This is my theory on the new nazi zombie map, Call of the Dead. So in the insider moves trailer they show george romero sitting in his directors chair talking about how he had read some nazi documents doing research for a WWII movie. He says he was astonished at what he had found. I believe he is talking about the 935 group. Keeping the story relavent to the other nazi zombie maps.
At 1:55 at the end of the inside xbox video there is footage of george standing with danny and robert before danny hits robert in the head with the butt of his machete. There is no electricity going around george at this moment in the trailer and this is what makes me believe that george is playing the role of the director in the game. As the director in game he will be pushing you along through the map trying to get you to hold up in different positions. George is very slow from what is shown making it possible to hold up in certain areas but not for long.
Another note, the characters in the game refer to eachother in their real world names, it is danny trejo playing danny trejo. This makes me believe that this may be a movie set over ran by zombies. or maybe it is literally a movie being shot by george "the director."
Tell me your thoughts.
