Do not read further if you at all care about seeing this film...Just a rumor now. But it's stupid enough to be true. http://www.aintitcool.com/node/36947
So really it throws out Marcus's character and John becomes the terminator. I honestly dont mind. Sure it's weird but I think the idea is kinda cool. Terminate John but not really.
Um... I've heard that from a different source so it could be true. Supposedly, Arnie has a cameo slated as the T1000 that kills him but that seems more unlikely than the John is a Terminator one.
T2 should have been the end. Really. They should have used that piece that got cut out with old John and Sarah Connor on the playground in the future where Judgement Day never happened at the end of 2, that way it would've been too difficult to explain any more sequels, and therefore they'd never have happened.
if they wanted to continue these movies, it should have been based off of the arm again. THe one the second T-800 lost in the steel mill as based in the Stirling books ( check them out if you havent already! ) Thats what I was hoping for when 3 came out, is that they found the second arm, the Terminator lost, and ran with that, major fail!
