I suppose a couple of those things off YouTube could be used like...(to put on one of the discs,or maybe there is some other extra stuff to make a 3rd Disc.

George Romero Interview(Page 1)(about Dawn)
George Romero G4 Icons(Page 1)

But this optional. I'd just like to see a Unauthorized Dawn of the Dead Ultimate Edition Companion Set including the materials I have. I'll give full credit to the person who does it.

EDIT:I found a hour long interview with George Romero,and while it does say he talks about Land,it says he talks about the rest of his career.

I found another hour long interview with Romero at http://www.retrocrush.com/podcast.html Episode 029
I also found a "Evening with Tom Savini" Interview in the May archive at www.deadpit.com
