T-1 Unit attack scene which is just a few second and doesn't add much. It's not even exciting, it doesn't even fire it's miniguns and doesn't kill any human.
Ashdown gun to John's head:
Ashdown: John Connor, prophesized leader of the resistance. Soldier, you put every man and woman in this sub in jeopardy with your little frogman stunt.
Let's get one thing straight. I don't believe in prophecy. Not when one can rewrite the future [gun to John's head] in a heartbeat. Are we on the same page?
Connor: Yeah, we're on the same page.
[gun away]
Ashdown: Good. Good. So soldier, what the hell are you doing here?
Connor: What did we find down there?
etc
The deleted scene of topless Blair Williams is slightly longer (then my uploaded scene) with her walking to the spot she undresses after she left her gun on another place (= 6 secs). I'm still wondering why she even turns to Marcus if she doesn't want him to see her boobs. Then there's 2 more secs or Marcus closing a door of a car before going back to theatrial cut. Still badly edited with the rain if you ask me.
Marcus pushing a screwdriver through a guy's shoulder, pinning him down on some wood.
Later the guy pulls out the screwdriver while screaming in pain. He attacks Marcus, but Marcus catches his hand. Then a guy behind Marcus un***** a shotgun (marcus hears the click and realizes what's happening behind him while holding the screwdriver guy). He turns around with the screwdriver guy in front of him while the shotgun guy shoots, shielding himself against the bullet with the screwdriver guy.
More (ridiculous) talk between Blair and Marcus during the campfire scene before the body heat question.
Blair Williams: Thinking about your past?
Marcus: ...
Blair Williams: You know what I've learned, Marcus? Is you can focus on what is lost or you can fight for what is left.
Marcus: ...
[start body heat nonsense]
When Kyle arrives at the Skynet, I think there's an extra 1 second shot of the guy climbing the fence. You see him get shots from behind. Then a quick shot from the front of some bullets hitting the guy. THIS WAS NOT IN THE THEATRICAL CUT!
John Connor vs. Marcus extra dialogue
John: Where were you manufactured?
Marcus: I was born August 22, 1975.
Marcus: I know you. etc
More John Connor radio message (worthless addition if you ask me, I mean what has Sarah to do with acting like machines?):
John Connor: If we attack tonight, our humanity is lost. I once knew a woman who told people to fear the future, that the end was coming, that all would be lost. Nobody wanted to hear her truths. Society locked her away. That woman was Sarah Connor, my mother. Now we know that what she predicted has all come to pass. Command wants us to fight like machines. etc.
Extra end credits. After the normal credits, there appears another short credits list for the director's cut with 5 names (including 1 for a film editor)
The director's cut doesn't add anything in my opinion from I have seen. It doesn't improve the movie. McG better includes all deleted scenes on the DVD.
