SciFi Wire has quoted Guillermo as saying that Hellboy 2 is “officially a go”, but he says the studio is just waiting for proof that the movie can be put together for the slated budget. “”It’s a pretty low number for the size of movie we want to do. Adjusted for inflation, it’s as low a budget as the first one, but the scale of it is about twice the first one,” says GDT.
Also of note, GDT talks briefly about the theme:
“The heart of the film is that fantasy has been grounded by reality,” del Toro said. “It’s been ground to dust by reality. Hellboy is fighting for the humans, but he starts realizing that maybe not everything is right in the way that he does things.”
