I don't know if it's official, but on IMDb it states that following crew members is hired for Season 3:
- Nathan Alexander (Props, since Cherokee Rose.)
- Sean Ryan Jennings (Set designer. New crew member)
- Daniel F. Green (Location Manager. Upgraded from Location Assistant.)
- Bear McCreay (Music. It's offical that he will continue)
- Greg Nicotero (Make-up. We knew that)
- Howard Berger (Make-up. Continues)
- LeShae Ann Nash (Construction Buyer. Continues)
- Brad Carey (Location Assistant. New crew member)
- Brent Bernhard (Stunts. He will do stunts for a character from Season 1)
- Troy Faruk (Will apear as a character named 'Sean' and as Stunt man)
Might just be me that concerns about the crew members, but some prop people are better than others. Yea, i know. I'm a freak.
The weirdest one might be Troy Faruk and Brad Carey; A character leaked from IMDb? And Brad Carey never did anything besides TWD. He's probably related to somebody on the set.
That's it. KJ
