Don't care about the chromosomes, but was kinda hoping the group would be a bit more ethnically diverese, like with Lucy Liu or Salma Hayek in the group...
Maybe they have a male chef/friend who isn't white or black?!?
Who says there's going to be a Sigourney Weaver character?
Y'know, I'd get a real kick if someone like Chris Pratt or Channing Tatum (the only time I'd willingly watch Tatum) be the Dana-type character, if there is one (in the loosest sense, a love interest for one of the heroes).
And with that said, as much as I get disappointed by GBII, I'm still really impressed with how strong Dana was in that movie. Maternal instincts kicked in and she stood up to a god. That's impressive. A man who needs saving by the women but is still strong in his own right would be good for the movie (and definitely provide more material than just being a hostage in distress).
The original Ghostbusters had a wonderful dynamic between the characters.
Have you seen Kate Mckinnon on SNL? She's actually really funny on the show, and that's why I think she'll be great in the movie.
I feel these two posts also go together. Aykroyd, Murray, and Ramis all had Second City experience working together (indeed, the school's philosophy is heavily dependent on teamwork and supporting each other). Aykroyd and Murray had SNL experience, and Ramis and Murray had Stripes and Caddyshack.
Which makes me glad that Wiig, Jones, and McKinnon are on board, because they have past experience with each other (or at least concentric circles of experience) all from SNL. I'm still iffy on McCarthy, but like Wiig she has Second City experience as well.
