Wow. I think it looks pretty interesting. I am NOT a fan of Jolie but she seems to fit this part pretty well. I also noticed that Sharlto Copley, who I love, is in the film. Not sure how big his role is. You might remember him as Wikkus from District 9 or Kruger from Elysium.
The CGI in the trailer was passable. I like the idea of these old Fables being redone and seeing new spins on them. I've always loved, for example, the many different versions of King Arthur, Merlin and the Knights of the Round Table.
