About a week ago, I was looking up the blue ray details when it came to my attention that a DVD version will also be released this October 5th.What I am trying to find out is if anyone here might know what the key differences are in the two releases.I mean, I have the 2005 version of “King Kong” on DVD, except that it comes with three DVDs….everything you need to know from Peter Jackson and company is in there.Is there any chance that “The Exorcist” DVD will have at least a little bit of what the blue-ray has?
